California Contractor License Lookup
Checked 2026-11-13.
California licenses contractors through the Contractors State License Board. The board's Check a License page searches by license number, business name, or personnel name. A number printed on a bid is not the record. Open the board's result and read whether the license is active and whether the classification covers the work.
Cities and counties still issue permits. The license check does not replace the permit. The board's consumer pages, linked from our license guide, describe insurance and the license bond in the board's own words.
Verify this with the board or the city before you hire. Rules change, and a city or county can require its own license on top of a state record. This is general information, not legal advice.
