Before you hire in Alameda County
- A license is suspended automatically when the contractor's bond or required workers' compensation lapses, so check both, not just the license.
- Our California data covers licenses that can be renewed; revoked or cancelled licenses are not in the board's bulk file. If a contractor isn't found here, check the CSLB directly.
Questions about California licensing are answered on the California contractor license lookup page. Confirm any license on the Contractors State License Board license search before you sign.

Other California counties
County is assigned from each license's business ZIP code using the U.S. Census Bureau's 2020 ZIP-to-county relationship file. A ZIP that crosses a county line is counted in the county holding most of its area, and licenses with an out-of-state address are not in any county.
