Off-Grid Living in Trumbull County, Ohio

I'll be upfront: Trumbull County, Ohio is one of those places where the county itself does very little of the actual rule-making. When I dug into this, the biggest thing I found is that Trumbull County has no county-wide zoning code. The Trumbull County Planning Commission says so plainly on its own site, calling its role "advisory" and noting it has no authority over local zoning decisions. Only four townships (Brookfield, Mecca, Mesopotamia, and Vernon) currently have no zoning at all. Every other township, city, or village in the county sets its own zoning rules, so if you're eyeing a parcel here, your first call has to be to that specific local zoning office, not the county.

That local-control pattern carries through several of the dimensions that matter most to off-gridders. Dwelling type rules, whether an RV or tiny home can be a permanent residence, minimum square footage, all of that is a township/city/village call. I could not find a countywide standard, so confirm directly with the local zoning authority before you buy or build.

Building permits are a different story: the county Building Inspection Department enforces the state-adopted Ohio Building Code and Residential Code of Ohio, and you'll need both a local zoning permit and a county building permit for new construction, plus plan reviews for things like heating layout.

Septic, wells, and cisterns all run through the Trumbull County Combined Health District (TCCHD), which administers Ohio's statewide rules (OAC 3701-28 and 3701-29, ORC 3701.344-347) locally. Septic permits go through TCCHD and are tied to a specific validity period from issuance. Private wells also go through TCCHD, and notably, septic approval has to happen before the well/plumbing permit is issued. Cisterns and rainwater harvesting get handled under the same private water systems program, with a completion form specific to cisterns. Greywater doesn't appear to have its own distinct county application, I'd assume it falls under the same sewage treatment permitting TCCHD runs, but that's not confirmed, so ask them directly.

The murkiest area is living fully disconnected from utilities. I found no Trumbull County ordinance mandating hookup to public water, sewer, or electric. But one health district form for existing septic systems mentions needing a letter from the township, city, or village granting permission for "temporary installation of a structure on the property and occupancy," which tells me local governments do sign off on temporary or off-grid living setups case by case rather than having a blanket policy either way.

Bottom line: this county pushes almost every meaningful decision down to the township or municipal level, so plan on multiple phone calls, not just one, before you commit to a piece of land.
