CSLB handles violations of contractor license law, licensed or unlicensed, for up to four years from the date of the act. A CSLB investigation does not guarantee restitution; to recover money you may need to go to court. CSLB also takes Building Permit Violation Referrals for contractors who fail to pull a permit.

Complaint deadlines depend on the kind of problem (B&P 7091). A complaint about a problem you could see on reasonable inspection must be filed within four years. A complaint about latent structural defects, meaning defects not apparent by reasonable inspection, may be filed within 10 years.
