How to check a plumber's license in San Ramon

  1. Look the company up by name or license number (search San Ramon). On the profile, confirm three things: Clear status, the C-36 license for this kind of work, and a contractor's bond on file.
  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).
