Plumber License from Indiana to Michigan: Does It Transfer? (2026)
Does Michigan accept an Indiana plumbing license?
A plumbing license transfers from Indiana to Michigan by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Michigan Department of Licensing and Regulatory Affairs — Bureau of Construction Codes (BCC), Plumbing, verify your Indiana license, and meet Michigan's endorsement requirements. 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.

Verdict
Licensure by endorsement
Indiana is not among the states Michigan names for an exam waiver, so this move runs on the Michigan Department of Licensing and Regulatory Affairs — Bureau of Construction Codes (BCC), Plumbing's individual endorsement or equivalency review rather than a guarantee. Bring your Indiana license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
What's different between Indiana 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
Indiana to Michigan (this page): Licensure by endorsement.
Michigan to Indiana (the reverse move): Licensure by endorsement.
The route is the same in both directions.
- Does coming from Indiana matter?
Indiana gets Michigan's most common result: 41 of 50 origins (the other 49 states and DC) get the same one, so for most movers the origin does not change the answer.
The others get: no state license to transfer (9).
- Application fee
Michigan lists $40–$90 for an out-of-state applicant and Indiana lists $15–$30 for the reverse move; neither may be the full cost.
- Exam rules on record
Michigan and Indiana 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.
- Indiana (the reverse move): Indiana Code 25-28.5-1-19 (verified current as of 2026-01-01) provides that an out-of-state journeyman plumber 'shall without examination, be granted a license' by the Indiana Plumbing Commission IF the other jurisdiction's licensing requirements were substantially equal to Indiana's when the applicant was last licensed AND that jurisdiction grants Indiana licensees the same reciprocal privilege; the statute names no partner states and no official list of qualifying states was located, so an applicant must confirm eligibility with the Commission, and anyone who does not meet the substantial-equivalence/mutuality test must be approved by the Commission and pass the Indiana journeyman plumber examination

Frequently asked questions
Can I keep my Indiana plumbing license after I'm licensed in Michigan?
Yes — plumbing licenses in different jurisdictions run independently. Keep the Indiana credential active on its own renewal and continuing-education schedule and you hold both, which is common for plumbers working near a state line.
