54.8% report a workers' comp exemption, 3.6 points higher than the statewide figure for plumbers (51.2%), so many of these businesses say they have no employees. The share with a suspension (2.4%) is close to the Contra Costa County rate for the same license (3.1%).

5 of these licenses are less than a year old, while 42.9% have been held for 10 years or more. The median is 8.5 years.

In California this work generally calls for the C-36 Plumbing Contractor license (or a B license when it is part of a larger multi-trade job). See the C-36 Plumbing Contractor guide for what the license covers.

How to check a plumber's license in Richmond

  1. Open the plumber's profile from the table below (or search Richmond listings by name). Check that C-36 appears among its classifications and that the primary status reads Clear. What C-36 covers.
  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).
