Off-Grid Living in Perry County, Tennessee

Perry County, Tennessee is one of those places where the honest answer to "what are the rules?" is: it depends who you ask, and there isn't much written down at the county level. I dug through what official sources exist, and I want to be upfront that Perry County doesn't have much of a standalone planning, zoning, or building-code web presence. That's not me being lazy, it's the actual state of the record.

Zoning: Tennessee counties only have zoning if they've voted to adopt it, under the state's county zoning enabling law (Title 13, Chapter 7, Part 1). I could not find an official Perry County zoning ordinance, map, or planning commission page. That suggests the county may have minimal or no formal zoning, but I can't confirm that from an official source, so treat it as unconfirmed and call the county mayor's office to ask directly.

Dwellings, tiny homes, RVs: No county-specific rule turned up. The state's default residential code framework (2018 IRC with the Appendix Q tiny-home provisions) is the only documented layer, and Tennessee lets counties opt out of the state's building code enforcement program.

Building permits: Tennessee runs a State Residential Building Code Enforcement Program that applies unless a county has opted out by a two-thirds vote of its legislative body, or has its own locally enforced code. I could not verify Perry County's current status on the state's list, so confirm with the Tennessee State Fire Marshal's Office residential permits program before assuming you don't need a permit.

Septic: This is the one area with a clear, confirmed local authority. The Perry County Health Department's Environmental Health division issues septic permits directly, and a permit is required for any home or shed not on city sewer, plus for replacing or adding to an existing system. This sits under Tennessee's statewide on-site sewage program (TDEC), administered locally by the health department. No county exemption for composting toilets was found, so the state's general expectations would apply.

Greywater, rainwater, wells: No Perry County-specific rules exist in what I found. Rainwater collection is unrestricted under Tennessee law. Wells fall under the state's licensed-driller requirement (Tennessee Water Well Act, administered by TDEC), with no added county layer confirmed. Greywater defaults to the state's generally permissive but loosely enforced baseline.

Utility disconnection: No county ordinance mandating hookup was found. Note that if you're inside Linden or Lobelville town limits, town rules could differ from the unincorporated county, so check with the specific town.

Bottom line: septic is locally regulated and enforced through the health department, everything else likely falls back to state default rules, but Perry County's thin online record means a phone call to the county and to Linden is genuinely the only way to be sure.
