“The most important document in any construction project isn't the permit — it's the contract. A vague contract with a scope defined as 'as per plans' is not sufficient protection for a homeowner. The contract should specify: payment schedule tied to milestones, allowances for specified items, exclusions list, change order threshold, and dispute resolution process.”

Pro Tip

Always ask for a contractor's license verification at CSLB.ca.gov before signing any contract. A B-General Building Contractor license covers structural work; specialty work (electrical, plumbing, HVAC, roofing) requires separate C-license contractors on the team. Verify that any subcontractors on your project also have current CSLB licenses.

Frequently Asked Questions

+How do I check if a contractor is licensed in California?

Visit cslb.ca.gov and click 'Check a License.' Enter the license number or contractor name. The results show: license status, classification, bond status, workers comp status, and any complaints. You can also call CSLB at 1-800-321-CSLB (2752). Always verify before signing any contract.

+What happens if I hire an unlicensed contractor in California?

Hiring an unlicensed contractor means: no CSLB bond protection, no recourse through CSLB complaint process, no workers comp coverage (you become liable for injuries), the contract is unenforceable in court, and any permits pulled are invalid. The contractor faces fines up to $15,000 and potential jail time.

+What is the minimum bond for a CA contractor?

California requires a $25,000 contractor's license bond (increased from $15,000 in 2023). This bond protects consumers if the contractor fails to complete work or violates the law. The bond amount is the maximum CSLB can recover per claim, not per project.
