Only a registered home improvement salesperson (HIS) may solicit, sell, negotiate or execute home improvement contracts for a licensed contractor away from the contractor's normal place of business. Ask to see the HIS registration pocket card, and check the HIS or contractor license at cslb.ca.gov or by calling 800-321-2752. (source: Contractors State License Board)

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 of the act, which is the four years on CSLB's complaint page. A complaint about latent structural defects, meaning defects not apparent by reasonable inspection, may be filed within 10 years. If your problem is older than four years, call CSLB at 800-321-2752 and ask whether it qualifies. (source: Contractors State License Board) (source: California Legislature)
