General contractors hold CSLB's B (General Building Contractor) license, which covers projects that combine two or more unrelated trades. See the B General Building Contractor guide for what the license covers.

How to check a general contractor's license in Walnut

  1. Look the company up by name or license number (search Walnut). On the profile, confirm three things: Clear status, the B license for this kind of work, and a contractor's bond on file.
  2. Before any money changes hands, verify the license on CSLB's own lookup. Our data comes from CSLB's weekly file, so a very recent change may not show here yet.
  3. Ask for the pocket license and a photo ID and match the name to your contract. Work of $1,000 or more needs a license (the $1,000 rule), and a down payment can't exceed $1,000 or 10% (down payment rules).
