Regulatory framework
The code baseline for Decatur County.
N/A for a current countywide 2026 code edition. No Decatur County building-code or countywide building-permit program was identified in the accessible official sources. The City of Oberlin code adopts the 2015 International Building Code for city projects; other municipalities may differ. Decatur County's sanitary-code materials indicate that wastewater requirements remain a separate local/state concern.
