Can you put a tiny home in South Dakota?
Current tiny-home-on-wheels and ADU rules for South Dakota, sourced and dated — plus verified local builders.
GENERALLY ALLOWED
South Dakota — Low population, light rural zoning, with real named counties (verified 2026-08)
Tiny home on wheelsNo statewide tiny-home-on-wheels law; most rural counties have minimal zoning outside incorporated towns, similar to North Dakota. Where a minimum applies at all, the commonly cited figure is 190 sq ft plus 50 sq ft per additional occupant, under an amended 2015 IRC baseline.
ADU / accessory unitMinnehaha County (home to Sioux Falls) permits tiny homes on permanent foundations in forestry and agricultural zones, provided they are not the primary residence on the lot. Pennington County (Rapid City area) requires a permanent foundation and standard code compliance. Spearfish, in Lawrence County, has specifically adopted tiny-home-friendly building codes rather than relying on general accessory-structure rules.
Minimum square footageCommonly 190 sq ft plus 50 sq ft per additional occupant where a local minimum applies
Foundation requirementWinter climate adds foundation-frost-depth requirements in most of the state
Local notesMinnehaha, Pennington, and Lawrence (Spearfish) counties are the three most concrete, named starting points in the state.
!Zoning is set by your specific city or county, not the state as a whole. Use this as a starting point, then confirm with the local building or planning department before you buy land or start a build. Not legal advice.
