After the license: the part nobody teaches
Passing the exam gets you a license number. Getting paid, staying out of trouble with the CSLB and keeping that number is a second education, and most new contractors get it the expensive way. We put it inside the course, at no extra cost, so you get it the cheap way.
Every lesson below is written from the statute or the code section, cites the .gov source, and shows the month it was last checked. You can read the summary of any lesson free. The full method, the worked cases and the templates are inside Lifetime Access.

Phase 0
From Pass Letter to License Number
7 lessons
- LessonThe pass letter is not a license: the issuance checklistPassing both exams earns you a letter, not a license number. CSLB will not issue the number until the initial license fee, the $25,000 contractor's bond, the qualifier bond if you owe one, and a workers' compensation certificate or exemption are all on file, and you have 90 days from the notice before the whole application goes void. This lesson is the checklist, in the order that avoids a second trip.Current as of September 2026
- LessonThe $25,000 contractor's bond, and the second bond most qualifiers do not know they oweEvery California contractor files a $25,000 contractor's bond. A qualifier who is not the sole owner or a general partner also files a second $25,000 bond of qualifying individual, unless they own 10% or more and certify it. The bond is not insurance for you: it pays homeowners, defrauded customers and unpaid employees, and then the surety collects from you. Here is what each bond does, who it protects, what it costs in practice, and the one word you may never put in an ad.Current as of September 2026
- LessonWorkers' compensation: the rule as it actually reads today, and the date it changesMost advice online says every California contractor needed workers' compensation by January 1, 2026, employees or not. The statute on the books today says something different: a C-10 with no employees may still file the exemption, and the exemption disappears for everyone on January 1, 2028 (SB 216 as amended by SB 1455). What is already true today is harsher than most people think: hire one person after filing an exemption and the license is suspended by operation of law, with a minimum $10,000 civil penalty for a sole owner and $20,000 for an entity.Current as of September 2026
- LessonSole owner, RMO, RME, partner: which qualifier you are, and what you just signed up forThe person who passed the exam is the license's qualifier, and the law gives that person a job: supervision and control of the company's construction operations. A sole owner qualifies for themselves. A corporation or LLC qualifies through a responsible managing officer or a responsible managing employee, and an RME must be a real, permanent employee working at least 32 hours a week or 80% of the hours the business runs. Here is what each path requires, how a qualifier can serve more than one company legally, and the 90-day clock that starts the day a qualifier leaves.Current as of September 2026
- Lesson"Just put your number on it": why renting your license is a crime, and how the offer arrivesWithin a year of getting your number, someone will offer you money to be the RMO of a company you do not run, or ask you to pull a permit on a job you have never seen. The law calls the qualifier's duty supervision and control, and skipping it is a misdemeanor for you, discipline for the license, and a personal liability for every job done under your number. This lesson shows how the offer is worded, what the statutes actually say, and how to say no without burning the relationship.Current as of September 2026
- LessonOne name, everywhere: the business name, the DBA and the CSLB recordYour business has exactly one legal name for contracting purposes: the one on the CSLB record. The bond, the workers' compensation certificate, the contracts, the permits, the truck and the ads all carry that name, spelled that way. A DBA is allowed only if CSLB has it on file, it fits your entity type and classification, and the county has the fictitious business name statement. Changing the name later is a 90-day reportable event, and a change that creates a new entity means a new license number.Current as of September 2026
- CaseCase: three applicants, three delaysThree people pass the C-10 exams in the same week. One is a sole owner with a business name CSLB will not accept. One is the RMO of a corporation who did not know about the second bond. One files a workers' compensation exemption on a Friday and puts a helper on a job the next Monday. Each of them costs themselves weeks or worse, and each delay traces back to one rule from this phase. The names and details are illustrative; the rules are real.Current as of September 2026
Phase 1
Setting Up the Business
9 lessons
- LessonThe entity is a one-way door: the license belongs to it, not to youCSLB does not license you. It licenses a business entity, and the number is not transferable to any other person or entity under any circumstances. Incorporate later and the corporation applies for its own license; take on a partner and the partnership license is canceled when that partner leaves. This lesson lays out what each entity costs at CSLB before you ever get to taxes, so you choose once.Current as of September 2026
- LessonSole proprietor, LLC or S corporation: the tax side, with California's numbersA sole proprietor pays income tax plus 15.3% self-employment tax on the profit and has no state entity fees. A California LLC pays an $800 annual tax from its first year plus a fee that starts at $900 once California income passes $250,000, and at CSLB it carries a $100,000 bond and a $1,000,000 policy. An S corporation pays California 1.5% of net income with an $800 minimum, waived in the first year, and lets you split pay between salary and distributions. Here is how the three compare for a one-to-three-person electrical contractor, with the state's own numbers.Current as of September 2026
- LessonEIN, bank account, books: the plumbing under the businessBefore the first invoice: a free EIN from the IRS in minutes (never pay a website for one), a business bank account in the exact CSLB name, a card that touches nothing personal, and a bookkeeping habit that tracks every dollar to a job. The books are what turn an estimate into a price you can trust, what the CDTFA and FTB will ask for, and what makes the quarterly estimate a number instead of a guess.Current as of September 2026
- LessonThe city wants its own license: business tax certificates, and how Los Angeles taxes contractorsYour CSLB license lets you contract anywhere in California. It does not excuse you from the business license or business tax of the city you are based in, and often of the cities you work in. Los Angeles is the clearest example: a Business Tax Registration Certificate is mandatory, contractors pay $153 on the first $60,000 of gross receipts plus $1.01 per $1,000 above that, and a small business under $100,000 owes nothing only if it files the renewal on time. Here is how the city layer works and how to keep it from becoming a back-tax bill.Current as of September 2026
- LessonThe insurance stack: what the law requires, what the customer requires, and what actually protects youCalifornia requires two things of a sole-owner or corporate C-10: the $25,000 bond and workers' compensation (or a valid exemption). It requires general liability only of LLCs. Everything else, general liability, commercial auto above the state minimum, tools and equipment, umbrella, is demanded by the people who hire you, and by the arithmetic of one bad day. This lesson sets out each layer, who asks for it, and how to read the certificate a general contractor will demand before you set foot on the job.Current as of September 2026
- LessonSales tax for an electrical contractor: you are the consumer of wire and the retailer of light fixturesCalifornia treats you two ways at once. For wire, conduit, boxes and devices that disappear into the building you are the consumer: you pay sales tax to the supply house on your cost and charge the customer nothing labeled tax. For light fixtures, alarm fixtures, standby generators and switchgear that keep their identity, you are the retailer: you owe tax on the selling price and need a seller's permit. Getting this wrong in either direction is an audit finding; getting it right is a bookkeeping habit.Current as of September 2026
- LessonQuarterly estimates, self-employment tax, deductions and the mileage logNobody withholds tax from a contractor's checks, so the tax arrives four times a year and the government charges a penalty if you are late even when you end up owing nothing extra. A sole proprietor owes 15.3% self-employment tax on top of income tax, federal estimates are due in four equal installments, and California's are front-loaded 30/40/0/30. The 2026 business mileage rate is 72.5 cents per mile, but only with a log. Here is the set-aside percentage, the calendar, and the deductions an electrician actually has.Current as of September 2026
- TemplateTemplate: business setup checklist, from pass letter to first invoiceOne page, in the order the dependencies run: entity, name, CSLB issuance package, tax registrations, bank and books, insurance, city, first-job readiness. Each line carries the deadline that governs it and the lesson that explains it. Print it, tape it above the desk, and cross off in ink. The worked example beside it is a sole owner in Los Angeles going from pass letter to first invoice in five weeks.Current as of September 2026
- TemplateTemplate: insurance requirements matrix, one row per customer typeA single grid that answers the broker's first question and the general contractor's first demand: for each kind of customer you plan to serve, what coverage do they require, at what limits, with which endorsements, and what does the law require regardless. Fill the blank grid once, hand it to the broker, and price the whole stack in one quote. The worked example is a sole owner serving homeowners, two property managers and one general contractor.Current as of September 2026
Phase 2
Getting Work
10 lessons
- LessonWhere the first ten jobs come from, and what each channel needs from youThe first ten jobs do not come from a website. They come from six channels that already exist around a working electrician: the general contractors and property managers who know your work, the supply-house counter, home-warranty and solar companies that need a licensed sub in your area, realtors with inspection reports, and the neighbors of the first job. Each channel asks for a different thing before it will hand you work. Here is what each one wants, in the order you should knock.Current as of September 2026
- LessonThe supply house: pricing tiers, a trade account, and the preliminary notice your supplier will send your customerThe supply house is a bank, a sales office and a school. A trade account with net terms floats the materials on every job until the customer pays; the counter knows which general contractors are short an electrician; and the outside sales rep prices your big jobs. The part nobody explains: when you buy on credit for a job, your supplier may serve a preliminary notice on your customer, and the homeowner reads that a lien may be placed on their home even though they paid you. Set expectations before the letter lands.Current as of September 2026
