Zoning & Permits
South Dakota does not have mandatory statewide residential building codes. However, if a local jurisdiction adopts building code ordinances, they must use the 2021 International Building Code (IBC) for commercial buildings, though local amendments are permitted. The UpCodes South Dakota Building Codes resource provides information on state regulations. Many municipalities have adopted the 2021 International Residential Code (IRC). Contact your local building department for specific requirements as codes are enforced at the local level only.
Off-Grid & Rural Builds
For rural builds not connected to public sewer, onsite wastewater systems (septic systems) are regulated by the South Dakota Department of Agriculture and Natural Resources under Administrative Rules Chapter 74:53:01. Permits are required for all septic system installations or repairs. Systems must be installed by certified installers who have passed state certification. The state maintains a list of certified installers for public use. Approximately 25% of South Dakota residents rely on onsite wastewater systems.
Energy Code & Efficiency
South Dakota does not have a mandatory statewide energy code. The 2009 International Energy Conservation Code (IECC) is adopted as a voluntary standard for residential buildings under state law. Local jurisdictions may adopt energy requirements without state approval, though only larger jurisdictions have elected to do so. The Building Codes Assistance Project South Dakota provides information on energy code adoption status. If a local energy code is adopted, enforcement occurs at the local level.
Local Zoning Tools
Zoning in South Dakota is administered entirely at the municipal and county level. Each jurisdiction enforces its own zoning ordinances for dimensional requirements, setback distances, and land use regulations. There are no statewide zoning requirements. Contact your local planning or zoning department for site-specific requirements for your property. Cities like Sioux Falls, Rapid City, and Aberdeen all have their own local building codes and zoning requirements that must be followed.
Tip
If you're unsure about your parcel's status—whether it requires septic system approval through DANR, falls under local building code jurisdiction, or needs specific foundation requirements for South Dakota's climate extremes—contact your local building department, county planning office, or DANR directly. In South Dakota, requirements vary significantly by jurisdiction since codes are enforced locally. The resources above are a great place to start.
