Do you need a license to work as a plumber in Michigan?
Yes. In Michigan, a plumbing contractor, master plumber, journey plumber or apprentice plumber must be licensed or registered under the plumbing article of the Skilled Trades Regulation Act, and only a licensed master or journey plumber may perform plumbing. A licensed master plumber must be in charge of the work, and the responsible plumbing contractor must obtain a permit. A plumbing contractor license requires holding, or employing as representative, a master plumber license. A license is not required for minor repair work or for a homeowner installing the homeowner’s own plumbing in a single-family dwelling under a permit. This is MCL 339.6107, 339.6111.