- LessonAdvertising law: the license number on every ad, every contract and the side of the van, and the review habit that actually brings workCalifornia treats your advertising as part of the license record. The license number goes on every contract, bid and ad, and on the van in type at least three-quarters of an inch high. You may only advertise work in classifications you hold, so 'electrical and solar' is a misdemeanor for a C-10 alone. And the word 'bonded' is a ground for suspension. Get those four rules onto the van, the estimate and the Google Business Profile once, then spend the marketing energy where it pays: a review request at the end of every job.Current as of September 2026
- LessonPricing models: hourly, flat-rate price book, the service fee, and good / better / bestHow you price is a business model, not a habit. Hourly is honest and unprofitable on small jobs. A flat-rate price book gives the customer a number before you start, pays you for speed instead of punishing it, and produces the 'agreed contract amount in dollars and cents' that a home improvement contract must state. A service fee gets you paid for the diagnosis. Good / better / best lets the customer choose the level instead of arguing the price. Here is each model, its arithmetic, and where California's contract rules push you.Current as of September 2026
- LessonEstimating as a method: takeoff, labor units, materials, overhead recovery, markup versus margin, contingencyAn estimate is not a guess with a margin on top. It is six steps in a fixed order: take off the quantities, apply labor units to get hours, price the materials with tax and waste, recover overhead per billable hour, add profit as a margin on the selling price (not a markup on cost), and add a contingency sized to what you cannot see. Skip the overhead step and the job looks profitable until the truck payment. Confuse markup with margin and a 20% target quietly becomes 16.7%. Here is the method, with the arithmetic.Current as of September 2026
- LessonEstimate, quote or bid: what each word commits you to, and how the paper becomes a contractAn estimate is an approximation, a quote is a firm price for a defined scope for a stated time, and a bid is an offer that becomes a contract when accepted. Customers use the words interchangeably; the law does not. Under B&P 7151.2 a home improvement contract can be oral or spread across several documents, so the estimate you texted may already be part of the deal. Write every piece of paper as if it will be read in a dispute, because it will.Current as of September 2026
- LessonPublic works: DIR registration before you bid, prevailing wage over $1,000, and certified payroll every weekA school lighting retrofit, a city hall panel, an EV charger in a public parking lot: if public money pays for any part of it, it is public work. You cannot bid on it or perform it unless you are registered with the Department of Industrial Relations ($400 a year), you must pay the state prevailing wage on any project over $1,000, and you must keep certified payroll records under penalty of perjury. The small-project exception ($25,000 for construction, $15,000 for maintenance) lifts the registration requirement, not the prevailing wage. Here is the whole frame before you price your first public job at private rates.Current as of September 2026
- TemplateTemplate: estimate worksheet, six steps to a contract amountThe estimating method on one page: takeoff, labor units, materials with tax and waste, overhead per billable hour, margin by division, and a stated contingency, ending in the dollars-and-cents contract amount a home improvement contract requires and the maximum lawful down payment. The worked example prices a 200-amp like-for-like panel change in an occupied stucco home.Current as of September 2026
- TemplateTemplate: price-book starter, twenty tasks with the formula built inA price book is the estimating method pre-computed for the jobs you do every week: for each task, the labor unit, the material cost, the overhead and margin already applied, and the resulting flat price the customer hears before you start. The blank starter has the twenty most common C-10 residential tasks and the formula columns; the worked example fills in the numbers for a solo contractor and flags which lines are fixtures for the sales-tax line.Current as of September 2026
- TemplateTemplate: first-90-days marketing plan, names not categoriesNinety days, six channels, one page. The plan is a list of real names with a date beside each, a compliance row that gets the license number onto everything before the first message goes out, and a weekly scorecard that measures conversations and jobs, not clicks. The worked example is a solo contractor's actual first quarter: fourteen jobs from four channels, zero from ads.Current as of September 2026
Phase 3
Contracts and Getting Paid
19 lessons
- LessonThe home improvement contract: every element B&P 7159 requires, in the order it requires themAny residential job over $500 is a home improvement contract, and B&P 7159 dictates the form: specific headings in specific type sizes, seven notices with statutory wording, a signed copy in the customer's hands before work starts, and a Notice of Cancellation form in duplicate. Miss any of it and the contract is cause for discipline against your license. This lesson walks the statute top to bottom so the template in this phase makes sense line by line.Current as of September 2026
- LessonThe deposit cap and progress payments: $1,000 or 10%, never ahead of the workOn a home improvement contract the down payment may not exceed $1,000 or 10% of the price, whichever is less, and no other payment may run ahead of the work performed or materials delivered. That second rule is the one most electrical contractors break without knowing it: a 'materials deposit' for a panel that has not been delivered, or a 50% draw on a job that is 30% done, is a citation. The fix is a schedule of progress payments written from the job's real phases, and the discipline to invoice behind the work, never in front of it.Current as of September 2026
- LessonThe service and repair contract: the $750 short form, and the four conditions that keep it shortA dead outlet, a tripping breaker, a fan that hums: most service calls fit a short contract that skips the deposit schedule and the three-day cancellation wait. B&P 7159.10 allows it only when four things are true at once: the price is $750 or less, the customer called you, you fix only the problem they called about, and you collect nothing until the work is complete. Break any one and the job silently becomes a full home improvement contract with every notice from the last two lessons. Here is the form and where the line is.Current as of September 2026
- LessonSubcontracts with general contractors: pay-when-paid, retention, indemnity, insurance, and the notices that keep you paidWorking for a general contractor means signing their subcontract, and the subcontract is written to move risk downhill. Four clauses decide whether you get paid and when: the payment clause (pay-when-paid versus pay-if-paid), retention, indemnity, and insurance. California backs you with a seven-day prompt payment rule and a ten-day retention rule, but only your own 20-day preliminary notice keeps your lien and stop-notice rights alive on someone else's contract. Here is how to read the four clauses and what to send in the first twenty days.Current as of September 2026
- LessonChange orders: written, priced and signed before the extra work, or it is a giftBehind the drywall is where the contract price changes. California's answer is one sentence with three parts: a change order becomes part of a home improvement contract only if it is in writing and signed by the parties before the changed work begins, and it is unenforceable against the customer unless it states the scope, the dollar amount added or subtracted, and the effect on the payment schedule and completion date. Say it on the phone and do the work, and you are relying on the customer's goodwill for the money. Here is the two-minute habit that makes extras collectible.Current as of September 2026
- LessonMechanics liens, stop payment notices and payment bonds: the deadlines that decide whether you get paidA mechanics lien makes the property itself security for your unpaid bill, which is why it works when a lawsuit against a broke customer would not. It also dies on a calendar. As a direct contractor you record after completing your contract and before 90 days after the project is complete (60 if a notice of completion is recorded); as a subcontractor, 90 days, or 30 after a notice of completion, and only if your 20-day preliminary notice went out. Then you have 90 days to sue on the lien or it expires. Stop payment notices freeze money in the owner's hands; on public work, the payment bond replaces the lien. Here is the whole sequence with the dates.Current as of September 2026
- LessonThe four statutory release forms: conditional or unconditional, progress or final, and the one you must never sign before the check clearsCalifornia lets you sign away lien, stop notice and payment bond rights only on four forms whose text is written into the Civil Code: conditional or unconditional, on a progress payment or on final payment. A conditional release costs you nothing until the check clears. An unconditional release gives up the rights the moment you sign it, whether or not you are ever paid, and the form says so in capital letters. Homeowners are told in their own contract to demand releases; GCs demand them on every draw. Here is which form to sign when, and the one rule that has no exceptions.Current as of September 2026
- LessonCollections: the ladder from reminder to demand letter to lien to small claims, and when to hand it to a lawyerMost unpaid invoices are paid with a reminder. The rest move up a ladder with a date at each rung: a written demand citing the contract and the statutes, the preliminary notice and lien clock you already started, a stop payment notice if a GC is the problem, small claims for up to $12,500 if you are a sole proprietor or $6,250 for an entity, and a construction attorney for anything larger or anything involving a lien foreclosure. Two rules run through every rung: you must have been licensed the whole time, and you never threaten anything the statute does not let you do.Current as of September 2026
- LessonTaking payment: methods, timing, what a deposit is legally, and the final-payment handoffHow you take money decides how often you chase it. Card and electronic payment on the tablet at completion, deposits collected only within the cap and treated as the customer's money until the work is done, progress payments invoiced the day the milestone is real, and a final-payment handoff that trades the unconditional release for cleared funds. And no cash discount that skips the books: every dollar is income, every fixture sale is a sales tax event, and a deposit spent elsewhere is a disciplinary count.Current as of September 2026
- CaseCase: the unpaid job that lost its lien rightsA new C-10 corporation does the rough and finish electrical on a kitchen remodel for a general contractor, bills $14,200, and is paid $6,000. The GC stops answering. When the electrician finally learns what a preliminary notice is, the 20 days are long gone, the owner has paid the GC in full, and the remedy against the owner's property no longer exists. The names are invented; every deadline is real.Current as of September 2026
