How to check a plumber's license in Thousand Oaks

  1. Look the company up by name or license number (search Thousand Oaks). 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. Get the bid and contract in writing with the license number on it. If the job tops $1,000 in labor and materials, a licensed plumber is required by law. See the $1,000 rule.
