Do I need a permit for shed or accessory structure in Unincorporated Stearns County?

It depends. Whether shed or accessory structure needs a permit in Unincorporated Stearns County comes down to the details of your project.

Minnesota's own permit rule (Minn. R. 1300.0120, subp. 4) exempts one-story detached accessory structures used as tool or storage sheds, playhouses, and similar uses up to 200 square feet from the building permit; larger sheds need a building permit where the code is enforced. The 200 square foot exemption covers only the building permit; plumbing, electrical, and mechanical permits are still required, and zoning, setback, and shoreland rules still apply. Whether a building permit is issued at all depends on whether the city, township, or county covering the address has adopted and enforces the State Building Code (Minn. Stat. 326B.121); check the DLI local code lookup first. 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.
