Regulatory framework
The code baseline for Sanborn County.
Sanborn County Planning & Zoning administers county building permits and zoning processes, but no current locally adopted structural-code edition was published or verified. For covered new nonresidential construction begun after July 1, 2026, South Dakota's statutory baseline is the 2024 International Building Code, subject to statutory exclusions; state electrical, plumbing, and other trade requirements remain separate.
