This includes sole proprietors, partnerships, corporations, and LLCs performing construction, remodeling, demolition, or repair work.
Working without a CSLB license in California is a misdemeanor. Unlicensed contractors cannot file a mechanic’s lien and are subject to fines up to $15,000 per violation. Homeowners who hire unlicensed contractors may also face liability issues.

CSLB License Requirements Checklist
✓ 4 Years Trade Experience
You must have at least 4 years of journeyman-level experience in your trade within the last 10 years. Experience must be documented with employer verifications or client affidavits.
✓ Pass Trade & Law Exam
Two-part exam: Trade section (specific to your license classification) and Law & Business section (covers contracts, labor law, workers comp, OSHA). Must pass both with 72%+ score.
✓ Contractor’s Bond — $25,000
All CSLB licensees must maintain a $25,000 contractor’s bond filed with the CSLB. Bond cost is typically $150–$400/year from a surety company.
✓ Workers Compensation (if you have employees)
If you have any employees (including part-time), California requires workers’ compensation insurance. You must file a certificate with the CSLB. Sole proprietors with no employees can file a workers’ comp exemption.
How Bookkeeping Champs Supports Your CSLB Compliance
Bookkeeping Champs helps CSLB contractors in Los Angeles and Ventura County stay in compliance by managing the financial side of their license requirements — tracking bond renewal dates, workers’ comp audit preparation, payroll records for license renewals, and the clean financial records CSLB requires for license applications and renewals.
How often do I renew my CSLB license?
CSLB licenses renew every two years. You’ll receive a renewal notice 60–90 days before expiration. Renewal requires paying the renewal fee ($450 for active status) and continuing education for most classifications. Always renew on time — a lapsed license means you cannot legally work until reinstated.
What happens if my CSLB license lapses?
A lapsed CSLB license means you cannot legally contract for work over $500 in California. If you work while lapsed you face fines up to $15,000 per job. Reinstatement requires paying back fees plus penalties. Keep your bond, workers’ comp, and renewal fees current — Bookkeeping Champs tracks all these deadlines for our clients.
