CSLB (Contractors State License Board)

The California agency that licenses, regulates, and disciplines contractors.

The Contractors State License Board issues, suspends, and revokes contractor licenses across California. Any project over $500 (labor + materials) must be performed by a CSLB-licensed contractor. Licenses are classified by trade — Class B (General Building), C-10 (Electrical), C-36 (Plumbing), C-20 (HVAC), and so on.

Verify license status before signing any contract at cslb.ca.gov/OnlineServices/CheckLicenseII. California caps contractor deposits at $1,000 or 10% of the contract, whichever is less — anything more is a license violation.
