Scott County, MN Accessory Structures: Shed & Carport Rules (2026)

Minnesota Rules 1300.0120, subpart 4, exempts a one-story detached accessory structure of 200 square feet or less from the building permit. That exemption reads the same in unincorporated Scott County and in Shakopee, Savage, and Prior Lake. It does not waive zoning: the county allows one accessory building up to 200 square feet without meeting setbacks, but lot-coverage limits, larger buildings, and placement rules still apply, and cities set their own. Running power to a shed triggers a separate electrical permit. Given Scott County's 42-to-60-inch frost depth, a frost-protected or pier foundation is wise to prevent heave.
