Do I need a permit for shed or accessory structure in Unincorporated Ontonagon County?
Unincorporated Ontonagon County does not issue residential building permits. Ontonagon County has no county construction code program. The Statewide Jurisdiction List (Rev. 8/21/2026) shows the State of Michigan Bureau of Construction Codes enforcing building in the Village of Ontonagon and in Bohemia, Carp Lake, Greenland, Haight, Interior, Matchwood, McMillan, Ontonagon, Rockland and Stannard townships, while Bergland Township runs its own building program. BCC Building Trades Section: 517-241-9313, bccpermits@michigan.gov.

It depends. Whether shed or accessory structure needs a permit in Unincorporated Ontonagon County comes down to the details of your project.
The Michigan Residential Code (R 408.30505) exempts from a building permit a one-story detached accessory structure with a floor area of 200 square feet or less; larger or taller structures need a building permit. The exemption covers the building permit only; wiring or plumbing in the shed still needs its own trade permit, and local zoning rules on setbacks and zoning permits still apply. Check the BCC Statewide Jurisdiction List first: the permit may come from the city, village, or township, the county, or the state Bureau of Construction Codes. A shed that will have electricity, plumbing, or a permanent foundation falls outside the usual small accessory building exemption, which generally covers simple unpowered structures only. Electrical and plumbing work each normally require their own permit and inspection even when the structure itself would have been exempt, and many jurisdictions require a licensed electrician or plumber to pull them. Zoning setbacks, height limits, and lot coverage are reviewed separately from the building permit, so confirm placement with your local department before the shed is delivered or poured.
