Erie County — county ADU rules and overlays

County ADU ordinance

Erie County, Ohio (Lake Erie shoreline tourism county; ~75,300 residents; county seat Sandusky; home of Cedar Point amusement park; 14 townships including Berlin, Florence, Groton, Huron, Kelleys Island, Margaretta, Milan, Oxford, Perkins, and Vermilion townships; incorporated places City of Sandusky, City of Huron, City of Vermilion (split with Lorain County), Village of Castalia, Village of Kelleys Island, Village of Milan, Village of Berlin Heights, and Village of Bay View) HAS adopted countywide rural zoning under O.R.C. Chapter 303 (Erie County is one of the minority of Ohio counties that operates county-tier zoning, alongside Lake County, Summit County, Geauga County, and a handful of others). The Erie County Zoning Resolution is administered by the Erie County Regional Planning Commission and the Erie County Building Department; it covers unincorporated parcels in townships that have not adopted their own Chapter 519 township zoning. Several Erie County townships (notably Perkins Township, which surrounds Sandusky and contains the Cedar Point causeway corridor, and Huron Township and Margaretta Township) have adopted their own township zoning resolutions under O.R.C. Chapter 519, which then displace the county resolution within those township boundaries. The Erie County Zoning Resolution does NOT explicitly use the phrase 'accessory dwelling unit' as a separately permitted use; second dwellings on a parcel are evaluated under the resolution's general single-family residential district provisions, which historically permit only one principal dwelling per zoning lot. An attached in-law suite that shares the main structure and lacks a separate utility connection is typically treated as a single dwelling unit, while a detached secondary dwelling generally requires either a lot split, a conditional use approval, or qualification as an agricultural-use exemption under O.R.C. § 303.21 (the Ohio agricultural exemption that immunizes farm-related dwellings on parcels of five or more acres from county zoning when used in connection with bona fide agricultural production).

County regulatory overlays

Federal (United States) — ADU-relevant rules and programs

Federal ADU law

The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.

Federal financing programs

Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.

Federal tax credits

There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.

Federal housing programs

HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
