South Dakota
Updated 3/15/2025
Overview
South Dakota follows a local adoption approach, meaning building codes are adopted and
enforced at the municipal level. There is no statewide mandated code, so each city, county,
or township may adopt its own version of building codes and apply local amendments.
Due to this localized administration, it is essential to consult with local municipal authorities to determine the specific codes and amendments applicable in your area.

Local Adoption
A local adoption model means that the state does not mandate uniform building codes,
leaving code adoption and enforcement entirely to local jurisdictions. Cities and counties
determine which codes to implement, leading to potential variations in regulations across
different areas within the state.
