South Dakota Tiny Home Standards Through State Building Code

South Dakota lacks a uniformly adopted statewide residential building code, leaving most construction standards to municipalities and counties. However, manufactured and modular housing fall under SDCL Chapter 34-34A, which adopts HUD federal standards and requires installation inspections. Tiny houses on wheels generally must be titled and registered as recreational vehicles or park trailers under SDCL Title 32 if they exceed certain size thresholds. Permanent foundation tiny homes must meet whatever local code the city or county has adopted, often the International Residential Code Appendix Q for small dwellings.

Operating a tiny home on wheels as a permanent residence without proper RV registration or zoning approval may result in code enforcement action and removal orders by local authorities.
