Plumber License from Maine to California: Does It Transfer? (2026)
Does California accept a Maine plumbing license?
There is no California state license to transfer into: California issues no statewide journeyman plumber license. Any licensing for this work is handled below the state level (a city, county or contractor-level authority), so check with the authority where you will work.

Verdict
No state license to transfer
There is nothing at the state level to transfer your Maine license into: California issues no statewide plumbing license, so plumbers there are licensed at the contractor level or by cities and counties. Not applicable at the journeyman level — California issues no state journeyman plumber license, so there is no state journeyman trade exam. Plumbing is licensed only at the contractor level by the Contractors State License Board (C-36 Plumbing). At that contractor tier, CSLB has a reciprocity agreement covering the C-36 classification with Arizona only: an Arizona C-37 or C-37R contractor who has held that license active and in good standing for the previous five years may have the C-36 trade exam waived (CSLB reserves the right to require it), but must still pass CSLB's Law and Business exam. CSLB's other reciprocity partners (Nevada, Louisiana, Mississippi, North Carolina) do not map to C-36 Plumbing. The move is a local or contractor-board application, not a reciprocity filing — identify the authority that governs your worksite and work from its exam, experience, and fee rules. Your Maine license may count toward a local experience requirement, but California has no state credential for it to reciprocate into.
What's different between Maine and California
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into California. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
Maine to California (this page): No state license to transfer.
California to Maine (the reverse move): No state license to transfer.
California issues no statewide journeyman plumber license, so neither direction is a state-license transfer.
- Does coming from Maine matter?
Coming from Maine does not change the answer: every origin (the other 49 states and DC) gets the same result for a move into California.
- Fee and processing
California issues no statewide journeyman plumber license, so there is no California state license application fee or processing time to compare with Maine's.
- Exam rules on record
California and Maine carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- California (this move): Not applicable at the journeyman level — California issues no state journeyman plumber license, so there is no state journeyman trade exam. Plumbing is licensed only at the contractor level by the Contractors State License Board (C-36 Plumbing). At that contractor tier, CSLB has a reciprocity agreement covering the C-36 classification with Arizona only: an Arizona C-37 or C-37R contractor who has held that license active and in good standing for the previous five years may have the C-36 trade exam waived (CSLB reserves the right to require it), but must still pass CSLB's Law and Business exam. CSLB's other reciprocity partners (Nevada, Louisiana, Mississippi, North Carolina) do not map to C-36 Plumbing.
- Maine (the reverse move): Maine may issue a journeyman plumber license without its exam to an applicant licensed in another state whose licensing standards and experience requirements are at least equivalent to Maine's and that grants Maine plumbers the same privilege (Title 32 sec. 3504-A); no partner states are named, and an applicant who does not meet that equivalency/reciprocal test must pass the Maine journeyman exam
What changes, Maine → California
| Maine (current) | California (destination) | |
|---|---|---|
| Application fee | $200 ($200 journeyman plumber license fee (biennial renewal also $200); +$21 criminal background check fee (surcharge, not in the range). A separate examination fee applies on the exam track but was not listed on the official fee schedule.) | No state journeyman plumber license exists, so there is no journeyman fee. For reference, the CSLB C-36 plumbing CONTRACTOR license (contractor tier, out of scope) is $450 original application + $200 initial license fee (sole owner) / $350 (non-sole owner), plus a bond and Live Scan fingerprint fee |
| Processing time | No board-stated processing time; since 2024 all applications, exams, and renewals are filed through Maine's online licensing system | Not applicable — no state journeyman plumber license is issued |
| Licensing authority | Maine Plumbers' Examining Board (Office of Professional and Occupational Regulation) | California Contractors State License Board (CSLB) |
The destination column is what you must satisfy — California sets the rules for this move.