- CaseCase: the deposit that became a citationA sole owner sells a $12,400 service upgrade and EV circuit at the kitchen table, texts a one-paragraph 'estimate,' and takes a $4,000 'materials deposit' by card so the panel can be ordered. The job is finished, inspected and fine. Six weeks later a CSLB letter arrives anyway: the deposit exceeded the cap by $3,000, there was no compliant contract, no schedule, and the deposit was collected before any material was delivered. The customer never complained about the work. He complained about the paper. The names are invented; the statutes are not.Current as of September 2026
- CaseCase: the change order never writtenA sole owner on a $9,600 kitchen remodel finds aluminum branch wiring behind the wall, tells the homeowner it has to be dealt with, hears 'do what you have to do,' and spends two extra days and $1,900 in materials fixing it. At the final, the homeowner pays the contract price and disputes the extra. There is no signed change order, the release the homeowner asked for did not list the extra as an exception, and the contractor's only path to the $3,400 is a lawsuit on an equitable theory. The names are invented; the statute is quoted.Current as of September 2026
- TemplateTemplate: home improvement contract with every B&P 7159 notice verbatimA print-ready home improvement contract that carries every heading, statement and notice B&P 7159 requires, in the statute's own words and type sizes, with blanks for the job and a filled-in worked example for a 200-amp panel change. Type sizes are marked where the statute prescribes them: body 10-point, headings 10-point bold, the flagged statements 12-point bold. The statutory text is quoted verbatim and must not be edited.Current as of September 2026
- TemplateTemplate: service and repair contract ($750 or less, B&P 7159.10)A one-page service and repair contract for the small residential call: $750 or less, customer called you, you fix only what they called about, and you take no money until the work is done. Every heading and notice B&P 7159.10 prescribes is in place in the statute's words and type sizes, including the buyer-signed Notice to the Buyer and YOUR RIGHTS TO CANCEL BEFORE WORK BEGINS, plus the CSLB notice B&P 7030(b) requires. Beside the blank is a filled-in example for a tripped GFCI and a dead kitchen circuit.Current as of September 2026
- TemplateTemplate: change order (the two-minute form that keeps the extra)A one-page change order for a home improvement contract that puts the three statutory elements where the customer signs: scope of the change, amount added or subtracted, and the effect on the progress payment schedule and completion date. It carries the subcontractor disclaimer B&P 7159 requires on every change order, runs a new contract total, re-checks the down payment cap against that total, and has the customer sign before the changed work starts. Beside it, the aluminum-wiring change order from the Phase 3 case, written the way it should have been.Current as of September 2026
- TemplateTemplate: California preliminary notice (20-day notice) with proof of serviceA fill-in California preliminary notice for the electrical subcontractor working under a general contractor, with every item Civil Code 8102 and 8202 require, the NOTICE TO PROPERTY OWNER statement in the statute's words, a proof of notice declaration that matches Civil Code 8118, and a service log for the three people who must receive it. Beside it, the notice from the Phase 3 case of the unpaid kitchen remodel, served on day 6 instead of never. The notice is not a lien and does not accuse anyone of anything; it preserves the right to record one.Current as of September 2026
- TemplateTemplate: the four California lien waiver and release forms (Civil Code 8132 to 8138)All four California statutory waiver and release forms, reproduced from Civil Code 8132, 8134, 8136 and 8138 with the one-sentence rule for choosing among them: conditional when you have not been paid yet, unconditional only after the money has cleared; progress while the job is running, final at the end. Beside each blank form is the same form filled in for one job, so you can see the Through Date, the check details and the Exceptions lines carry the numbers that protect you. A release in any other wording is void, and an unconditional release signed before the money clears is enforceable against you anyway.Current as of September 2026
- TemplateTemplate: payment demand letter (to a general contractor, and to an owner)Two one-page demand letters that say exactly what is owed, why, by when, and what the statute provides if it is not paid, with nothing added. Letter A is from a subcontractor to a general contractor for a late progress payment or retention and cites B&P 7108.5 and Civil Code 8814 and 8818. Letter B is from a contractor to a homeowner for a completed progress payment under a home improvement contract and cites the contract's own schedule and Civil Code 8800. Each is served the way the statute recognizes and dated against the lien and stop payment notice deadlines so the letter is a step, not a substitute. Beside each is the letter from a Phase 3 case, filled in.Current as of September 2026
- TemplateTemplate: subcontract review checklist (yes / no / fix, before you sign a GC's form)A two-page checklist to run on any general contractor's subcontract before you sign it: twenty-six questions across payment, retention, lien rights, scope, schedule, changes, indemnity, insurance, flow-down, termination and the paperwork you owe in the first twenty days. Each line has a yes / no / fix column and the statute that backs your ask where there is one. Beside it, the checklist completed on a real-shaped GC form for a tenant-improvement job, with the three changes the electrician asked for and got, the one she priced instead, and the two she declined to sign.Current as of September 2026
Phase 4
The Field: Method and Cases
30 lessons
- LessonThe diagnostic method: one way to work every call, from the complaint to the options sheetEvery call in this phase runs on one method: verify the complaint in the customer's words, isolate the circuit or system, run the cheapest test first (voltage, then continuity, then load), find the cause instead of the symptom, lay out an options ladder (repair, replace the section, replace the system) with a cost band, a permit path and a code trail for each rung, then document and communicate. The method is what makes a new contractor look like an experienced one, and it is also how the safety orders expect the work to be done: de-energize, lock and tag, test before touch, and treat energized work as a supervised exception.Current as of September 2026
- LessonPermits and inspections: what needs one, the four exemptions, and how to pass rough and final the first timeIn California housing, a written permit is required before you install, alter or reconstruct any electrical system, and the code names exactly four things a local department must exempt from permit and inspection: plug-in temporary decorative lighting, reinstalling a receptacle (not the outlet), replacing a breaker of the same rating in the same location, and communications wiring. Everything else, from a new circuit to a panel change, is permitted and inspected at rough and final, and the work stays open until it is approved. Two state laws ride along on residential permits: smoke alarms must be State Fire Marshal listed before the department will sign off on any job over $1,000, and existing homes with gas appliances, a fireplace or an attached garage must have carbon monoxide alarms. Skipping permits is a licensing case, not a paperwork problem.Current as of September 2026
- LessonDaily-use code: box fill, conductor sizing, overcurrent protection, AFCI and GFCI, tamper-resistant receptacles, working clearance, grounding and bondingThe eight code questions you answer on almost every residential job, with the section numbers and the numbers themselves: how many conductors fit in a box (314.16), what wire a breaker allows and what ampacity a service needs (240.4(D), 310.16, 310.12), where AFCI and GFCI protection is required in a dwelling (210.12, 210.8), which receptacles must be tamper-resistant (406.12), how much clear space a panel needs and where it may not go (110.26, 240.24), and how the grounding electrode system and the bonding are built and sized (Article 250). Written from the 2025 California Electrical Code, which is the 2023 NEC with California amendments, in force since January 1, 2026. Paraphrased, with the section to read beside each rule.Current as of September 2026
- LessonLoad calculations (Article 220): sizing a dwelling service, and what an EV charger or a heat pump addsHow to size a dwelling service the way the code and the inspector expect: the standard method of Article 220 Part III, the optional method of 220.82 that most residential contractors use, the two ways the code lets you prove an existing house can take a new load (220.83 and the 220.87 utility-data method), and the 2023 edition's rule that an EV charger counts at 7,200 volt-amperes or its nameplate, whichever is larger. A worked 1,800-square-foot house runs the numbers with and without a 40-amp EV circuit and shows why a 100-amp service that was fine for thirty years is not fine the day the car arrives. Ends with the California readiness rules that decide how big the panel has to be on new work.Current as of September 2026
- LessonService upgrades and panel changes: 100 to 200 amps, the meter and main, utility coordination, working clearance, and the two panel brands you will be asked to replaceThe service upgrade is the most common large residential job a new C-10 sells, and it is a coordination job as much as an electrical one: the load calculation that justifies it, the utility's service planning process and the disconnect and reconnect appointment, the meter-main or meter socket and panel combination the utility will accept, the 2/0 copper or 4/0 aluminum conductors the code requires for 200 amperes, the outdoor emergency disconnect now required on one- and two-family dwellings, the working clearance that fails more inspections than any wiring error, the grounding electrode system you almost always rebuild, and the California rules that ban reconditioned panelboards and, on new work, set the busbar at 225 amperes for battery-ready homes. It closes with the two panel brands, Federal Pacific Stab-Lok and Zinsco, that customers will ask you about and how to answer honestly.Current as of September 2026
- LessonEV charger installs: Article 625, the load calc, load management, permits, and the California readiness rulesThe Level 2 charger is the most requested new circuit in California, and it is a load-calculation job first: the 2023 edition counts every EVSE at 7,200 volt-amperes or its nameplate, whichever is larger, which is what pushes a full 100-amp house over the line. Then Article 625: an individual branch circuit, an overcurrent device at 125 percent of the charger's continuous load (a 48-amp hardwired unit needs a 60-amp breaker and 6 AWG copper), GFCI protection on any receptacle installed for a plug-in charger, and the option the code gives you when the service is tight, a listed energy management system that caps the charger under 625.42. The permit is a nondiscretionary building permit by state law; the California readiness rules say what new houses already have in the wall.Current as of September 2026
