Off-Grid Living in Stewart County, Tennessee

I'm Mike, and I've been digging into what it actually takes to live off-grid legally in Stewart County, Tennessee. This is one of the more permissive counties I've researched, but "permissive" doesn't mean "no rules" - it means the rules come from different places than you might expect.

Zoning: Stewart County has no countywide zoning and no planning commission. That's confirmed by Tennessee's own Department of Economic and Community Development data. In practice, this means unincorporated land in the county isn't governed by use-district restrictions the way it would be in a zoned county. The catch: the Town of Dover, the county seat, is a separate municipality with its own Codes, Planning & Zoning office. If your land is inside Dover town limits, none of the "no zoning" logic applies to you - you're under Dover's rules.

Building codes: This is the most important finding. Stewart County government's own site hosts a document confirming the county is an "opt-out" (non-code) jurisdiction under Tennessee's building code election law. Counties can choose to exempt themselves from statewide residential building code enforcement, and Stewart County has done so. That doesn't mean anything goes forever - even in opt-out counties, an owner can voluntarily ask the State Fire Marshal's Office to inspect a home to verify it meets state safety standards, which can matter for insurance or financing down the road.

Dwellings, tiny homes, RVs: I couldn't find a Stewart County-specific ordinance on tiny homes or RV occupancy. Given the opt-out building code status, I'd expect a lot of flexibility here, but confirm current practice with the county before you build.

Septic: This is where state authority takes over regardless of local zoning status. Tennessee's TDEC (Division of Water Resources) administers septic permitting statewide, and I could not find a dedicated Stewart County environmental health webpage. Any habitable structure will need an approved septic system - there's no rural or DIY exemption in state law.

Greywater and rainwater: No county-specific rules found for either. These fall back to Tennessee's general state framework, which is generally permissive for rainwater collection and for subsurface greywater irrigation systems.

Wells: No county well ordinance found. Wells statewide fall under Tennessee's Water Well Act, requiring a licensed driller, administered by TDEC.

Utilities: Going off the electric grid appears unrestricted at both county and state level. But cutting off from utilities doesn't get you out of the septic requirement - a habitable dwelling still needs an approved wastewater solution under TDEC rules.

Bottom line: Stewart County's lack of zoning and its opt-out building code status make it genuinely attractive for off-grid projects, but septic permitting is the one place the state will still require paperwork no matter how rural your parcel is. Always double check current status with the offices below, since opt-out designations and local practices can change.
