How to check a general engineering contractor's license in San Francisco

  1. Open the general engineering contractor's profile from the table below (or search San Francisco listings by name). Check that A appears among its classifications and that the primary status reads Clear. What A covers.
  2. Confirm it live with CSLB's Instant License Check. Statuses change between our weekly refreshes, especially workers' comp and bond suspensions.
  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).
