Off-Grid Living in Champaign County, Ohio

I'll be upfront: Champaign County, Ohio is one of those places where the answer to "can I do this off-grid?" splits depending on which office you're asking. There's no countywide zoning code here, so land use rules come from whichever township or village your parcel sits in, while building, septic, and well permitting run through county-level offices. Worth sorting out early which bucket each question falls into.

Zoning is handled township by township (Wayne, Union, Adams, and so on) or by incorporated villages and the City of Urbana, each with its own zoning inspector, fee schedule, and rules. The Logan-Union-Champaign Regional Planning Commission keeps a directory of township contacts, but it's not a regulatory body itself. There's genuinely no single answer here, you have to call the specific township or village office for your parcel.

Dwellings, tiny homes, and RVs: I didn't find a Champaign County or township page that speaks directly to tiny homes or RV living as a primary residence. Ohio's state manufactured-home rules apply as a baseline (HUD-code homes must be allowed wherever conventional homes are), but occupancy permits, minimum size, and RV permanence rules are set locally by whichever township or village has jurisdiction. Confirm with that zoning inspector.

Building permits go through Champaign County Building Regulations, which enforces the state Residential Code of Ohio. If a township zoning inspector classifies a structure as agricultural rather than residential, it may be exempt from building code under Ohio law, but switching that use later to residential triggers a change-of-occupancy permit and full compliance. Manufactured home installs are separately permitted through Ohio Department of Commerce-certified inspectors, and the county recommends checking with local zoning too.

Septic is permitted and enforced by the Champaign Health District under Ohio's statewide sewage treatment system rules. They do site evaluations (useful before buying raw land), issue installation permits, and since 2015 Ohio has required septic owners to hold an operation permit, renewed on a set state cycle. Composting toilets aren't separately addressed, they likely fall under the same state framework, so ask the Health District directly.

Greywater systems fall under that same statewide sewage treatment framework, administered locally by the Health District, so they're permitted with the right approval.

Rainwater harvesting: no county-specific rule turned up, and cisterns are treated similarly to private water systems under state rules. This looks fine but isn't spelled out locally, so I'd confirm intended use with the Health District if it's for potable water.

Wells require a permit from the Champaign Health District before you dig, alter, or seal a private water system, per Ohio Administrative Code. No work should start before that permit is validated except in genuine emergencies.

Utility disconnection: I couldn't confirm any county or township rule requiring hookup to electric, water, or sewer. Habitability still comes back to meeting the state building code and having an approved septic and water system if you have plumbing.

Bottom line: this is a county where persistence pays off, call the right office for the right question, and don't assume one department's answer covers another's turf.