- LessonSolar and storage: Articles 690, 705 and 706, rapid shutdown, Rule 21 interconnection, the Net Billing Tariff, and where the batteries can goSolar work for a C-10 is three jobs in one: the code job (Articles 690, 705 and 706: rapid shutdown, the disconnects and labels, the point of connection and the 120 percent busbar rule, and the energy storage rules), the utility job (a Rule 21 interconnection application to the investor-owned utility, and permission to operate before the system exports), and the customer conversation, which since April 15, 2023 is about the Net Billing Tariff: exports are credited at their value to the grid, not at retail, which is why nearly every new system is sold with a battery. Storage brings its own rules for where the batteries may sit. The permit is nondiscretionary by state law and most jurisdictions run a checklist process; the interconnection is what takes the time, and the case in this phase is a system that sat finished for four months waiting for it.Current as of September 2026
- LessonTroubleshooting: dead circuits, tripping breakers, flicker and the loose neutral, voltage drop, and multiwire branch circuitsFive complaints make up most troubleshooting calls, and each has a tree: a dead circuit (find where the voltage stops), a tripping breaker (overload, short, ground fault, arc fault or a failed breaker, and each has a different test), flicker (almost always a loose or open neutral, and dangerous when it is the service neutral), voltage drop (a long run or a bad connection, measured under load), and the multiwire branch circuit with a lost neutral that puts 240 volts across 120-volt equipment. The lesson gives the test order for each, the code sections that decide the fix, and the one rule under all of it: voltage testing is done live with the safeguards the safety orders require, and everything else is done on a locked and tagged circuit.Current as of September 2026
- LessonOlder homes: aluminum branch wiring, knob-and-tube, ungrounded receptacles and the GFCI replacement rules, and cloth wiringFour things you will find in the walls of a California house built before 1980, and what the code and the federal safety agency say to do about each: aluminum branch wiring, which the Consumer Product Safety Commission says has only three acceptable permanent repairs, none of which is the pigtail-with-a-wirenut most electricians were taught; knob-and-tube, which California allows under insulation only after a licensed electrical contractor surveys it and files a certification; ungrounded two-prong receptacles, which may be replaced with a GFCI or a GFCI-protected grounding receptacle carrying the exact markings 406.4(D)(2) prescribes; and cloth-insulated wiring, which is a condition to inspect, not a code violation by itself. Each becomes a rung on the options ladder with an honest cost band.Current as of September 2026
- LessonTitle 24 energy code for the electrician: high-efficacy lighting, JA8, sensors and dimmers, outdoor controls, and the readiness circuitsTitle 24, Part 6 is the energy code, and for a residential electrician it is mostly a lighting code with a set of readiness circuits attached. The 2025 edition, which applies to permit applications filed on or after January 1, 2026, says: every installed luminaire and light source is JA8-certified and marked; recessed cans have no screw bases, are airtight and gasketed; every room has a manual on-off switch; bathrooms, garages, laundry rooms, utility rooms and walk-in closets get an occupancy or vacancy sensor that turns lights off; living rooms, dining rooms, kitchens and bedrooms get dimmers; undercabinet lighting is switched separately; and outdoor fixtures on the house need a photocell plus a motion sensor or a time switch, or an astronomical clock, with overrides that reset within six hours. On new work the panel also carries the heat pump, cooktop, dryer and battery readiness circuits the Electrical Code now points to. Knowing this is what keeps a kitchen remodel from failing its final on a $12 switch.Current as of September 2026
- LessonGenerators, transfer switches, interlocks and backup power: Article 702 and how to sell backup honestlyBackup power in a California house is one of four things: a portable generator on a cord with a listed inlet and interlock, a standby generator with an automatic transfer switch, a battery system with its own transfer equipment, or a whole-house arrangement that combines them. Article 702 governs all of it as an optional standby system, and its rules are short and unforgiving: the standby source must never be able to connect to the utility at the same time (702.5), the system must carry the loads the customer will actually put on it (702.4), a sign at the service must say what kind of standby source there is and where (702.7), and the generator's own disconnect, receptacle GFCI and grounding rules in Article 445 and 250.30 apply. The suicide cord and the unlisted breaker interlock are the two things you will be asked to install and must not. New California homes come battery-ready, which changes the estimate.Current as of September 2026
- LessonScope and licensing: C-10 versus C-7 and C-46, low voltage, data and AV, incidental work, and what requires which licenseYour C-10 covers anything that generates, transmits, transforms or uses electrical energy, at any voltage, which is why the C-7 low-voltage license is defined by what it cannot touch (anything over 91 volts, and fire alarm systems) and the C-46 solar license by what it cannot do (other trades except as needed for the solar system). The lesson draws the lines that matter on a residential job: data, AV and low-voltage lighting are inside the C-10 and also available to a C-7; fire alarm is C-10; a solar array is either license, but the service upgrade and the storage interconnection are yours; the drywall patch and the trench are incidental only when they are small and necessary to your electrical work; and a general building contractor may not take a single-trade electrical job as a prime unless it holds a C-10 or subs it to one. Working outside your classification is a disciplinary cause by itself, and so is hiring a sub who is not licensed for what you hired them to do.Current as of September 2026
- LessonElectrical safety on your own jobs: Cal/OSHA's electrical orders, lockout and tagging, arc flash and PPE, ladders near lines, the IIPP every employer must have, and heat illnessThe day you hire your first helper, two documents become mandatory: a written Injury and Illness Prevention Program with eight elements Cal/OSHA spells out, and a heat illness prevention plan in English and the language your crew speaks. Before that day, the Electrical Safety Orders already govern how you work: only qualified persons on electrical equipment, energized work only when supervision has decided it is necessary with insulated gloves above 250 volts and flame-resistant clothing, lockout and tagging with a tag that names the reason, the person and the date, a 6-foot rule near high-voltage lines, and a fiberglass ladder anywhere you might touch a conductor. Arc flash is the hazard the code itself sends you to NFPA 70E to understand. This lesson is the safety program of a small electrical contractor in one place, and the IIPP and heat plan templates in this phase are its paperwork.Current as of September 2026
- LessonMaterials and methods: NM, MC and EMT, where each is allowed, how each is supported and protected, and the California amendment that decides itThree wiring methods do almost all residential and light-commercial work in California, and the code tells you exactly where each may go. Nonmetallic-sheathed cable (NM) is allowed in one- and two-family dwellings and in multifamily and other buildings of wood-frame construction types, concealed behind a fifteen-minute thermal barrier outside of dwellings, and only inside raceways in noncombustible Type I and II buildings; the California amendments print that rule and tie the construction types to the Building Code. Metal-clad cable (MC) goes almost anywhere NM cannot, including exposed and in commercial ceilings. Electrical metallic tubing (EMT) is the method for exposed work, wet locations with the right fittings and anywhere subject to damage. The lesson gives the uses-permitted and not-permitted lists, the support intervals (NM every 4½ feet and within 12 inches of a box; MC every 6 feet; EMT every 10 feet and within 3 feet of a box), the 1¼-inch nail-plate rule, and the local-amendment check that decides whether your city allows NM at all.Current as of September 2026
- LessonCommercial basics: three-phase systems, motor circuits, panel schedules, tenant-improvement lighting retrofits, and the labels commercial work requiresThe first commercial call is usually small (a tenant improvement, a motor that will not start, a lighting retrofit) and it is a different world in four ways: the power is three-phase, so voltages, neutrals and the high-leg marking are new; motor circuits are sized from the code's tables and three separate rules, not from the nameplate alone; every panel needs a legible schedule and, on commercial gear, an arc-flash warning label; and the lighting is governed by the nonresidential half of the Energy Code, which puts a certified acceptance test technician between you and the final. The contract changes too: the residential home-improvement rules of Phase 3 do not apply, and the 10-point CSLB notice of B&P 7030(a) goes on every prime contract. This lesson is the vocabulary and the section numbers for the first year of commercial work.Current as of September 2026
- LessonEnvironmental: the EPA lead renovation rule for every pre-1978 home, and asbestos before you cut into an old ceilingTwo federal and state rules follow you into any house built before 1978: the EPA's lead renovation rule, which requires your firm to be EPA-certified and your people trained as certified renovators before you disturb more than six square feet of painted surface in a room (or twenty outside), with the Renovate Right pamphlet handed over first and the lead-safe work practices used; and the asbestos rules, under which the air district requires an asbestos survey before renovation in the South Coast basin, Cal/OSHA's construction standard governs any disturbance, and a contractor doing 100 square feet or more of asbestos work must be registered with Cal/OSHA. An electrician cutting boxes into old plaster, pulling a popcorn ceiling for cans, or opening an old panel wall is inside both rules more often than not. The lesson gives the thresholds, the paperwork and the estimate line.Current as of September 2026
- LessonJob-site craft: sequencing with the other trades, protecting the home, the daily close, and the punch list that ends the jobThe code's only sentence about craft is that work be done in a neat and workmanlike manner with the equipment protected from paint, plaster and debris, and it is enforced every day by inspectors, general contractors and customers who decide whether to call you back. This lesson is the working habits behind that sentence: where the electrician fits in the sequence of a remodel and what has to be true before you start each phase, how to protect a lived-in house so that the customer's memory of the job is the work and not the dust, the ten-minute close that ends every day, and the punch list that ends the job with the final payment earned, the change orders signed, the panel labeled and the photographs taken.Current as of September 2026
