Off-Grid Living in Jackson County, Tennessee
Jackson County, Tennessee has no discoverable county-specific zoning, building, or septic office documentation online, so most rules default to Tennessee's state baseline, with septic permitting run through TDEC. Several key questions (zoning existence, building code enforcement, local septic office) remain unconfirmed and require a direct call to the county.
Is it legal to live off-grid in Jackson County, Tennessee?
There is no outright ban on living off-grid in Jackson County, Tennessee - it is possible, but the local rules are not all documented online. Zoning and land use are not clearly documented online, so confirm it locally, putting a cabin, tiny home, or RV on raw land is not clearly documented online, so confirm it locally, and building permits are not clearly documented online, so confirm it locally. Plan around septic/wastewater (restricted) and disconnecting from utilities (set locally and vary by area). Because these rules are set locally, confirm the specifics with Jackson County before you buy land or build.

I'll be upfront: Jackson County, Tennessee is a small, rural county (seat: Gainesboro, pop. roughly 11,600), and it simply doesn't have much of a web presence when it comes to zoning, building, or environmental health departments. I looked for an official county zoning ordinance, a building permit office, and a septic/health department page on the county's own site and on Municode/eCode360, and came up empty. I want to be honest about that gap rather than paper over it with guesses.
Zoning: I could not find a countywide zoning ordinance or zoning map for Jackson County. Many small rural Tennessee counties simply don't have zoning at all, and that appears consistent with what I found (or rather, didn't find) here. If that's the case, raw land use would be governed mainly by septic/health rules and any state building/fire codes rather than a zoning code. Confirm directly with the county.
Dwellings, tiny homes, RVs: No county-specific ordinance found. Tennessee's building code (including any Appendix Q tiny-home provisions) only applies where a county has opted in, and I could not confirm whether Jackson County has done so. RVs are typically treated as temporary rather than permanent dwellings under the state default, but this isn't confirmed locally.
Building permits: No Jackson County building department or permit page turned up. Tennessee law lets counties opt out of enforcing the state residential building code for one- and two-family homes, and it's not confirmed whether Jackson County enforces any code at all. Call the county to find out.
Septic: This one is actually state-controlled. Tennessee Code Title 68, Chapter 221, Part 4 governs subsurface sewage disposal, administered by TDEC. Some counties have been moved to a direct online TDEC application system rather than a local health department office; whether Jackson County has a local septic office or routes everything through TDEC's statewide portal isn't confirmed. Composting toilets aren't exempt from this permitting scheme as far as I can find.
Greywater: No county guidance found; state plumbing code technically allows subsurface greywater irrigation, but enforcement is inconsistent statewide and there's nothing county-specific to add clarity.
Rainwater harvesting: Nothing restricts this at the state or county level, so it's permitted.
Wells: Governed by Tennessee's Water Well Act; must use a state-licensed driller. No Jackson County-specific well ordinance or addressing requirement was confirmed.
Utilities: No mandatory-connection ordinance found. The county does list a wastewater plant contact, but whether hookup is mandatory near county sewer lines isn't confirmed. Grid-electric disconnection is unrestricted under state law.
My honest bottom line: for Jackson County, a phone call to the county government is going to get you further than the internet will.

Septic systems are governed by state law (Tennessee Code Title 68, Chapter 221, Part 4) and administered by TDEC.

Yes. Rainwater harvesting is unrestricted under Tennessee state law and nothing at the county level changes that.

I could not locate a dedicated building department page for the county. Start with the general Jackson County Government line, (931) 268-9888, and ask them to direct you.
