Boyle County, KY
37.6476, -84.7728 · 991 ft elevationRead this before you act on anything below. This is my researched starting point for Boyle 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 rulesBoyle County, KY
Zoning & raw-land occupancy
Varies locallyBoyle County has countywide zoning run jointly with Danville, Junction City, and Perryville through the Boyle County Planning & Zoning Commission, under authority granted by Kentucky's KRS Chapter 100. This differs from many rural Kentucky counties with no zoning at all, so check your parcel's zone before assuming anything. source
Dwellings, tiny homes & RVs
Unclear - verifyNo official Boyle County page specifically addresses tiny homes or RV occupancy; since the county enforces building permits and the state residential code, a permanent dwelling likely needs a permit, but this is not confirmed for tiny homes/RVs specifically. Ask the Building Inspector's office directly.
Building permits & codes
Generally allowedBoyle County requires building permits and enforces the Kentucky Residential Code through its Office of the Building Inspector, the designated enforcement official for construction work in the county. source
Septic & composting toilets
Generally allowedSeptic systems are permitted and administered locally by the Boyle County Health Department's Environmental Services division, operating under state regulations (902 KAR 10:081, 10:085, 10:110, 10:140). Composting toilets aren't separately addressed, so treat them as needing health department review as an alternative system. source
Greywater reuse
Generally allowedNo Boyle County-specific greywater ordinance was found; this appears to inherit the state framework under 902 KAR 10:085, administered locally by the health department.
Rainwater harvesting
Generally allowedNo Boyle County ordinance restricting rainwater collection was found in official sources, so this appears to follow the state's generally permissive baseline.
Private wells & water rights
Generally allowedPrivate wells are permitted; Kentucky requires a certified well driller through the Kentucky Division of Water, and no Boyle County-specific well permit or fee was found. Most of the county is on public water systems already. source
Living disconnected from utilities
Unclear - verifyNo official Boyle County page explicitly requires or prohibits disconnecting from electric, water, or sewer utilities. That said, zoning, building code, and septic permit requirements still apply regardless of grid connection, so confirm with the Building Inspector and Planning & Zoning before assuming full off-grid status is unrestricted.
