Shed Installation · Pennington County, South Dakota
In Pennington County, a Shed Installation under 400 sq ft generally does not require a building permit. At or above 400 sq ft, a permit is required.
The county's own Building Code and Construction Ordinance exempts an accessory structure of 400 square feet or less from building inspection requirements, a notably higher threshold than Rapid City's own 120-square-foot exemption within its city limits despite both jurisdictions sharing the same general metro area; a Rapid City resident and an unincorporated Pennington County resident building the identical 300-square-foot shed would face different outcomes purely based on which side of the city limit the parcel sits on. The county's ordinance separately defines a "Construction Permit" as distinct from a building permit specifically for excavating, clearing, or other land-disturbing activity, a permit category that can apply to shed-site preparation independently of the building exemption itself. Building permits in Pennington County are handled under the Pennington County Planning Department (unincorporated areas) building code (IRC International Reside). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Pennington County Planning & Zoning.
