Off-Grid Living in White County, Tennessee

If you're eyeing raw land in White County, Tennessee for an off-grid setup, here's what I found digging through official sources, and where the trail runs cold.

Zoning. White County doesn't appear to run a comprehensive land-use zoning code out of the county government itself. What I could confirm is a Planning Commission whose job, per the county's own site, is mostly subdivision review and advising on additions to the county road list. There's a separate zoning ordinance document floating around on a third-party planning archive site, but I couldn't verify its current authoritative scope from an official county page, so I'm calling this "varies" until you confirm with the Planning Commission directly whether raw, non-subdivided land is subject to any use restrictions.

Dwellings, tiny homes, RVs. I found nothing county-specific here. The Building Inspector's page references the 2018 International Residential Code generally, but doesn't call out Appendix Q (the tiny-home provisions) or RV occupancy rules. That means you're likely falling back on state baseline and whatever the inspector decides at the counter, so ask directly before you build small or live in an RV long-term.

Building permits. This one's clear: White County enforces building codes in unincorporated areas, it hasn't opted out like some rural Tennessee counties do. The Building Inspector's office handles building, plumbing, and mechanical permits, and you can apply online. The county has a 2018 IRC code book on file with the County Clerk, confirming that's the enforced standard.

Septic and composting toilets. This is the biggest open question in my research. Statewide, septic permitting in Tennessee runs through either a county environmental health office (contracted) or directly through TDEC's Division of Water Resources field offices, depending on the county. I could not find an official White County environmental health page telling me which model applies here. Some neighboring counties (like Greene) have moved to direct TDEC online applications. Call TDEC's regional water resources contact or the county to find out which path applies to you before you plan a septic system or composting toilet.

Greywater. No White County-specific ordinance found. This defaults to Tennessee's state plumbing code, which I can't call permissive or restrictive with confidence at the county level.

Rainwater harvesting. No county restriction found. Tennessee is generally permissive on rainwater collection statewide, so I'd call this permitted, but always worth a quick confirmation call if you're building anything substantial like a cistern system.

Wells. No county-specific well ordinance found. Wells fall under Tennessee's statewide Water Well Act, which requires a licensed driller. No local water authority page on this was located.

Utilities. No mandate to hook up to grid power, water, or sewer was found at the county level. This inherits the state baseline, which generally doesn't force electric disconnection concerns, but water/sewer mandates can depend on availability and any local requirement I wasn't able to confirm.

Bottom line: White County has real teeth on building permits, is murky on septic authority, and is largely silent (which usually means state-default) on tiny homes, greywater, rainwater, and utility disconnection. Call before you build.
