Off-Grid Living in Scott County, Tennessee

I'll be upfront: Scott County, Tennessee is one of those places where the honest answer to a lot of off-grid questions is "nobody has written that rule down yet." Let me walk through what I found digging into official sources.

Zoning. Scott County, as of my research, has no adopted countywide zoning ordinance. County leadership (the county mayor and board of commissioners) has reportedly been discussing whether to create one, but that's still in the talking stage, not law. Practically, that means raw land in the unincorporated county isn't restricted by zoning today. That said, the three towns inside the county, Huntsville (the county seat), Oneida, and Winfield, are their own governing bodies with their own mayors and boards of aldermen. If you're inside any of those town limits, different rules could apply, and I couldn't confirm what those are, so call the town directly before assuming county-level freedom carries over.

Dwellings, tiny homes, RVs, and building permits. I could not find an official Scott County page addressing tiny home standards, Appendix Q, or RV occupancy, nor a clear county building-permit office page. Tennessee lets counties opt in or out of parts of the state residential code, but whether Scott County has opted in wasn't confirmed from an official source. Don't guess here, call the county mayor's office and ask directly.

Septic and composting toilets. This one's clearer because it's state-run. Scott County is not one of Tennessee's "contract counties" (Blount, Davidson, Hamilton, Jefferson, Knox, Madison, Sevier, Shelby, Williamson) that operate their own septic programs. That means septic permitting in Scott County goes through the Tennessee Department of Environment and Conservation (TDEC) directly, under the state's subsurface sewage disposal rules. You'd apply through TDEC's statewide online portal. There's no dry-cabin exemption at the state level, and composting toilets still generally need NSF 41 certification and TDEC sign-off.

Greywater. No Scott County-specific rule found; falls back to the Tennessee plumbing code framework, which technically allows subsurface greywater irrigation but enforcement varies locally.

Rainwater harvesting. No restriction found at the county level, and Tennessee has no statewide restriction on collecting rainwater, so this looks fine.

Wells. No county-specific well ordinance found. Wells fall under Tennessee's statewide Water Well Act, requiring a licensed driller, administered by TDEC rather than any county water authority.

Utilities. No countywide mandatory-connection ordinance was found. Going off-grid for electricity looks unrestricted at the state and county level; any sewer/water hookup requirement would only kick in inside a municipality's service area, and I couldn't confirm those details for Huntsville, Oneida, or Winfield.

Bottom line: unincorporated Scott County looks pretty permissive on paper simply because so little has been formally regulated yet, but "not regulated" isn't the same as "confirmed safe," so verify anything important with the county mayor's office or TDEC before you build.
