Read this before you act on anything below. This is my researched starting point for Crockett County, TN, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesCrockett County, TN

Zoning & raw-land occupancy

Varies locallyCrockett County has a Regional Planning Commission that also acts as the Board of Zoning Appeals, appointed by the County Mayor, so some zoning apparatus exists. But no official zoning map, district text, or ordinance could be found, and towns like Alamo, Bells, Friendship, and Maury City control zoning within their own limits. source

Dwellings, tiny homes & RVs

Unclear - verifyNo county page addresses tiny homes, minimum size, or RV occupancy; Tennessee's adoption of the IRC with Appendix Q is the presumed state baseline, but the county's opt-in/opt-out status is not confirmed.

Building permits & codes

Unclear - verifyNo Crockett County building department website was found, and it's not confirmed whether the county enforces the state residential building code at all. Call the County Mayor's office to find out. source

Septic & composting toilets

RestrictedTennessee's septic permitting is a state program administered by TDEC's Division of Water Resources; Crockett County is not one of the independent 'contract counties,' so permits go through TDEC's regional Environmental Field Office rather than a county health department. source

Greywater reuse

Unclear - verifyNo Crockett County or TDEC page specifically covers greywater here, so the general state plumbing code baseline (subsurface irrigation or holding tank) is assumed to apply.

Rainwater harvesting

Generally allowedNo county ordinance restricting rainwater collection was found, so Tennessee's generally unrestricted state baseline applies.

Private wells & water rights

Generally allowedPrivate wells are regulated under Tennessee's state Water Well Act and require a state-licensed driller; no separate Crockett County well ordinance was found. source

Living disconnected from utilities

Varies locallyDisconnecting from the electric grid is unrestricted statewide. Water or sewer disconnection rules, if any, would depend on whether the property is inside Alamo, Bells, Friendship, or Maury City, and no official ordinance on this was found.
