Local enforcement of licensed plumbers preemption

SF 3574 preempts local governments from requiring additional licensing, bonds, or insurance for plumbers already licensed by the Minnesota state commissioner. It directly affects plumbers working in cities, towns, or counties that previously imposed local requirements beyond the state license, and local governments that enforced such rules. The key provision (section 326B.44, subsection b) states no city, county, town, or other local entity may demand extra licenses, certifications, or exams for state-licensed plumbers. This bill standardizes plumbing licensing across Minnesota by ensuring state-licensed plumbers face only state-mandated requirements. The bill is currently in the early stages of review (referred to the Labor Committee after introduction on February 17, 2026).
