Frequently asked questions
How do I verify a California contractor's license?
Find the contractor by trade and city in this directory, or look up their license number on the CSLB "Check a License" tool. Confirm the status reads active and the classification matches your project.
Is the license data official?
Yes. Every profile is sourced from the California Contractors State License Board (CSLB) public record and shows the date it was last verified.
