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 rulesBoone County, KY
Zoning & raw-land occupancy
RestrictedBoone County has countywide zoning administered jointly with Florence, Union, and Walton by the Boone County Planning Commission, unlike many unzoned Kentucky counties. Land use and lot occupancy depend on the zoning district. source
Dwellings, tiny homes & RVs
Varies locallyPermanent dwellings are regulated under zoning and building codes; RVs are treated differently, at least for short-term rentals. Tiny home/THOW rules as primary residences were not confirmed, so check directly with Planning & Zoning. source
Building permits & codes
RestrictedBoone County has adopted the Kentucky Building and Residential Codes by ordinance and requires a permit from the County Building Inspector's Office before any residential construction begins. source
Septic & composting toilets
Generally allowedSeptic systems are permitted through the Northern Kentucky Health Department, which evaluates the site and issues permits under Kentucky's state onsite sewage rules (902 KAR Chapter 10). Composting toilets as alternatives are not separately addressed on Boone-specific pages. source
Greywater reuse
Unclear - verifyNo Boone County-specific greywater ordinance was found; the state framework under 902 KAR 10:085 likely applies by default. Confirm with the Northern Kentucky Health Department or the state Cabinet for Health and Family Services.
Rainwater harvesting
Generally allowedNo Boone County ordinance restricting rainwater harvesting was found, so the state's generally permissive stance on non-potable collection appears to apply.
Private wells & water rights
Generally allowedNo Boone County-specific well ordinance was confirmed; Kentucky's certified-well-driller requirement is the operative rule, and well approval is likely part of the county's building permit site review process.
Living disconnected from utilities
Unclear - verifyNo explicit ordinance requires connection to grid power or municipal water/sewer, but mandatory building permits and septic/water approvals practically constrain full off-grid disconnection. source
