Do I need a permit to build a pole barn in Michigan?
Michigan farm buildings used for agricultural purposes on working farms are exempt from the State Construction Code under Michigan Act 230 of 1972 (State Construction Code Act). Michigan exempts farm buildings used for agricultural purposes from the State Construction Code under certain conditions. Structures used exclusively for farming on a working farm may not require a building permit, though local townships may have their own requirements. For non-agricultural structures — workshops, garages, barndominiums — permits are required under the Michigan Building Code, issued by your local township or city.
