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 rulesChester County, TN
Zoning & raw-land occupancy
Varies locallyZoning covers all of Chester County as of 2017, split between the County Building and Zoning Department (rural areas) and the City of Henderson's department (city and surrounding planning region). Which office you deal with depends on exactly where your parcel sits. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county-specific rule on tiny homes, Appendix Q, or RV occupancy was found; Tennessee lets counties decide this themselves, and Chester County's stance isn't published. Confirm directly with the Building and Zoning Department.
Building permits & codes
RestrictedThe county adopted the 2018 International Residential Code and actively enforces building permits countywide, updating codes periodically as directed by the state. source
Septic & composting toilets
RestrictedSeptic systems require a Septic System Construction Permit under state law via TDEC; no standalone Chester County environmental health office was found, so it's likely handled by a TDEC regional field office, but which one is not confirmed. source
Greywater reuse
Unclear - verifyNo Chester County ordinance or guidance on greywater reuse was found. State plumbing code technically allows it with restrictions, but local enforcement practice is not confirmed.
Rainwater harvesting
Generally allowedNo county-specific restriction was found, and Tennessee has no statewide restriction on rainwater collection, so this is presumed permitted.
Private wells & water rights
Unclear - verifyPrivate wells are governed statewide by the Tennessee Water Well Act requiring a licensed driller. No Chester County-specific well authority or overlay was confirmed.
Living disconnected from utilities
Unclear - verifyNo county ordinance requiring hookup to municipal water or sewer for off-grid properties was found. Henderson runs its own utility department for in-city service, but rural county parcels outside that service area aren't addressed in available materials. source
