Common questions
Is this the official CSLB license lookup?
No. We search the Contractors State License Board's public data download for San Diego County B (General Building) licenses, refreshed monthly. For the official, real-time status use the CSLB Instant License Check.
Why can't I find my contractor?
We cover active B (General Building) licenses with a San Diego County address. Your contractor may be licensed in another county, under a different classification or legal name, or their license may be inactive. Check the official CSLB lookup before you sign.
What should a good license record show?
An active status with no disciplinary actions, a B classification for new construction such as an ADU, a contractor's bond on file, and workers' comp insurance or a valid exemption, which is allowed only for contractors with no employees.
