Milwaukee County has no carport ordinance. As a detached accessory structure, a carport is exempt from the state Uniform Dwelling Code, so its permit, size, height, and setbacks are set entirely by your city or village zoning code.
Carports are not regulated by Milwaukee County. A freestanding carport is a detached accessory building, which the Wisconsin Uniform Dwelling Code exempts under SPS 320.05(4) (with the fire-separation exception of SPS 321.08(1)). So whether a carport is permitted, its size and height, how far it must sit from lot lines, and whether it may stand in a front yard are all set by the zoning ordinance of the city, village, or town under Wis. Stat. 62.23(7). Municipalities commonly require a zoning permit, limit carports to side or rear yards, and apply setback and coverage standards; some restrict metal or fabric carports. An attached carport is usually reviewed as part of the house. Confirm the rules with your municipality.
Installing a carport without the required zoning permit, exceeding local height or coverage limits, or placing it in a prohibited yard can bring forfeitures and removal orders. Placing it near a lot line may also implicate the state fire-separation rule.