- CaseCase: the panel upgrade that failed inspection on working clearanceA new C-10 replaces a 100-amp panel with a 200-amp meter-main in the same spot on the side of a 1958 house, does clean work, and fails the final because the water heater platform the homeowner built two years earlier leaves 27 inches in front of the new equipment instead of the 36 the code requires. The utility will not reconnect without the inspector's release, the house is on a generator for three days, and the fix is a relocation that was visible at the site visit. The names are invented; the dimensions come from the code.Current as of September 2026
- CaseCase: the AFCI that would not stop trippingTwo electricians before her had replaced the bedroom AFCI breaker, twice, and the third one tripped within a week like the others. Marisol Tran runs the method instead of the parts counter: verifies, isolates, tests dead, and finds two 1978 bedroom circuits sharing one neutral in a ceiling box, wired by a previous owner, so that the AFCI sees the other circuit's return current as a fault and trips exactly as designed. The fix is a wiring repair, the code makes it a two-pole breaker or a handle tie with grouped conductors, and the whole call fits inside a $750 service and repair contract. The names are invented; the fault is the most common one there is.Current as of September 2026
- CaseCase: the EV charger on a 100-amp serviceA handyman-turned-contractor hangs a 48-amp hardwired charger on a 60-amp breaker in a full 100-amp panel, no permit, no load calculation, and the main breaker trips at dinner the first night the car charges. The homeowner calls Priya Natarajan, who runs the Article 220 numbers on the kitchen table and works three honest rungs: a 200-amp service upgrade, a charger turned down behind a listed load-management system, and the utility's twelve months of demand data under 220.87 to see whether the house is really as full as the paper says. On this house the code's 7,200 volt-ampere floor for any EVSE means only the upgrade closes, the homeowner picks it, and the charger stays de-energized and tagged until the service can carry it. The names are invented; the arithmetic is the code's.Current as of September 2026
- CaseCase: the aluminum-wiring flipAn investor flipping a 1970 house wants the aluminum branch wiring 'taken care of' for the buyer's inspection, cheap and fast: pigtail every device with twist-on connectors, no permit, be done Friday. Omar Haddad, C-10, says no to the method the federal safety agency calls not a permanent repair and no to the missing permit, and offers the two rungs CPSC recognizes with real prices: AlumiConn connectors at every connection under a permit with AFCI on the modified circuits, or a copper rewire. The investor hires someone else. Nine months later the buyer's attorney calls Omar as a witness. The names are invented; the CPSC position is quoted.Current as of September 2026
- CaseCase: the solar interconnection that took four monthsA 7.2-kilowatt rooftop system with a battery is installed in four days and does not export for four months, and every one of the delays is paperwork: a single-line diagram that showed a different inverter than the one on the wall, an inverter model not on the utility's approved list, a customer authorization signed by the wrong spouse, an inspection release the contractor forgot to upload, and a meter change appointment missed because nobody told the customer. The customer's contract promised 'completion' in six weeks, the final payment was tied to permission to operate, and the contractor floated $14,000 for a season. The names are invented; the process is Rule 21's.Current as of September 2026
- CaseCase: the customer who doesn't want a permitA homeowner wants a subpanel and six circuits for a garage workshop, has a quote from someone who will do it without a permit for $900 less, and asks Andre Petrosyan to match it. Andre does not argue; he says the one sentence the statute gives him, hands over the options sheet with the permit fee as a line item, and explains what the customer is actually buying with the fee: an inspector's signature that follows the house. The customer hires the other guy. Two years later the house is in escrow, the buyer's inspector finds the unpermitted subpanel, and the seller's agent calls Andre to 'legalize' it. The names are invented; the sections are real.Current as of September 2026
- CaseCase: the energized-conductor call and the walk-awayA restaurant owner calls at 6 p.m. on a Friday: a 480-volt panel in the kitchen is buzzing, one of the walk-in coolers is dead, the dinner rush is starting, and 'you can't shut anything off.' Sam Okafor arrives, reads the arc-flash label, sees a failed breaker with a heat-damaged bus, and is told by the owner, the manager and the cook that the power stays on while he fixes it. He says no, explains the two lawful paths (a lockout of that panel section during a break, or a scheduled shutdown), and when the owner refuses both, he documents the hazard, hands over a written finding, and leaves without a fee. The owner calls back Monday. The names are invented; the safety orders are quoted.Current as of September 2026
- TemplateTemplate: job-site checklist (arrival, safety, protection, daily close)A one-page checklist you run on every job, in four blocks: arrival (permit, contract, scope, year built, who is home), safety (lockout kit, gloves, ladder, water and shade, the two Cal/OSHA documents if anyone works for you), protection of the home (paths, dust, the panel taped shut, the pre-1978 lead rule), and the daily close (power restored, openings covered, photos, tomorrow's plan). Each line carries the section that makes it a rule where there is one. Beside the blank, the same checklist filled in for a two-day kitchen circuit job in a 1962 house with a helper on site in July.Current as of September 2026
- TemplateTemplate: pre-inspection checklist by stage (rough, service, final)Three checklists, one per inspection, walking the items a California residential inspector looks at in the order they look: at rough, boxes, fill, support, protection, the AFCI and GFCI plan, the panel location and the grounding electrode system; at a service change, conductors, disconnects, clearances, grounding and labels; at final, devices, tamper-resistant and GFCI, breakers against wire, the directory, the alarms the state requires and the Energy Code's lighting controls. Each line has the section number so a correction can be read and answered. Beside the blank, the checklists filled in for a 200-amp service change plus a kitchen remodel, with the two items that would have been corrections caught the day before.Current as of September 2026
- TemplateTemplate: dwelling load calculation worksheet (optional method, existing-dwelling method, EV and heat pump)A one-page worksheet that produces the number the permit application asks for, by the code's own methods: the optional method of 220.82 for a new or fully known house (general loads at 100 percent of the first 10 kVA and 40 percent of the rest, plus the largest of heating or cooling), the existing-dwelling method of 220.83 for adding load to an old house, and the utility-data method of 220.87 (twelve months of maximum demand at 125 percent plus the new load). The EV line carries the 2023 edition's 7,200 volt-ampere floor. Beside the blank, the worksheet filled in for a 2,100-square-foot house adding a heat pump and a 40-amp EV circuit, run all three ways.Current as of September 2026
- TemplateTemplate: Injury and Illness Prevention Program starter for a small electrical contractor (8 CCR 3203)The written program every California employer must have from the first hire, built element by element from Cal/OSHA's own list in section 3203: who is responsible, how compliance is ensured, how safety is communicated, how hazards are found (with the scheduled inspections), how injuries are investigated, how hazards are corrected, when training happens, and how employees get a copy. Written for a one-truck electrical shop with one to nine employees, using the small-employer exceptions the regulation allows, with the electrical safe practices (lockout, energized work, ladders, overhead lines) written in as the shop's rules. Beside the blank, the program filled in for a two-person shop the week it hired its first helper.Current as of September 2026
- TemplateTemplate: heat illness prevention plan for an electrical contractor (8 CCR 3395), English and Spanish on one sheetA one-sheet plan that contains the four elements Cal/OSHA's heat standard requires in writing (water and shade procedures, high-heat procedures, emergency response, acclimatization), written for the way an electrician actually works: attics in August, garages with the door down, roofs for solar, and a helper on their first week. The numbers are the regulation's: a quart of water per person per hour, shade when it passes 80 degrees, the 95-degree procedures with a ten-minute cool-down every two hours, five-minute minimum rests, 14-day observation for new workers. The plan must be in English and the language of the majority of your employees; this template prints both. Beside the blank, the plan filled in for a two-person shop working an attic rewire in the Central Valley.Current as of September 2026
- TemplateTemplate: customer options sheet (findings, the three rungs, permit path, code trail, what you chose)The one page you leave with every customer after a diagnosis: what you found, in their words and yours, with a photograph reference; the three rungs of the options ladder (repair, replace the section, replace the system), each with a cost band, whether a permit is required and why, the code sections the work must meet, and what each rung does not fix; and a signature line for the rung the customer chose, which becomes the change order or the new contract. It is the method's step 5 and step 7 on paper, and it is written so a customer can hand it to a spouse or a second contractor and be understood. Beside the blank, the sheet filled in for a dead kitchen circuit that turned out to be a shared neutral in a 1978 house.Current as of September 2026

Customers, Warranties, Complaints
11 lessons
- LessonPresenting options and price without apologizing, and what to say when the other guy is cheaperThe price conversation is the last five minutes of the diagnostic method, and most new contractors lose it by explaining, discounting or apologizing. This lesson gives the four-line presentation that works (what we found, the three rungs, the price of each in the contract's own form, and which one we recommend and why), the reasons a price is a price (the schedule of progress payments, the deposit cap and the license number are on the paper for a reason), and the three honest answers to the other guy is cheaper: ask what the other quote includes, name the three things a lower quote usually leaves out (the permit, the code items, the paper), and let the customer choose without a fight. Also: the four things you never say, and how to hold a price you know is right.Current as of September 2026
