Building Energy Code
Quick Summary
South Dakota does not have a statewide mandatory energy code, but if your local jurisdiction has adopted one, it will apply to new residential construction in your area. If you're buying or building a new single-family or multifamily home (four units or less), the builder or seller must provide you with an energy efficiency disclosure form for the property.

Program Summary
Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites. A mandatory energy code is not enforced at the state level. If a local energy code is adopted, it is enforced at the local level. Builders or sellers of new residential buildings (single-family or multifamily residential of four units or less) are required to provide a disclosure form with information regarding the energy efficiency of the building. Currently all state facilities are contractually required to be built to ASHRAE 90.1-2007.
