37.8007, -85.4342 · 682 ft elevationRead this before you act on anything below. This is my researched starting point for Nelson County, KY, 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 rulesNelson County, KY
Zoning & raw-land occupancy
RestrictedNelson County has adopted countywide zoning jointly with Bardstown, Bloomfield, Fairfield, and New Haven through the Joint City-County Planning Commission. Only listed uses are permitted per district, so raw-land occupancy is constrained by zoning district rules, not left open. source
Dwellings, tiny homes & RVs
RestrictedA Zoning Compliance Permit from the Planning Commission is required for dwellings, and manufactured homes need installer certification and HUD labeling. Whether tiny homes on wheels can be permanent residences isn't confirmed and should be checked with Planning & Zoning directly. source
Building permits & codes
RestrictedKentucky's statewide building code applies but is enforced locally by Nelson County Code Enforcement under the County Judge-Executive and Fiscal Court. Permit forms and fees are locally set and not available as fixed figures in official documents. source
Septic & composting toilets
Generally allowedSeptic systems are permitted but require an evaluation and permit from the Lincoln Trail District Health Department before a Zoning Compliance Permit is issued. Composting toilets aren't addressed in any official Nelson County document, so that determination would be site-specific through the health department. source
Greywater reuse
Unclear - verifyNo Nelson County or Lincoln Trail District specific greywater rule was found; this likely falls under Kentucky's general state framework but is not confirmed locally. Contact the Lincoln Trail District Health Department Environmental office for a direct answer.
Rainwater harvesting
Unclear - verifyNo Nelson County ordinance or health department page addressing rainwater harvesting was found in official sources, so this is not confirmed and presumably inherits the state baseline with no dedicated permit scheme.
Private wells & water rights
Generally allowedPrivate wells are permitted, with testing and support available through the Lincoln Trail District Health Department. No Nelson-specific well permit fee or ordinance was found beyond the state's certified driller requirement.
Living disconnected from utilities
Unclear - verifyNo Nelson County ordinance explicitly requires connection to grid power or municipal water and sewer, but active zoning and building enforcement still apply. Whether a home can be legally occupied with zero utility connections is not confirmed and should be asked of Code Enforcement directly.
