Do you need a permit for a pole barn in Michigan?
Michigan enforces the Michigan Building Code (MBC), based on the IBC, administered by local building departments. Michigan Compiled Laws § 125.1510 exempts agricultural buildings used for farming operations from the state construction code, provided they are not used for residential purposes. All non-agricultural pole barns — garages, workshops, barndominiums, commercial structures — require a permit from the local municipality or county.
