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 rulesHart County, KY
Zoning & raw-land occupancy
Varies locallyHart County has no countywide zoning ordinance; unincorporated land use is unregulated by zoning. Zoning exists only inside Munfordville, Horse Cave, and Bonnieville city limits, each with its own ordinance. source
Dwellings, tiny homes & RVs
Unclear - verifyNo official Hart County document specifies tiny-house or RV occupancy standards outside mobile home parks; only mobile-home-park lots have documented standards. Ask the Hart County Planning Commission or the relevant city hall for anything more specific. source
Building permits & codes
Varies locallyHart County's building information sheet says an electrical permit is required only if connecting to city utilities, following the state's local-option enforcement scheme under KRS 198B.060; no standalone county building code was found. source
Septic & composting toilets
Generally allowedSeptic systems are permitted and regulated through Kentucky's statewide Onsite Sewage Disposal Systems Program, administered locally by the area health department, which handles site evaluation and inspection. source
Greywater reuse
Generally allowedGreywater reuse is permitted under Kentucky's statewide rule (902 KAR 10:085); no Hart County-specific ordinance or restriction was found.
Rainwater harvesting
Generally allowedNo Hart County or municipal rule restricting rainwater harvesting was found in official sources reviewed; this appears to default to the permissive state baseline.
Private wells & water rights
Generally allowedPrivate wells are permitted statewide, but Kentucky law requires a state-certified well driller for construction, alteration, or repair; no separate Hart County well permit was found. source
Living disconnected from utilities
Unclear - verifyNo Hart County ordinance mandating grid power, public water, or sewer hookup was found. The only documented rule is that an electrical permit is required if you choose to connect to city utilities, which is conditional rather than mandatory. source