- LessonDelivering bad news: the finding behind the wall, the failed inspection, the delay, and the price that has to changeFour pieces of bad news arrive on almost every remodel: the concealed condition that changes the price, the inspector's correction, the schedule slip, and the discovery that something the customer wanted is not allowed. New contractors deliver them late, by text, with an apology attached, and the customer hears a contractor who is not in control. This lesson gives one structure for all four (fact, cause, options, what happens next, in that order, in person or by phone the same day), ties each to the contract law that governs it (a change order before the work, the completion date on the contract, the code the inspector is enforcing), and covers the two things you never do: eat the cost silently to avoid the conversation, or walk off the job.Current as of September 2026
- LessonHow long you are on the hook: the four-year and ten-year windows at CSLB and in court, and what they mean for your filesEvery contract you sign tells the customer, in the CSLB's own words, that they can complain within four years about anything they could see and within ten years about structural defects they could not. Those numbers are real: B&P 7091 sets them for CSLB complaints, the Code of Civil Procedure sets the same four and ten years for lawsuits over patent and latent construction defects, and the Right to Repair Act gives new-home electrical work a four-year standard from close of escrow inside a ten-year outer limit. This lesson explains what patent and latent mean for an electrician, why the ten-year window rarely reaches electrical work but the four-year one always does, how the contractor's bond fits, and the one practical consequence: your job files, photographs and permits are evidence for at least four years and, for structural work, ten.Current as of September 2026
- LessonA warranty policy that protects you: what to promise, what to exclude, how long, and how to honor it without losing moneyNo statute writes an electrical contractor's warranty, so most new contractors either promise nothing in writing, which customers read as hiding something, or promise everything for life, which is a lawsuit with a signature. The policy that works is one page: what is covered (your workmanship), for how long (a year is the common floor and a defensible choice), what is not (manufacturer's parts beyond the manufacturer's warranty, damage by others, changes in use, nuisance trips that turn out to be the customer's appliance), how to make a claim, and what the warranty is not (it does not shorten the four-year complaint window, and it does not replace the code). This lesson gives the reasoning behind each line of the template in this phase, the two warranty calls every electrician gets (the GFCI that trips and the breaker that trips), and how to honor a warranty call so that it makes you money in referrals instead of costing you a day.Current as of September 2026
- LessonThe CSLB complaint process from the contractor's side: the letter, mediation, investigation, arbitration, citations, and what becomes publicOne day a letter from CSLB arrives with a case number and a customer's name. What happens next is a process with steps you can see coming: a review for jurisdiction, a notice inviting you to resolve it, possible mediation, a referral to small claims and your bond for small disputes, an investigation for the rest, arbitration if the criteria fit, and, for violations proven by clear and convincing evidence, a citation with an order of correction and a civil penalty, or an accusation prosecuted by the Attorney General. This lesson walks each step from the contractor's chair, with the statute under it: what the investigator will ask for, how to respond in writing without making it worse, when the arbitration programs apply and what an unpaid award does to your license, what a citation costs since July 2026, and exactly what the public sees on your license record and for how long.Current as of September 2026
- LessonReviews and reputation: asking for them, answering the bad one, and the two laws that decide what you may and may not doReviews are the second public record on your business after the CSLB license lookup, and the only one you can shape. This lesson gives the routine that produces honest five-star reviews (ask at the moment of the finished punch list, make it easy, never pay for sentiment), the three-paragraph answer to a bad review that wins the next customer instead of the argument, and the two laws that draw the lines: California's Civil Code 1670.8, which voids any contract clause that stops a customer from reviewing you and fines the contractor who threatens one, and the FTC's 2024 rule on consumer reviews, which makes fake reviews, paid-for sentiment, undisclosed insider reviews and review suppression unfair or deceptive practices. Also: why the license number goes on the review profile, and how reviews and the CSLB record read together.Current as of September 2026
- LessonWalking away from the wrong customer and ending a job lawfully: abandonment, the stop work notice, and the three exits the law allowsSome customers should not be yours, and some jobs have to end before the work does. The license law is strict about how: abandoning a project without legal excuse is a disciplinary cause, and so is failing to complete for the contract price. But the law also provides three lawful exits, and this lesson walks each: declining before you sign (the free one, and the one to use most), the mutual written termination or change order that reduces the scope by agreement, and the stop work notice, a statutory procedure that lets a direct contractor stop for nonpayment without becoming liable for the delay. It ends with the four customer signals that predict a bad job, and the walk-away conversation for the request you must refuse: the no-permit job, the energized work, the code violation the customer insists on.Current as of September 2026
- CaseCase: the complaint that arrived three years laterThirty-nine months after a kitchen remodel, a letter from CSLB: the former customer, now selling the house, alleges the electrician's work was substandard and unpermitted because the buyer's inspector found a bootleg splice in the attic and a bedroom circuit without AFCI protection. Camila Reyes opens the job file the same afternoon: the signed contract with the 7159 notices, the permit and final inspection record, the change order the customer signed for the two attic circuits, 84 photographs including the one of the AFCI breaker she installed, and the options sheet on which the customer declined to correct a pre-existing splice she had documented in a different part of the attic. The complaint closes at the notice stage without a finding, and nothing appears on her license. The names are invented; the process is CSLB's.Current as of September 2026
- CaseCase: the one-star review and the gag clauseA new contractor inherits a contract form from the company he used to work for, including a terms-and-conditions page with a clause charging $2,500 to any customer who posts a negative review. When a customer posts a one-star review over a two-week inspection delay, he sends her the clause and an invoice. She sends both to a consumer attorney. The clause is void under California law, the threat itself is unlawful, and the same conduct is an unfair practice under the federal review rule. The case follows the letter he receives, what it costs, the three-paragraph reply he should have posted instead, and the audit of every inherited form that follows. The names are invented; the statutes are quoted.Current as of September 2026
- TemplateTemplate: workmanship warranty statement (one page, attached to the contract)A one-page warranty statement that promises exactly what a small electrical contractor can keep: one year on workmanship from final inspection, the manufacturer's warranty on devices with your help making the claim, a written list of what is not covered, a claims procedure with a response time you can meet, and a plain-language paragraph saying the warranty does not limit the customer's rights under California law, including the right to complain to CSLB within the statutory period. It contains no gag clause and no consequential-damages promise. Beside the blank, the statement filled in for a 200-amp service upgrade with a two-year workmanship term the contractor's price book supports.Current as of September 2026
- TemplateTemplate: written response to a CSLB complaint (facts in order, numbered exhibits, an offer)The letter you send CSLB in the days after the notice arrives, built for the reader who will decide whether the complaint closes at the notice stage or moves to an investigator: your license and the case number; whether the complaint is within the four-year window; the facts in date order with a numbered exhibit beside each one (contract, change orders, permit and inspection record, photographs, options sheet, invoices, the customer's own messages); a paragraph answering each allegation by pointing at an exhibit; and, where it makes sense, a specific offer with a price, a document and a date, without admitting anything. No adjectives, no history of the customer, nothing you cannot attach. Beside the blank, the letter Camila Reyes sent in the three-years-later case.Current as of September 2026

- LessonYour first helper: why almost everyone you pay to pull wire is an employee, and the one way a subcontractor is notThe day you cannot do it alone, the question is not 'employee or 1099?' California already answered it. Anyone you pay to help with electrical work is an employee unless you can prove all three parts of the ABC test, and part B, that the work is outside your usual course of business, fails for a helper pulling wire for an electrical contractor by definition. The only route to a lawful non-employee on your jobs is a real subcontractor: a business with its own CSLB license, its own contract with you in writing, its own shop, its own insurance and the power to hire its own people. This lesson walks the test, the construction exception in Labor Code 2781, the older rule in 2750.5 that an unlicensed person doing licensed work can never be an independent contractor, and the price of guessing wrong: $5,000 to $25,000 per violation, an order sent to CSLB, and a disciplinary case the Board must open within 30 days.Current as of September 2026
- LessonWho may touch the wire: state electrician certification, the trainee route, apprentices, and what an inspector asks your crew forCalifornia is one of the states where the person on the ladder, not only the company, must be credentialed. Anyone who performs work as an electrician for a C-10 contractor must hold a state certification card, be a registered apprentice in an approved program, or be a registered electrician trainee enrolled in an approved school and supervised one-to-one by a certified electrician. The qualifying person on the license is the exception. This lesson gives the definition that triggers the rule (connecting electrical devices, above 100 volt-amperes), the five certification categories and the hours to sit each exam, what the card costs and how it renews, the trainee path a new hire can start on this month, where apprentices fit, and the enforcement mechanics: a Labor Commissioner referral, a CSLB investigation that must open on receipt, and a presumption of violation the moment your crew cannot produce evidence on site.Current as of September 2026
