Summary
Michigan's Residential Code (adopted statewide) requires a building permit for any detached accessory structure larger than 200 square feet. Sheds 200 sq ft or smaller are exempt from a state building permit but must still meet the zoning rules of the Oakland County municipality. Typical Oakland County standards: minimum 5 ft setback from side/rear lot lines, 10 ft separation from the principal dwelling, rear-yard only, and one-story max height (commonly 14–15 ft).
A building permit is not required for Detached Accessory Structures 200 sq. ft. or less, however, they shall comply with the following: Structures shall be more than 10 feet from the main building or any other Accessory Structure. Structures may be located in the side or rear yards of the property only, no closer than 5 feet from the property line and not in the front yard or within an easement. The maximum height above grade shall not exceed 1 story and 14 feet with a roof pitch less than 4/12 and 16 feet with a roof pitch greater than 4/12.
Full Breakdown
The Michigan Residential Code (MRC), enforced by every Oakland County municipal building department, sets the 200 sq ft permit threshold. ' Pontiac Zoning Ordinance restricts accessory structures to rear yards behind the principal building, with a 15-foot height cap and combined accessory floor area not exceeding 50% of the principal building's total floor area. Most Oakland County jurisdictions also require a zoning compliance permit for sheds under 200 sq ft (no building permit, but a zoning sign-off). Snow-load and frost-depth requirements (42-inch footing depth for permitted structures) reflect Southeast Michigan's freeze line.
Violations & Fines
Unpermitted shed over 200 sq ft: building department stop-work order, double-permit-fee penalty, and possible municipal civil infraction ($100–$500). Setback or rear-yard violation: zoning citation and order to relocate or remove the shed at the owner's expense. Building in a side yard, easement, or front yard typically requires complete removal. Encroachment into a recorded easement can also expose the owner to private suit by utility/drainage holders.
