Plumber License from California to Maine: Does It Transfer? (2026)
Does Maine accept a California plumbing license?
There is no California state license to carry to Maine: California issues no statewide journeyman plumber license. Maine does license this work, so ask the Maine Plumbers' Examining Board (Office of Professional and Occupational Regulation) whether it credits a local license or your documented experience; otherwise you qualify as a new applicant.

Verdict
No state license to transfer
The issue on this move is the starting point: California issues no statewide journeyman plumber license — plumbing there is regulated at the contractor level or by cities and counties — so there is no California state license for Maine to verify or endorse. Maine does license plumbers, through the Maine Plumbers' Examining Board (Office of Professional and Occupational Regulation), and it reviews out-of-state plumbers for endorsement, but that route starts from a state license. Ask the board, in writing, whether it credits a local California license, a contractor-level credential or your documented hours; otherwise plan to qualify as a new journeyman applicant. 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's different between California and Maine
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Maine. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
California to Maine (this page): No state license to transfer.
Maine to California (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 California matter?
Coming from California matters here: only 9 of 50 origins (the other 49 states and DC) get this result for a move into Maine.
The others get: licensure by endorsement (41).
- 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
Maine and California carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Maine (this 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
- California (the reverse 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.
What changes, California → Maine
| California (current) | Maine (destination) | |
|---|---|---|
| Application fee | 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 | $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.) |
| Processing time | Not applicable — no state journeyman plumber license is issued | No board-stated processing time; since 2024 all applications, exams, and renewals are filed through Maine's online licensing system |
| Licensing authority | California Contractors State License Board (CSLB) | Maine Plumbers' Examining Board (Office of Professional and Occupational Regulation) |
The destination column is what you must satisfy — Maine sets the rules for this move.

- Review Maine's requirements on the Maine Plumbers' Examining Board (Office of Professional and Occupational Regulation) website (linked below) — rules change.
- Ask the Maine Plumbers' Examining Board (Office of Professional and Occupational Regulation) whether it credits a local California license or your documented experience: California issues no statewide journeyman plumber license, so there is no state license to verify.
- Otherwise apply as a new applicant: meet Maine's education/experience requirements and pass the exams it requires.
- Submit the application with fees listed above, and allow for the processing time shown there.

Frequently asked questions
What happens to my California credential after I'm licensed in Maine?
Nothing changes it. California issues no statewide journeyman plumber license, so any local or contractor-level California credential you hold runs on its own authority's renewal rules, independently of your Maine license.