- LessonPayroll and the wage-and-hour rules: minimum wage, overtime, meals and rest, paydays, pay stubs, sick leave, final pay, and the notice you owe at hirePayroll in California is a set of exact numbers and deadlines, and a helper who knows them better than you do can turn a good year into a wage claim. This lesson puts the current rules in one place, each with its section: the $16.90 state minimum (higher in many cities), overtime after eight in a day and 40 in a week with double time after twelve, the 30-minute meal before the end of the fifth hour and the paid 10-minute rest per four hours under the construction wage order, the twice-a-month payday windows, the nine items every pay stub must carry, paid sick leave that starts accruing on day one, the same-day final check for someone you let go and the 72-hour check for someone who quits, the written notice you hand every new hire, and the 2026 employer-side tax rates to load into your price book. It closes with what each mistake costs, which is the reason to run payroll through a service from the first hire.Current as of September 2026
- LessonBecoming an employer in thirty days: the workers' compensation switch, the EDD account, the new-hire report, the I-9, and the order to do them inBetween the handshake and the first paycheck there are six filings with four agencies, and the order matters because one of them can suspend your license the day you get it wrong. This lesson puts them in sequence: workers' compensation coverage bound and the certificate filed with CSLB before the first hour of work, because the no-employee exemption dies the moment you have an employee and employing on an exemption is a $10,000 minimum penalty; the EDD employer account within 15 days of paying more than $100 in a quarter; the I-9 within three business days of the first day; the new-hire report within 20 days; state withholding from the first check; and the written injury prevention program and hire notice that must already exist. It also gives the price of not insuring at all: a misdemeanor with a fine of at least $10,000, a stop order, and $1,500 per employee or double the premium.Current as of September 2026
- LessonAdding a classification: when C-46, C-7 or B pays, how the exam waiver works, what it costs, and what it does not let you doA second classification is a business decision dressed as a form. This lesson gives you both halves. The business half: what a C-46 adds for a C-10 who already installs solar under Phase 4's scope rules (almost nothing in scope, something in bidding and marketing), what a C-7 adds (a crew that can pull low-voltage without state certification cards), and what a B adds and costs (the ability to be the prime on a remodel, and the responsibility for every other trade on it). The form half: the $230 application for an additional classification on an existing license, the exam waiver under B&P 7065.3 for a qualifier with five years on a license and four years of experience in the new trade, the five-year re-exam waiver in 7065(d), what 'closely related' means in practice, and the rule that a classification you hold but do not staff is a liability, because the qualifier is responsible for all of it.Current as of September 2026
- LessonQualifiers, partners and the exit: being the RMO for another company, the 90-day clock when a qualifier leaves, and why a license cannot be soldGrowth eventually puts your name on someone else's paperwork or someone else's name on yours. This lesson covers the three situations the license law regulates tightly. Serving as the qualifier for a second company: lawful only with 20 percent common ownership, a subsidiary or joint venture, or the same majority of officers, never for more than three firms in a year, and always with real supervision and control, on pain of a misdemeanor. Losing or replacing a qualifier: a 90-day clock to notify CSLB and a 90-day clock to replace, after which the license is suspended or the classification removed, with one 90-day extension in narrow cases. And the exit: no license is transferable under any circumstances, an individual's license is canceled at death with a 90-day window for the family to request a continuance, and what a buyer actually acquires when they 'buy' an electrical contracting company.Current as of September 2026
- LessonThe office: the records the law makes you keep and for how long, the job file that wins complaints, and the four systems a two-truck shop needsSomewhere between the second truck and the fifth employee, the business stops fitting in your head and starts living in files, and the law has opinions about which files and for how long. This lesson lists them with the section beside each: every contract, document, receipt and disbursement for five years after the job (CSLB), pay stubs and payroll records for three years (Labor Code), the I-9 for three years from hire or one after separation, tax records for three to six years and employment tax records for four (IRS), IIPP training and inspection records for one year (Cal/OSHA), and the job file itself for at least the four-year complaint window and ten for structural work. It then gives the job-file structure that closed Phase 5's three-years-later complaint in an afternoon, and the four systems a small shop actually needs: a job file per job, a calendar of deadlines, a dispatch board that records hours as they happen, and a monthly close that produces the three numbers in the next lesson.Current as of September 2026
- LessonThe three numbers that predict failure: gross margin per job, days of cash, and the age of what you are owed, with the statutes that move each oneContractors rarely fail because they cannot do the work. They fail because three numbers went bad for a few months while everyone was busy: the gross margin on each job, the number of days the bank balance would carry the shop with no new money, and the age of the receivables. This lesson defines each number so a two-truck shop can compute it on the last day of the month from the job files and the bank statement, gives the healthy range and the failure signal for each, and shows how California's payment statutes move them: a deposit cap and progress payments that cannot run ahead of the work, an owner's 30-day duty to pay with a 2 percent monthly penalty, a 5 percent retention cap, the seven-day and ten-day duties to pay subcontractors, the 35-day stop-work trigger, and the rule that makes spending one job's money on another a disciplinary cause. The KPI sheet in this phase is the one page these numbers live on.Current as of September 2026
- LessonSupply-house credit, the fleet and the shelf: the personal guarantee, the supplier's preliminary notice on your customer's door, the number on the van, and use tax on what you pull from stockThree ordinary vendors shape a growing shop more than any customer does: the supply house that extends credit, the vehicles that carry the crew, and the shelf of stock in the yard. Each has a rule you should know before you sign anything. The supply-house credit application almost always contains a personal guarantee, and the supply house protects itself on every job by serving a preliminary notice on your customer within 20 days, which is lawful, ordinary, and alarming to a homeowner who has not been warned. Every commercially registered vehicle must carry your business name and license number in three-quarter-inch type, and heavier trucks bring CHP oversight. And materials pulled from stock for a job carry use tax if you did not pay tax when you bought them. This lesson is short on law and long on practice: how to read the credit terms, what to tell customers about supplier notices, how to letter the van, and how to keep the shelf from becoming an audit.Current as of September 2026
- CaseCase: the helper on a 1099Mateo Salcedo pays his helper $28 an hour on a 1099 for fourteen months, with a workers' compensation exemption on file at CSLB, because the helper 'wanted it that way' and the arithmetic looked better. Then the helper falls from a ladder on a Tuesday, the emergency room asks for the workers' compensation carrier, and every agency in this phase arrives in order: the Division of Labor Standards Enforcement with a stop order and a $1,500 penalty, the Uninsured Employers Fund paying the claim and coming back for the money, CSLB with a $10,000 minimum penalty and a suspension that dates back to the helper's first day, EDD with an audit of fourteen months of unreported wages, and the Labor Commissioner with the helper's own claim for overtime, sick leave, a late final check and a misclassification penalty. The case adds it up against what payroll would have cost, and finds the 1099 was the most expensive decision the company ever made. The names are invented; the statutes are quoted.Current as of September 2026
- CaseCase: the journeyman without a cardPriya Raman hires the best electrician she has ever worked with: twelve years in the trade, most of it in another state, references that call back, and no California certification card. She assumes experience is the credential. Eight weeks later a Labor Commissioner field team walks a tenant-improvement job, asks each person on the lift for a card or a trainee registration, and gets neither from him. The law says that moment is presumed to be her violation. The case follows the referral to CSLB, the 60-day clock it starts, what Priya does in the first week to turn a willful violation into a corrected one, how her journeyman gets lawful (registered as a trainee under her supervision while his out-of-state hours are documented for the exam), and what the file looked like when the Board closed it. The names are invented; the statute is quoted.Current as of September 2026
- TemplateTemplate: hiring checklist (the classification decision, then everything due before and after the first day)One page that starts with the only question that matters, employee or licensed subcontractor, and then walks every filing and document from the decision to the 90th day in the order it is due, with the deadline and the section beside each line. Print it the day you decide to hire; it should be finished before the start date except for the items that cannot be. Beside the blank, the checklist filled in for Mateo Salcedo's hire done right: the same helper from the case in this phase, hired as a registered trainee on payroll with coverage bound the week before.Current as of September 2026
- TemplateTemplate: new-hire packet index (every document in the personnel file, who completes it, when, and how long it is kept)The personnel file is where every deadline in this phase ends up as a piece of paper, and the file is only useful if the same sixteen documents are in the same order for every employee. This index is the cover sheet: each document, who fills it in, the deadline, where the original lives (personnel file, the separate I-9 binder, the truck binder, or the payroll service), and how long it is kept, with the section that sets the period. Beside the blank, the index for Rigo Ávila's file at Salcedo Electric on his 30th day, every line filled or marked not applicable.Current as of September 2026
