Yankton Building Department | Permits, Inspections & Contact

The City of Yankton’s Community and Economic Development Department issues building permits and administers building services inside city limits and the City’s extraterritorial jurisdiction. Yankton County Planning and Zoning separately handles permits for property in the county’s unincorporated area; a county application does not replace the City permit for a Yankton address.

Yankton building permits and plan review

Yankton requires a building permit before new construction, additions, alterations, repairs, demolition, moving structures, and other listed work. The City asks applicants for a scaled plot plan, legal description, floor plan, wall sections, elevations, contractor information, project cost, and mechanical or plumbing plans when requested. Separate plumbing and stormwater permits may apply.

The City has adopted the 2021 International Building, Residential, Existing Building, Mechanical, and Fuel Gas Codes, plus the listed electrical, accessibility, and plumbing standards, with local amendments on file in the Community and Economic Development office. The public documents page provides building permit applications, permit information, zoning maps, and current permit reports.

Inspections, occupancy, and code compliance in Yankton

Building inspections must be coordinated with the Building Official while work remains accessible. Yankton identifies Gregg Homstad as Building Official at (605) 668-5253 and Jacob Olson as Building and Code Inspector at (605) 668-5259. Final inspection and any certificate-of-occupancy or change-of-use approval should be confirmed for the project before the structure is occupied or opened to the public.

The City’s building, code-enforcement, floodplain, stormwater, and zoning approvals are related but separate. A project in a special flood hazard area may need a floodplain development permit even where a building-permit exemption might otherwise apply.

Yankton zoning and county boundary note

Yankton administers zoning and development review within its city and extraterritorial jurisdiction. The county’s official planning page states that building permits are required for structures and exterior remodeling in unincorporated Yankton County. Confirm the exact boundary, zoning map, and applicable floodplain authority before choosing the City or County process.
