Plumber License from Michigan to Idaho: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: Idaho Division of Occupational and Professional Licenses (DOPL) — State Plumbing Board ↗
A plumbing license transfers from Michigan to Idaho by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Idaho Division of Occupational and Professional Licenses (DOPL) — State Plumbing Board, verify your Michigan license, and meet Idaho's endorsement requirements. Idaho waives its journeyman plumber written examination for reciprocity applicants who hold an active journeyman license obtained BY EXAMINATION in Montana, Oregon, or Washington and who meet the experience and residency conditions ('No written examination shall be required for the reciprocal certificate when reciprocating from' these states); every other applicant must pass the IAPMO-based Idaho journeyman examination.

Verdict
Licensure by endorsement
Michigan is not among the states Idaho names for an automatic exam waiver, so this move runs on the Idaho Division of Occupational and Professional Licenses (DOPL) — State Plumbing Board's individual endorsement or equivalency review rather than a guarantee. Idaho waives its journeyman plumber written examination for reciprocity applicants who hold an active journeyman license obtained BY EXAMINATION in Montana, Oregon, or Washington and who meet the experience and residency conditions ('No written examination shall be required for the reciprocal certificate when reciprocating from' these states); every other applicant must pass the IAPMO-based Idaho journeyman examination. Bring your Michigan 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 changes, Michigan → Idaho
| Michigan (current) | Idaho (destination) | |
|---|---|---|
| Application fee | $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.) | Idaho DOPL journeyman plumber license fees are prorated and reciprocity applicants pay the standard application/license fee, but the exact figure could not be confirmed on a directly loaded DOPL fee schedule because every idaho.gov host was unreachable (connection refused) from the research environment; one search result cited a $147 three-year license fee and another cited roughly $29 license / $22 renewal — the two conflict, so no figure is asserted. Confirm on the DOPL fee schedule |
| Processing time | 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. | No board-stated processing time in weeks |
