Off-Grid Living in Overton County, Tennessee

I'll be straight with you: Overton County, Tennessee is one of the more permissive places I've come across for off-grid living, at least on paper. According to the county's own permits and zoning page, Overton County does not have building codes or zoning restrictions for properties outside the Livingston city limits. That's a big statement, and it's the county itself saying it, not me interpreting a gap in the law.

Zoning and dwellings. Outside Livingston, there's essentially no county-level zoning to navigate. That means tiny homes, RVs used as residences, and unconventional dwellings aren't specifically restricted by the county, since the county says no zoning or building codes apply out there at all. I didn't find anything addressing tiny homes or RVs by name, so treat that as inherited from the "no restrictions" baseline rather than a confirmed green light for every scenario. Inside Livingston, you're under the town's own municipal code, which I haven't dug into here, so call town hall if that's your target property.

Building permits. Same story: no building codes enforced outside Livingston, per the county. The one exception is electrical work, which the state of Tennessee handles directly through its own permitting, obtainable online through the state's system, regardless of what the county does with zoning.

Septic. This is where the state steps back in. Tennessee runs septic permitting through TDEC (Tennessee Department of Environment and Conservation) statewide, and Overton is not one of the handful of counties (Blount, Davidson, Hamilton, and others) that administers its own program. So even though the county has waived zoning and building codes, septic systems still go through TDEC's regional process. I found no dry-cabin or composting-toilet exemption specific to Overton, so assume the state's standard rules (including NSF 41 for composting toilets) apply.

Greywater and rainwater. Neither has a county-specific rule that I could confirm. Greywater falls back to the state plumbing code framework, and I'd call that unclear until you check with TDEC or the county directly. Rainwater harvesting looks fine, since there's no restriction and the general "hands-off" posture of the county doesn't suggest any conflict.

Wells and utilities. Private wells are legal under state law and regulated through licensed well drillers, not the county. Overton County is carved up among a few utility districts (North Overton, West Overton) rather than one central authority. If your land falls inside one of their service areas and you sign up, their contracts govern things like cross-connection rules, but nothing suggests a mandatory hookup ordinance for the county as a whole.

Bottom line on disconnecting. With no countywide zoning or building code outside Livingston, nothing forces you onto the grid for power, water, or sewer out there. Septic is the one place the state keeps a real hand in, so budget time for that process even if everything else feels wide open.
