Plumber License from Missouri to Ohio: Does It Transfer? (2026)
Does Ohio accept a Missouri plumbing license?
There is no Missouri state license to carry to Ohio: Missouri 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: Missouri issues no statewide journeyman plumber license — plumbing there is regulated at the contractor level or by cities and counties — so there is no Missouri 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 Missouri 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 Missouri 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
Missouri to Ohio (this page): No state license to transfer.
Ohio to Missouri (the reverse move): No state license to transfer.
Missouri issues no statewide journeyman plumber license, so neither direction is a state-license transfer.
- Does coming from Missouri matter?
Coming from Missouri 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 Missouri.
- Fee and processing
Missouri issues no statewide journeyman plumber license, so there is no Missouri state license application fee or processing time to compare with Ohio's.
- Exam rules on record
Ohio and Missouri 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
- Missouri (the reverse move): Not applicable — Missouri issues no state-level plumber license; each city or county board of examiners sets its own examination, so there is no statewide credential to transfer and no state exam to waive
What changes, Missouri → Ohio
| Missouri (current) | Ohio (destination) | |
|---|---|---|
| Application fee | No state fee — plumber licensing fees are set by each local jurisdiction and vary; consult the specific city or county board | $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 | No statewide process; timelines are set by each local board (e.g., the St. Louis Board of Examiners reviews applications at its monthly board meetings) | No board-stated processing time; reciprocity applications are approved or denied by board review |
| Licensing authority | No state plumbing board — the Missouri Division of Professional Registration does not license plumbers; licensing is local (e.g., St. Louis Board of Examiners of Plumbers and Drainlayers) | 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.

- Ask the Ohio Construction Industry Licensing Board (OCILB) — Ohio Department of Commerce, Division of Industrial Compliance whether it credits a local Missouri license or your documented experience: Missouri issues no statewide journeyman plumber license, so there is no state license to verify.
- Otherwise apply as a new applicant: meet Ohio'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 Missouri credential after I'm licensed in Ohio?
Nothing changes it. Missouri issues no statewide journeyman plumber license, so any local or contractor-level Missouri credential you hold runs on its own authority's renewal rules, independently of your Ohio license.
