Plumbing license reciprocity by state · Pair verdict
Your Illinois license, Minnesota's rules. This page computes the pair the boards leave you to guess at — the full checker adds your license status and level.
No endorsement
Exam-free reciprocity ONLY with North Dakota and South Dakota (DLI / Minn. Stat. 326B.48). Conditions: license obtained by examination at state level in the qualifying state, held at least 1 year, current and in good standing, applicant has not failed the same or greater class of Minnesota exam, and is not under an order to deny/suspend/revoke in Minnesota. Reciprocity application/exam fee $50; on approval the applicant has 180 days to pay the license fee. Minnesota license holders who have not renewed within 2 years after expiration do not qualify through reciprocity and must retest.
Minnesota's journeyman gate, for the exam route: 7,000 hours with category minimums · exam $50. One rule outranks the pair: a lapsed Illinois license endorses nowhere — reinstate at home first.
Rules as published by Minnesota Department of Labor and Industry (DLI) — Plumbing Board, checked October 22, 2026. Confirm with the board before you apply.
