Off-Grid Living in Crockett County, Tennessee

Crockett County, out in West Tennessee, is a tough one to research because I could not find an official county government website with a published zoning ordinance, building code, or environmental health page. That's worth saying up front: a lot of what follows is the Tennessee state baseline filling in for gaps I couldn't confirm at the county level. If you're planning to go off-grid here, expect to make some phone calls before you buy land.

Zoning. Crockett County does have a Regional Planning Commission that doubles as the Board of Zoning Appeals, and its members are appointed by and serve at the pleasure of the County Mayor. That tells me the county has some zoning apparatus in place, but I could not locate an actual zoning map, district list, or ordinance text on an official site to say whether raw unincorporated land is zoned or effectively open. If your parcel sits inside Alamo, Bells, Friendship, or Maury City, zoning is handled by that town, not the county, so check with the municipality directly.

Dwellings, tiny homes, RVs. No county-specific page turned up on minimum square footage, tiny homes, or RV occupancy. Tennessee has adopted the IRC including Appendix Q (the tiny-home provision) as its state baseline, but whether Crockett County has opted in or out of enforcing the residential code at all is not confirmed.

Building permits. This is genuinely unclear. Plenty of rural West Tennessee counties don't run their own building permit program, but I couldn't verify Crockett County's status either way. Before you pour a foundation, call the County Mayor's office to find out whether a permit is even required locally.

Septic and composting toilets. This one is state-administered. Crockett is not listed among Tennessee's "contract counties" that run their own environmental health septic programs, which means septic permits here go through TDEC's Division of Water Resources and its regional Environmental Field Office rather than a county health department. Composting toilets fall under the same state standard, requiring NSF 41 certification, with no known dry-cabin exemption.

Greywater. No Crockett County or TDEC page specifically addresses greywater reuse in this county, so the state plumbing code baseline (subsurface irrigation or holding tank with a short storage limit) applies by default.

Rainwater harvesting. No county restriction found, so the generally unrestricted Tennessee state baseline applies. Collect away.

Wells. Private wells fall under Tennessee's Water Well Act, requiring a state-licensed driller. No separate Crockett County well ordinance turned up, so the state process is what governs.

Utility disconnection. Going off the electric grid is unrestricted statewide. Whether you can also disconnect from water or sewer if you're inside town limits would depend on Alamo, Bells, Friendship, or Maury City's own rules, none of which I found published online.

Bottom line: Crockett County's off-grid rules lean heavily on Tennessee's state defaults because the county's own paperwork isn't easy to find online. Get on the phone with the County Mayor's office and the Planning Commission before you commit to a plan.
