California does not issue a separate state “journeyman plumber” license the way some states do. Instead, to run plumbing work and pull permits you get a plumbing license in California as a licensed C-36 Plumbing Contractor through the state contractor board below.
Who runs plumbing licensing in California
The Contractors State License Board (CSLB) issues the C-36 Plumbing Contractor classification. That is the license you need to contract plumbing work over $500 in labor and materials.
C-36 requirements
- Experience: At least four years of journey-level plumbing experience within the past 10 years. The CSLB accepts W-2 employment under a licensed contractor, self-employment, and qualifying union or apprenticeship training.
- Two exams: A Law & Business exam and the C-36 trade exam. Both are closed-book, multiple choice, up to 115 questions each.
- Contractor bond: After you pass, you have 90 days to file a contractor license bond (currently a $25,000 minimum) before the license activates.
- Fees: An initial licensing fee applies (around $200 for a sole owner). Confirm current amounts on the CSLB site.
The basic path
Get your four years of documented journey-level experience, apply to the CSLB, pass both exams, file your bond, and activate the license. If you work as an employee plumber under a licensed contractor, you are covered by their license until you get your own C-36.
Reciprocity
California has limited reciprocity with a few states for the trade portion of the exam. Check the CSLB reciprocity page for the current list before assuming an out-of-state license helps.
How to apply or check a license
Apply, renew, and verify any contractor through the CSLB. Their license lookup shows bond and status for any C-36 holder.
