California Contractor License Requirements
One of the most structured systems in the country — 40+ specialty classifications under a single statewide board.
License Requirement
Licensing body: California Contractors State License Board (CSLB) — cslb.ca.gov
California requires a statewide contractor license through CSLB for most construction work. Classifications include A (General Engineering), B (General Building), B-2 (Residential Remodeling), and 40+ specialty C-classes (e.g., C-10 Electrical, C-36 Plumbing, C-39 Roofing, C-46 Solar).
Exam
Two-part exam administered by PSI Services under contract to CSLB: a Law & Business exam (115 questions, 210 minutes) and a Trade exam (115 questions, 210 minutes), each requiring a 72% passing score.
Bonding
A $25,000 contractor license bond is required for licensure. Whether CSLB separately mandates general liability insurance as a blanket condition was not independently reconfirmed during this research pass — CSLB is commonly understood to require workers' compensation coverage only once a licensee has employees. Confirm current insurance requirements directly with CSLB.
Continuing Education
Not confirmed during this research pass. CSLB is commonly described as not requiring continuing education for standard renewal, but this was not independently reverified — check cslb.ca.gov before relying on it.
Experience Requirements
4 years of journey-level experience within the prior 10 years, consistently confirmed across sources.
Reciprocity
Reciprocity is believed to be very limited to none; this was not independently reverified this pass — confirm directly with CSLB.
Licensing requirements change and vary by locality within a state. Always verify current requirements with your state's contractor licensing board before applying.

Research note: Exam structure, bond amount, classifications, and the 4-year experience rule are well-supported. CE, renewal cycle, blanket insurance requirement, and reciprocity need direct confirmation at cslb.ca.gov before you rely on them.
