Plumber License from Missouri to Michigan: Does It Transfer? (2026)
Does Michigan accept a Missouri plumbing license?
There is no Missouri state license to carry to Michigan: Missouri issues no statewide journeyman plumber license. Michigan does license this work, so ask the Michigan Department of Licensing and Regulatory Affairs — Bureau of Construction Codes (BCC), Plumbing 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 Michigan to verify or endorse. Michigan does license plumbers, through the Michigan Department of Licensing and Regulatory Affairs — Bureau of Construction Codes (BCC), Plumbing, 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. Michigan does not reciprocate with any state and waives its journey plumber exam for no one: every applicant, in-state or out, must pass Michigan's written AND practical (hands-on) journey plumber examinations. An out-of-state plumber may receive credit for out-of-state experience — documented on the BCC Out-of-State License Verification form — toward the 6,000-hour eligibility requirement to be approved to sit for the exam, but the examination is mandatory.
What's different between Missouri and Michigan
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Michigan. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
Missouri to Michigan (this page): No state license to transfer.
Michigan 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 Michigan.
The others get: licensure by endorsement (41).
- 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 Michigan's.
- Exam rules on record
Michigan and Missouri carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Michigan (this move): Michigan does not reciprocate with any state and waives its journey plumber exam for no one: every applicant, in-state or out, must pass Michigan's written AND practical (hands-on) journey plumber examinations. An out-of-state plumber may receive credit for out-of-state experience — documented on the BCC Out-of-State License Verification form — toward the 6,000-hour eligibility requirement to be approved to sit for the exam, but the examination is mandatory.
- 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 → Michigan
| Missouri (current) | Michigan (destination) | |
|---|---|---|
| Application fee | No state fee — plumber licensing fees are set by each local jurisdiction and vary; consult the specific city or county board | $40–$90 ($40 journey plumber license/application fee plus $50 examination fee (MCL 339.6121, Skilled Trades Regulation Act, 2016 PA 407). The same fees apply to out-of-state applicants; the exam is administered by PSI.) |
| 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; the application, out-of-state verification, and license fee are mailed to LARA BCC and the exam is scheduled through PSI |
| 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) | Michigan Department of Licensing and Regulatory Affairs — Bureau of Construction Codes (BCC), Plumbing |
The destination column is what you must satisfy — Michigan sets the rules for this move.

- Submit the application with fees listed above, and allow for the processing time shown there.

What happens to my Missouri credential after I'm licensed in Michigan?
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 Michigan license.