- TemplateTemplate: the three-number KPI sheet (one page per month: gross margin per job, days of cash, receivables age)One page, filled in at the monthly close, that turns the office lesson's files into the three numbers the previous lesson explained: gross margin on each job closed or drawn this month against the price-book target, days of cash after subtracting the money that is not yours, and the aging of every open invoice with the statute-driven action for each band. Each line names its input so the sheet can be filled from the job files, the payroll report and the bank statement in under an hour. Beside the blank, Salcedo Electric's sheet for the month after Rigo was hired properly, showing what a loaded labor rate does to margin, what a hire does to days of cash, and how one general contractor's aging balance turned into a dated demand letter.Current as of September 2026
Phase 7
Staying Licensed
6 lessons
- LessonRenewal every two years: the expiration date, what it costs, the 90-day retroactive window, the five-year cliff, inactive status, and what an expired day does to your right to be paidThe license you worked for expires on a date CSLB set the day it issued, two years out, on the last day of a month, and nothing about the renewal is automatic. This lesson gives the mechanics as the statute writes them: when the license expires, what a timely renewal costs a C-10 in 2026 including the $20 electrician-certification surcharge, what happens on the day after expiration (you are unlicensed, with everything that means), the 90-day window in which a late renewal is made retroactive as if it never lapsed, the delinquency fee at 50 percent, the five-year cliff after which the number is gone and you start over, the option of an inactive license when you are not contracting, and the reason all of this matters more than a fee: an unlicensed day inside a job means you cannot sue to collect for it and the customer can sue to take back what they paid.Current as of September 2026
- LessonThe suspensions that need no hearing: bond, workers' compensation, qualifier, unpaid judgment, unpaid arbitration award, unpaid citation, unpaid taxes, and how each is liftedMost of what ends a license does not come from a hearing. It comes from a missed piece of paper that the statute converts into a suspension 'by operation of law,' effective before anyone at CSLB has read a file: a surety that cancels the bond, a workers' compensation policy that lapses, a qualifier who leaves and is not replaced in 90 days, a judgment nobody reported, an arbitration award or citation nobody paid, a tax bill nobody resolved. This lesson lists the seven, with the trigger, the effective date, and the specific document that lifts each, because the fix is different for each and the 90-day retroactive windows for bonds and workers' compensation are the difference between a clerical scare and a permanent unlicensed gap under 7031.Current as of September 2026
- LessonChanges you must report within 90 days: address, business name, personnel, qualifier, bond exemptions, judgments, workers' compensation, entity, and the five years after the license endsOne statute, one number: any change to what CSLB has on file must be reported in writing within 90 days, and a change reported late takes effect only when the Board receives it, with discipline available for the delay. This lesson lists what 'any change' means for a small electrical contractor (the shop moved; you added a DBA; a partner or officer came or went; the qualifier changed; the RMO's ownership dropped below 10 percent; a judgment was entered; you hired and the exemption stopped being true), what form and fee each takes, which changes cannot be reported at all because they require a new license, and the one duty that outlives the license: keep a current address on file for five years after it expires, is suspended or is canceled, because the complaint window and the disclosure periods are still running.Current as of September 2026
- LessonStaying current: the three-year code cycle, the January 1 law changes, local amendments and the new freeze on them, your crew's 32 hours, and the system that catches all of itNothing in the license law makes you take a class to renew, and everything you install is judged against a code that changes on a schedule. This lesson gives the schedule. The California Building Standards Code, including the Electrical Code, is republished every three years and takes effect on January 1 of the following year, with the 2025 edition effective January 1, 2026 and supplements in between; the Energy Code moves on the same three-year cycle. Statutes change mostly on January 1, sometimes mid-year, and several changes you already know about have future dates attached. Cities and counties may amend the state code for local conditions, and a new freeze limits residential amendments through mid-2031. Your certified electricians must renew their cards every three years with 32 hours of continuing education, and your employees get an annual rights notice every February 1. The lesson ends with the system that catches all of it in an hour a quarter, because 'I didn't know it changed' is not a defense under B&P 7110.Current as of September 2026
- CaseCase: the renewal that went to the old addressAndre Boateng moves his shop across town in the fall, letters the trucks, updates the website, and never files the one-page address change with CSLB. In February the renewal application goes to the old address. His license expires March 31. He signs a $9,600 kitchen contract on April 3, pulls the permit on the 6th, and finds out on May 14, from a homeowner's daughter who checked the license lookup before the final payment, that he has been 'expired' for six weeks. The case follows the two weeks that decide whether the gap is permanent: the day count to the 90-day retroactive window, the complete application and both fees sent by a method that proves the date, the customer who refuses to pay and cites 7031, and what the outcome would have been on day 91 instead of day 74. The names are invented; the statutes are quoted.Current as of September 2026
- TemplateTemplate: the annual compliance calendar (every fixed date the law sets, every event-driven clock, and the monthly check that catches the rest)One page for the year, in three parts. Fixed dates the law sets for everyone: January 1 statute changes, the January 15 and 31 tax deadlines, the February 1 workplace notice, the quarterly payroll returns, the estimated tax dates, the July 1 code publication in an edition year. Dates that are yours alone: the license expiration with its 60-day and 90-day markers, the bond and workers' compensation renewals, each employee's certification expiration and each trainee's annual renewal, the city business tax renewal, the policy audit. And the event-driven clocks that start when something happens: 90 days to report a change, a judgment, a departed qualifier; 90 days to make a late renewal or a replacement bond retroactive; five years to keep a job file. Beside the blank, Boateng Electric's 2027 calendar, built the month after the case in this phase.Current as of September 2026
Does this teach me how to run the business, or just pass the exam?
Both. The exam-prep modules get you the license. The After the License track covers what happens next, in phases, and every phase listed on this page is live now: what CSLB needs before the number issues, the two bonds, the workers compensation rule as the statute actually reads today, what the qualifier is legally responsible for, why renting a license is a crime, the entity decision and its California tax numbers, the EIN and the books, city business tax, the insurance stack a general contractor will demand, sales tax on materials versus fixtures, quarterly estimates, where the first ten jobs come from, the license number on every ad and the van, a flat-rate price book, estimating as a six-step method, and public works with DIR registration and prevailing wage, then contracts and getting paid: the home improvement contract with every B&P 7159 notice in the words of the statute, the $1,000 or 10% deposit cap, the $750 service and repair contract, subcontracts with general contractors, change orders, mechanics liens and the 20-day preliminary notice, the four lien release forms, stop payment notices, small claims and collections, and how to take payment, with three worked cases; then the field: one diagnostic method applied to every call, permits and inspections with the four exemptions the code names, the daily-use code with the actual numbers (box fill, ampacity, AFCI and GFCI locations, working clearance, grounding), load calculations three ways including the 7,200 volt-ampere EV floor, service upgrades and utility coordination, EV chargers and load management, solar and storage with Rule 21 and Net Billing, troubleshooting trees, aluminum wiring and knob-and-tube, the Title 24 lighting rules, generators and interlocks, C-10 versus C-7 scope, Cal/OSHA electrical safety and the IIPP and heat plan every employer owes, NM versus MC versus EMT, three-phase and motor circuits, and the EPA lead rule and asbestos survey, with seven worked cases; then customers, warranties and complaints: presenting options and price without apologizing, delivering bad news with the change order that goes with it, the four-year and ten-year windows at CSLB and in court, a warranty policy you can honor without losing money, the CSLB complaint process step by step with what becomes public and for how long, reviews and the two laws that govern them, and walking away from the wrong customer without abandoning the job, with two worked cases; then growing: why almost everyone you pay to pull wire is an employee and the one way a subcontractor is not, the state electrician certification your crew must carry and the $25 trainee route that makes a new hire lawful in a week, the payroll rules with the 2026 numbers (minimum wage, overtime, meals and rest, paydays, pay stubs, sick leave, final pay), the thirty-day sequence from workers compensation coverage to the new-hire report, adding a C-46, C-7 or B and the exam waiver, being a qualifier for someone else and what happens when a qualifier leaves, the records the law makes you keep and for how long, the three numbers that predict failure, and supply-house credit, the fleet and use tax on stock, with two worked cases; and finally staying licensed: the renewal every two years with its fees, the 90-day retroactive window and the five-year cliff, inactive status, the seven suspensions that take effect without a hearing and the document that lifts each, the changes you must report within 90 days and the five years the address of record outlives the license, the three-year code cycle and the January 1 law changes, with a worked case, plus printable templates for the setup checklist, insurance matrix, estimate worksheet, price book, 90-day marketing plan, home improvement contract, service and repair contract, change order, preliminary notice, the four lien releases, demand letters, subcontract review checklist, job-site checklist, pre-inspection checklist, load calculation worksheet, IIPP starter, heat illness prevention plan, customer options sheet, workmanship warranty statement, a written response to a CSLB complaint, hiring checklist, new-hire packet index, the three-number KPI sheet and the annual compliance calendar. All eight phases are live. When the law changes, the lesson changes, at no extra charge. Every lesson cites its .gov source and shows the month it was last checked.
