State-Level HVAC and Building Code Framework in South Dakota

South Dakota utilizes a decentralized approach to building codes, meaning there is no single, uniform building code enforced statewide by a central agency. Instead, the adoption and enforcement of building codes, including those for HVAC systems, are largely handled at the local municipal or county level. When local jurisdictions choose to adopt building ordinances, they are generally guided by the International Code Council (ICC) standards, such as the International Mechanical Code (IMC) and the International Fuel Gas Code (IFGC).
