Moving to Minnesota as a journeyman plumber: every state's rule

Minnesota issues a statewide Journeyworker Plumber license through the Department of Labor and Industry (DLI); DLI's license-types page states the license 'authorizes the individual to work statewide', and no city-issued plumber licenses appear on DLI's pages (DLI also issues a Restricted Journeyworker license limited to towns under 5,000). A new applicant must first pass DLI's written journeyworker exam ($50 exam fee), and is eligible to sit it after a registered apprenticeship, four years (1,750 hours per year, 7,000 hours) of practical experience as a DLI-registered unlicensed plumber (Minn. Stat. 326B.47, subd. 2), two years under a Minnesota restricted license, or by holding a current plumber's license from another state that requires at least four years of experience and an exam. Journeyworker plumbers licensed by examination in North Dakota or South Dakota may be licensed without the Minnesota exam under DLI's reciprocity page. Licenses expire December 31 of odd-numbered years; renewal is $53 and requires 16 hours of continuing education, at least eight on the State Plumbing Code (2020 Minnesota Plumbing Code, Minn. R. ch. 4714).
