Off-Grid Living in Chester County, Tennessee

I've been digging into Chester County, Tennessee for anyone thinking about building or living off-grid there, and I want to be upfront: this is one of those counties where the official paper trail thins out fast once you get past zoning and building codes. Here's what I could actually confirm, and where I hit walls.

Zoning is more present here than in a lot of rural Tennessee counties. Chester County Building and Zoning has covered the whole county since 2017, and the county also lets the City of Henderson run zoning and permitting for its own planning region just outside city limits. So depending on where your land sits, you're dealing with either the county department or Henderson's city department, not a free-for-all with no oversight.

Building permits are required. The county adopted the 2018 International Residential Code and actively enforces it, updating every so often as the state directs. This isn't a county that's opted out of code enforcement, so plan on pulling permits for a conventional structure.

Tiny homes, RVs as dwellings, Appendix Q: I couldn't find anything county-specific here. Tennessee lets counties decide their own stance on Appendix Q (the tiny-home-friendly code provisions), but Chester County's position isn't published anywhere I could find. You'd need to call the Building and Zoning Department directly to find out how they'd classify a tiny home or RV-as-residence.

Septic is required by state law, administered through TDEC for a septic system construction permit. Chester County doesn't appear to run its own environmental health department (unlike bigger counties such as Shelby or Davidson), so this likely falls to a TDEC regional field office, but I couldn't confirm which one specifically serves Chester County. Composting toilets aren't addressed locally either, so I'd assume the state baseline (typically wanting NSF 41 certification) applies until you confirm otherwise.

Greywater and rainwater have no county-specific rules that I could find. Tennessee doesn't restrict rainwater collection statewide, so that's probably fine. Greywater reuse is technically allowed under the state plumbing code with restrictions, but how strictly that's enforced locally is unclear.

Wells are governed by the statewide Water Well Act, requiring a licensed driller. No Chester County water authority page exists that I could locate, so there doesn't seem to be a local overlay on top of state rules, but I can't be fully certain.

Utility disconnection: nothing on the books that I found mandates hooking rural county parcels up to water or sewer. Henderson runs its own utility department for in-city customers, but if you're out in the unincorporated county, that's not really addressed anywhere official.

Bottom line: zoning and building codes are real and enforced here, but a lot of the off-grid specifics (septic administration, wells, greywater, tiny homes) just aren't published, so a phone call before you buy land will save you headaches.
