Regulatory framework
The code baseline for Buchanan County.
N/A—the current county materials identify and enforce the Buchanan County Zoning Order, including a 2026 amendments section, but do not identify a current International Building Code edition. The county building-code dataset dated February 23, 2026 reports no county energy or residential code adoption. The zoning order applies in the unincorporated area; incorporated municipalities may have separate codes.
