Off-Grid Living in Scioto County, Ohio

I'll level with you right away: Scioto County, Ohio is one of those places where the answer to "can I do this off-grid?" depends heavily on where exactly your land sits, because the county itself has no unified zoning code. Ohio law hands zoning authority to individual townships (or to the City of Portsmouth if you're in city limits), so your first call really should be to your township trustees or zoning office, not the county.

Zoning and raw land. There's no countywide zoning ordinance in Scioto County. Some townships, like Valley Township, have adopted their own zoning resolutions with a zoning official and appeals board; others may have none at all. Portsmouth runs its own planning and zoning department separate from the county. I can't tell you what's allowed on your specific parcel without knowing the township, so that's step one.

Dwellings, tiny homes, RVs. I found nothing at the county level addressing tiny homes or RV living as a residence. This falls entirely to township zoning resolutions or Portsmouth's code, layered on top of Ohio's baseline manufactured-home protections. Ask your township zoning office directly.

Building permits. Ohio enforces the Residential Code of Ohio through locally certified building departments. Inside Portsmouth, the city's own building department handles this. Outside city limits, it runs through whatever certified building department has jurisdiction over your township, an important thing to confirm before you build anything.

Septic and composting toilets. This one's clean and countywide: the Scioto County Health Department's Environmental Health Division permits and inspects all sewage systems under state rules (Ohio Administrative Code 3701-29). Since 2015, all new or replacement systems get enrolled in an operation and maintenance program automatically. Composting toilets aren't separately addressed on the SCHD site I reviewed, so treat that as unconfirmed and ask them directly.

Greywater and rainwater. Neither has a Scioto County-specific page in my research. Greywater likely falls under the state's OAC 3701-29 framework administered by SCHD, and rainwater cisterns for drinking water appear to fall under the county's private water systems program, but neither is spelled out clearly. Call SCHD Environmental Health before you design a system.

Wells. This is well-documented: a county health department permit is required before installing or altering any private water system, including wells, ponds, or hauled water storage tanks, under Ohio Revised Code 3701.344. If you're doing your own well work, registration and surety bonding rules kick in depending on the work performed.

Utility disconnection. I found no county rule requiring hookup to electric, water, or sewer for occupancy. The Residential Code of Ohio still governs what makes a dwelling "habitable" through whichever building department has jurisdiction, but that's a code compliance question, not necessarily a mandatory-hookup rule. Confirm with your building department.

Bottom line: Scioto County splits authority between townships (zoning), certified building departments (construction), and the county health department (water and septic). Don't assume county-level answers apply until you've checked your township.
