Licking County (county seat Newark; ~180,000 residents in east-central Ohio, immediately east of Columbus / Franklin County) has NOT adopted a county-tier zoning resolution under O.R.C. Chapter 303. As a Dillon's Rule state with the home-rule amendment (Ohio Const. Art. XVIII), Ohio counties may not zone unincorporated territory unless they affirmatively adopt a county zoning resolution by board action and (in most cases) public referendum; Licking County has never done so. Land use in unincorporated Licking is therefore set entirely by individual township zoning resolutions under O.R.C. Chapter 519. Twenty-three of the county's twenty-five townships have adopted zoning resolutions, several driven by spillover development pressure from the Intel 'Silicon Heartland' semiconductor megafab under construction just over the county line in Jersey Township, Franklin County; the remaining townships (historically Mary Ann Township and a small number of others) are unzoned, meaning ADU permissibility there is essentially unregulated by zoning (still subject to county building code, septic, and floodplain administration). The Licking County Planning Commission (LCPC) provides subdivision review, GIS, and advisory planning services but does not enforce a county-tier zoning code. ADU permissibility, parking, owner-occupancy, and size limits are set by each township's resolution or by each incorporated municipality (City of Newark, City of Pataskala, City of Heath, City of Reynoldsburg portion, Village of Granville, Village of Hebron, Village of Buckeye Lake, Village of Johnstown, Village of Alexandria, Village of Hanover, Village of Kirkersville, Village of Saint Louisville, Village of Utica, Village of Gratiot).

State-floor overlay: No Ohio statewide ADU preemption is in force as of 2026-05-20 (see ohio.json stateAduLaw). Authority over ADU permissibility rests with each township and incorporated municipality.
