Gahanna

Franklin County (state-capital county; ~1,326,000 residents — Ohio's most populous county; encompassing Columbus, Westerville, Dublin partial, Worthington, Bexley, Whitehall, Reynoldsburg, Gahanna, Hilliard, Upper Arlington, Grove City, Grandview Heights, New Albany, Pickerington partial, Canal Winchester partial, and a substantial fraction of unincorporated Franklin in townships including Sharon, Norwich, Washington, Madison, Truro, Hamilton, Mifflin, Plain, Blendon, Clinton, Perry, Pleasant, Brown, Jefferson, Franklin, Prairie, Jackson, and Marion) regulates land use in unincorporated areas through township-tier zoning under Ohio Revised Code Chapter 519 (Township Rural Zoning). Ohio is a Dillon's Rule state with home-rule for charter municipalities under Ohio Const. Art. XVIII. Counties may not directly zone unincorporated areas in Ohio (with exceptions for Lake County and a few others); zoning in unincorporated Ohio is performed by the township under ORC 519, with county Planning Commissions providing advisory review. Franklin County's Economic Development and Planning Department coordinates planning across the county and provides advisory review of township zoning under ORC 519.04. ADU regulation in Franklin County is therefore primarily township-tier and city-tier; the County's role is limited to advisory planning, the Franklin County Auditor (assessment), the Franklin Soil and Water Conservation District, and the Franklin County Public Health for septic permitting.
