Plumber License from Arizona to New Hampshire: Does It Transfer? (2026)
Does New Hampshire accept an Arizona plumbing license?
There is no Arizona state license to carry to New Hampshire: Arizona issues no statewide journeyman plumber license. New Hampshire does license this work, so ask the New Hampshire Office of Professional Licensure and Certification (OPLC) — Mechanical Safety and Licensing Board 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: Arizona issues no statewide journeyman plumber license — plumbing there is regulated at the contractor level or by cities and counties — so there is no Arizona state license for New Hampshire to verify or endorse. New Hampshire does license plumbers, through the New Hampshire Office of Professional Licensure and Certification (OPLC) — Mechanical Safety and Licensing Board, 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 Arizona license, a contractor-level credential or your documented hours; otherwise plan to qualify as a new journeyman applicant. New Hampshire licenses a journeyman plumber by endorsement — without requiring its own plumbing examination — when the applicant holds an active, good-standing journeyman plumber license from one of 33 'qualifying jurisdictions' whose requirements OPLC deems substantially similar (RSA 310:17 / HB 594, rule Plc 313.34); applicants from any other state must qualify through New Hampshire's apprenticeship route and pass the New Hampshire plumbing examination.
What's different between Arizona and New Hampshire
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into New Hampshire. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
Arizona to New Hampshire (this page): No state license to transfer.
New Hampshire to Arizona (the reverse move): No state license to transfer.
Arizona issues no statewide journeyman plumber license, so neither direction is a state-license transfer.
- Does coming from Arizona matter?
Coming from Arizona matters here: only 9 of 50 origins (the other 49 states and DC) get this result for a move into New Hampshire.
The others get: licensure by endorsement (41).
- Fee and processing
Arizona issues no statewide journeyman plumber license, so there is no Arizona state license application fee or processing time to compare with New Hampshire's.
- Exam rules on record
New Hampshire and Arizona carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- New Hampshire (this move): New Hampshire licenses a journeyman plumber by endorsement — without requiring its own plumbing examination — when the applicant holds an active, good-standing journeyman plumber license from one of 33 'qualifying jurisdictions' whose requirements OPLC deems substantially similar (RSA 310:17 / HB 594, rule Plc 313.34); applicants from any other state must qualify through New Hampshire's apprenticeship route and pass the New Hampshire plumbing examination
- Arizona (the reverse move): Not applicable at the journeyman level — Arizona issues no state journeyman (or master) plumber license, so there is no state journeyman trade exam to waive or require. Plumbing is regulated only at the contractor level by the Arizona Registrar of Contractors (e.g., C-37 commercial plumbing, plus residential and dual plumbing classifications); individual journeymen and apprentices are not state-licensed and work under a licensed contractor. At the contractor level, A.R.S. § 32-1122 lets the Registrar waive the trade exam for a qualifying party who held an Arizona license in the same classification within five years, and Form RC-L-200G extends a comparable out-of-state trade-exam waiver, but the Arizona Statutes and Rules Exam (SRE) is never waived.
What changes, Arizona → New Hampshire
| Arizona (current) | New Hampshire (destination) | |
|---|---|---|
| Application fee | No state journeyman plumber license exists, so there is no journeyman application/license fee. For reference, ROC contractor plumbing fees under Ariz. Admin. Code R4-9-130 are $100 application + $480 biennial for C-37 commercial and $80 application + $270 biennial for the residential plumbing classification (contractor tier, out of scope for the journeyman credential) | $190–$210 (Journeyman Plumber application fee $190 plus $20 certificate fee; the fingerprint / criminal background check fee is additional and paid separately. (Master Plumber application fee is $310)) |
| Processing time | Not applicable — no state journeyman plumber license is issued | No board-stated processing time; under Plc 313.07(c) OPLC may issue an 'Active-Provisional' license once the application, fee, and fingerprints are submitted and the applicant qualifies by endorsement, pending background-check results |
| Licensing authority | Arizona Registrar of Contractors (ROC) | New Hampshire Office of Professional Licensure and Certification (OPLC) — Mechanical Safety and Licensing Board |
The destination column is what you must satisfy — New Hampshire sets the rules for this move.

What happens to my Arizona credential after I'm licensed in New Hampshire?
