Sioux Falls adopts the IECC for residential and commercial energy efficiency under Ch. 33, but the city does not impose stricter local green building mandates beyond the state-adopted code baseline.
South Dakota and Sioux Falls Code Ch. 33 adopt the International Energy Conservation Code as the floor for new construction insulation, fenestration, and HVAC efficiency. The city does not currently mandate LEED, net-zero, or all-electric construction, reflecting the state preemption-light posture toward local mandates on energy. Sioux Falls Sustainability Plan promotes voluntary high-performance design, and Sioux Valley Energy and Xcel Energy offer rebates. Building Services confirms IECC compliance through plan review and field inspection at framing, insulation, and final stages.
Failure to meet IECC during inspections will block certificate of occupancy until corrections are made and reinspected by Building Services.
