In South Dakota, the extreme temperature fluctuations and significant snowfall during winter require robust insulation, durable exterior finishes, and foundation designs that can withstand freeze-thaw cycles. The state building code, which largely adopts the International Residential Code (IRC), must be adhered to, while local municipalities like Sioux Falls may have specific zoning ordinances concerning minimum lot sizes, setbacks, and accessory dwelling unit density. The prevailing housing stock often consists of single-family homes from various eras, requiring sensitive integration of new ADUs to maintain aesthetic coherence and property value.
