Regulatory framework
The code baseline for McPherson County.
McPherson County enforces Zoning Ordinance 2024-1 and its 2025 amendments in the unincorporated county, except the mapped area generally within one mile of Eureka under city jurisdiction. No general county structural IBC or IRC edition was verified; the ordinance specifically requires cannabis establishments to comply with the IBC under SDCL 11-10. For other covered new nonresidential work after July 1, 2026 where no local code is adopted, the 2024 IBC is the state minimum subject to statutory exclusions.
