Off-Grid Living in Erie County, Ohio

Erie County, Ohio is a patchwork when it comes to off-grid living, and I want to be upfront about that before anything else. There's no single county building or zoning department here. The Erie County Department of Planning and Development staffs the Erie Regional Planning Commission and handles zoning changes, subdivisions, and lot splits for unincorporated areas, but actual zoning authority and building permit issuance belongs to each township (Groton, Vermilion, Perkins, etc.) and municipality (Sandusky, Vermilion), each running its own zoning map and, in some cases, contracting out building department services (Huron Township does this for several jurisdictions). Health and environmental matters, by contrast, are handled countywide by the Erie County General Health District. So depending on what you're asking about, the "who do I call" answer changes.

Zoning and raw land: Whether you can occupy or build on a parcel depends entirely on which township or city it sits in. Groton Township, Vermilion Township, and others each have their own zoning districts (AG/RES, R-1, R-2, and Vermilion Township's own Agricultural/Rural Residential district). I could not find a countywide baseline, so confirm with the specific township zoning inspector.

Tiny homes, RVs, alternative dwellings: I didn't find a specific Erie County or township page spelling out RV or tiny-home occupancy standards. Ohio's state baseline requires HUD-compliant manufactured homes be allowed wherever single-family homes are allowed, but township zoning resolutions would set the actual rules for RVs and tiny homes as permanent dwellings. Ask the township zoning office directly.

Building permits: No county-level permit office exists. Huron Township enforces the Ohio Building, Mechanical, Plumbing, Electrical, Existing Building, and Energy Codes for jurisdictions under contract with it, and requires a zoning certificate from the local jurisdiction before a building application. Sandusky follows the same state codes within its city limits but issues its own permits.

Septic and composting toilets: This is handled countywide by the Erie County General Health District, which reviews site/soil evaluations and issues permits to install septic systems under state sewage treatment rules. If public sewer becomes available and the county issues a notice to connect, you generally can't keep running a septic system or privy.

Greywater and rainwater: Both fall under the state's Sewage Treatment System rules and the state's private water system rules (OAC 3701-28), administered locally by the Erie County Health District. I did not find an Erie-specific ordinance narrowing or expanding these.

Wells: Countywide, administered by the Health District. A permit is required to install, alter, or seal a private water system, per state rule OAC 3701-28-03(A), which the county implements directly.

Utility disconnection: Not clearly addressed for electric or water. But for sewer specifically, if a notice to connect to public sewer is issued and you don't comply, the county can pursue enforcement through the Health District and prosecutor and start charging a minimum sewer bill. So full independence from sewer isn't guaranteed if public sewer reaches your parcel.

Bottom line: for zoning and building, everything is local to your township or city. For septic, wells, and water, it's the county Health District. Call ahead before you assume anything.
