South Dakota

Updated 11/11/2025

Overview

South Dakota follows a local adoption approach for residential code, 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. A statewide adoption of the NEC with state amendments is mandated.

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.
