Regulatory framework
The code baseline for Turner County.
Turner County administers its 2008 Revised Zoning Ordinance, as subsequently amended, in unincorporated rural areas; incorporated cities handle their own permitting and zoning. No separate county-adopted structural model-code edition was verified. For covered new nonresidential work begun after July 1, 2026 where no local structural code applies, South Dakota's statutory design baseline is the 2024 International Building Code, subject to exclusions for residential structures, manufactured/mobile homes, farmsteads, and accessory farm buildings. State electrical, plumbing, and other trade requirements remain separate.
