Adams County, Ohio (rural Appalachian county on the Ohio River; ~27,500 residents; county seat West Union; 15 townships including Bratton, Brush Creek, Franklin, Green, Jefferson, Liberty, Manchester, Meigs, Monroe, Oliver, Scott, Sprigg, Tiffin, Wayne, and Winchester; incorporated places West Union (village), Manchester (village), Peebles (village), Seaman (village), and Winchester (village)) does NOT operate a countywide zoning ordinance and has not adopted county-tier zoning under O.R.C. Chapter 303. Ohio is a home-rule state under Article XVIII of the Ohio Constitution; counties may adopt county zoning under O.R.C. Chapter 303 but most do not (Lake County is the canonical Ohio county that does), and Adams County has not. Townships in Adams County may adopt township-tier zoning under O.R.C. Chapter 519, but as of 2026-05 most Adams County townships have NO township zoning resolution in force. Where neither county nor township zoning exists, a parcel in unincorporated Adams County is effectively unzoned for land-use purposes; the Ohio Residential Code (OAC 4101:8) still governs construction standards for any dwelling, including an ADU, and the Adams County Health Department still governs septic permits, but there is no local zoning prohibition on a second dwelling on a parcel. ADU permissibility in unincorporated Adams County therefore turns on (1) whether the parcel is in a township with zoning (a minority), (2) whether the parcel is inside village limits (in which case the village's zoning applies), and (3) whether the parcel can support a second septic field under OAC 3701-29 capacity rules.
