55.9% report a workers' comp exemption, 4.7 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 (3.9%) is close to the Alameda County rate for the same license (3.4%).

4 of these licenses are less than a year old, while 59.1% have been held for 10 years or more. The median is 15.1 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 Oakland

  1. Look the company up by name or license number (search Oakland). 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. 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. Match the license holder's name to the name on the written contract and the person you meet. Since 55.9% of Oakland plumbers claim a workers' comp exemption, ask who will actually do the work. Hiring checklist.
