Plumbing

Renewal: Biennial

License types: C-36 Plumbing
Experience: 4 years journeyman-level within past 10 years

Website: www.cslb.ca.gov
Notes: CSLB uses a single licensing framework across all 44 specialty classifications. Same application process for plumbing as HVAC.

Electrical

Renewal: Biennial
CE hours: No CSLB CE requirement; electrician certification requires 32 hours CE per 3-year cycle
Initial cost: $699
License types: C-10 Electrical
Experience: 4 years journeyman-level within past 10 years
Exam: Trade exam + Law & Business exam
Bond: $25,000 contractor bond
Insurance: Workers' comp with employees
Reciprocity: None
Board: Contractors State License Board (CSLB) + Division of Apprenticeship Standards
Website: www.cslb.ca.gov
Notes: California has both a CSLB contractor license (C-10) and a separate electrician certification program through the Division of Apprenticeship Standards. The C-10 is for the contracting business; individual electricians may also need certification.

California's Contractors State License Board (CSLB) manages all trade contractor licenses under a unified system with 44 specialty classifications. HVAC is C-20, plumbing is C-36, and electrical is C-10. The application process is identical across classifications — 4 years of experience, two exams (trade + law & business), and the same fee structure.

California is one of the more expensive states to get licensed. The initial cost is approximately $699 in state fees, plus a mandatory $25,000 contractor bond (increased from $15,000 under AB 2622, effective January 2025). The bond alone can cost $100–$500/year in premiums depending on your credit. Workers' comp insurance is mandatory if you have any employees.

Important 2025 change: AB 2622 raised the licensing threshold from $500 to $1,000. Projects where the total cost (labor + materials) is under $1,000 no longer require a contractor license. This affects handyman-type work but not typical HVAC, plumbing, or electrical jobs.

California has zero reciprocity agreements. No matter where you're currently licensed, you must pass both California exams to work in the state. This makes California one of the hardest states to enter from out of state.
