Minnesota master plumber · “Master Plumber”
Statewide license
Issued by Minnesota Department of Labor and Industry (DLI), Plumbing Board
Minnesota issues a statewide, person-held Master Plumber license through DLI; the license 'authorizes the individual to perform plumbing statewide', and a separate Plumbing Contractor license (a business license that must have a licensed master plumber as its responsible individual and carry a bond, general liability and workers' compensation insurance under Minn. Stat. 326B.46) is not covered here. DLI also issues a Restricted Master Plumber license limited to cities and towns under 5,000. A new master applicant must pass DLI's written master plumber exam ($50 exam fee) and is eligible to sit it after at least one year of practical experience as a licensed journeyworker plumber, with a current master plumber license from another state whose requirements DLI determines are equivalent to Minnesota's, or with a Minnesota restricted master license plus five years in business as a plumbing contractor. Master plumbers licensed by examination in North Dakota or South Dakota may be licensed without the Minnesota exam. Licenses expire December 31 of odd-numbered years; renewal is $93 and requires 16 hours of continuing education, at least eight on the State Plumbing Code.
