Plumber License from Arizona to Ohio: Does It Transfer? (2026)
Does Ohio accept an Arizona plumbing license?
There is no Arizona state license to carry to Ohio: Arizona issues no statewide journeyman plumber license. Ohio does license this work, so ask the Ohio Construction Industry Licensing Board (OCILB) — Ohio Department of Commerce, Division of Industrial Compliance 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 Ohio to verify or endorse. Ohio does license plumbers, through the Ohio Construction Industry Licensing Board (OCILB) — Ohio Department of Commerce, Division of Industrial Compliance, 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. Ohio waives its OCILB plumbing trade exam only for applicants who currently hold a South Carolina or West Virginia plumbing license obtained by examination (not by grandfathering or reciprocity); an out-of-state licensee who instead got their license by grandfathering or reciprocity must take both the Ohio plumbing exam and the Ohio Business and Law exam, and every other applicant must qualify with five years of trade experience and pass the Ohio plumbing exam.
What's different between Arizona and Ohio
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Ohio. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
Arizona to Ohio (this page): No state license to transfer.
Ohio 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 Ohio.
The others get: licensure by endorsement (39) and reciprocity agreement (2).
- Reciprocity agreements
Ohio's reciprocity agreement list names 2 states (South Carolina and West Virginia), not including Arizona.
- 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 Ohio's.
- Exam rules on record
Ohio and Arizona carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Ohio (this move): Ohio waives its OCILB plumbing trade exam only for applicants who currently hold a South Carolina or West Virginia plumbing license obtained by examination (not by grandfathering or reciprocity); an out-of-state licensee who instead got their license by grandfathering or reciprocity must take both the Ohio plumbing exam and the Ohio Business and Law exam, and every other applicant must qualify with five years of trade experience and pass the Ohio plumbing exam
- 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 → Ohio
| Arizona (current) | Ohio (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) | $25 ($25.00 non-refundable reciprocity application fee per trade; proof of at least $500,000 contractor liability insurance required. Non-reciprocal applicants pay a $25 exam application fee plus BCI and FBI background-check costs.) |
| Processing time | Not applicable — no state journeyman plumber license is issued | No board-stated processing time; reciprocity applications are approved or denied by board review |
| Licensing authority | Arizona Registrar of Contractors (ROC) | Ohio Construction Industry Licensing Board (OCILB) — Ohio Department of Commerce, Division of Industrial Compliance |
The destination column is what you must satisfy — Ohio sets the rules for this move.

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