Regulatory framework
The code baseline for Marshall County.
Marshall County enforces its Zoning Ordinance effective June 30, 2026, including land-use, siting, setback, driveway, occupancy, and project-specific requirements. No currently adopted countywide structural IBC or IRC edition was verified; the ordinance references Uniform Building Code compliance for manufactured/mobile housing. For covered new nonresidential construction where no local code applies after July 1, 2026, South Dakota law designates the 2024 IBC as the state minimum, subject to statutory exclusions.
