The CSLB complaint process from the contractor's side: the letter, mediation, investigation, arbitration, citations, and what becomes public
In one paragraph
One 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.
The rule
The registrar investigates every verified complaint and may cite, suspend or revoke (B&P 7090). Complaints meeting the criteria of 7085 are referred to arbitration, mandatory where the contract price or damages are at or below the bond amount and voluntary up to $50,000, and failure to comply with an award suspends the license by operation of law 30 days after notice (7085.6). A citation states the sections violated and may order correction, payment to the injured party and a civil penalty of $500 to $8,000, or $1,500 to $30,000 for permit, workers' compensation and unlicensed-subcontractor violations (7099, 7099.2). Complaints resolved in the contractor's favor are not disclosed; citations are public for five years after compliance and accusations resulting in discipline for seven (7124.6).
Why it matters
Most contractors meet the complaint process for the first time in a panic, respond by phone, argue with the investigator and make a small dispute into a citation. The process rewards the contractor who answers in writing, with the file, on time, and who understands that the first letter is an invitation to fix it. Knowing the steps, the numbers and the disclosure rules is the difference between a closed complaint nobody sees and a citation that sits on your license for five years.
