California contractor licensing is overseen by the CSLB. As of July 28, 2026, the licensure threshold is $1,000, active licenses renew every two years, and current CSLB fees are $450 for the original application plus a $200 (sole owner) or $350 (non‑sole owner) initial license fee, with renewals at $450/$700. Workers’ compensation rules are expanding in phases and universal coverage is delayed to January 1, 2028; LLCs must maintain general liability insurance, and all licensees must maintain the $25,000 contractor bond.

Do You Need a License to Run a Trades and General Contractors Business in California?
Yes. In California, contractors are licensed by the Contractors State License Board (CSLB).

How to Apply: Step-by-Step Application Process for a California General Contractor License
Apply through the CSLB. The qualifying individual must meet experience and exam requirements before the license can be issued.
- Form your business if applicable and, for corporations/LLCs/LPs, register with the California Secretary of State. Sole proprietors do not register with SOS just to obtain a CSLB license (CSLB – Applicants).
- Submit the Application for Original Contractor License to CSLB (application).
- Document at least four years of journey‑level/foreman/supervisor/contractor experience in the classification within the last 10 years (education/approved training may count for up to three years) (CSLB – Experience).
- Pass the Law & Business exam and your trade exam (most classifications) (CSLB – Exam overview; study guides).
- After passing, submit issuance items: contractor bond(s), fingerprints, initial license fee, and required insurance (e.g., workers’ compensation; LLC liability insurance if applicable) (CSLB – FAQ; CSLB – Issuing My License).
How Much Does It Cost & How Long Does It Take to Get a California General Contractor License?
Current CSLB fees (selected):

See CSLB’s full fee schedule for details and other fees (CSLB – List of All Fees).

What is the current dollar threshold that triggers the need for a CSLB license?
$1,000 total project value (labor and materials), or when a building permit is required or additional workers are used (CSLB – Step 1: Before Applying).
