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 rulesButler County, KY
Zoning & raw-land occupancy
Unclear - verifyKentucky's KRS Chapter 100 lets counties opt into planning and zoning, but no official Butler County zoning map, ordinance, or planning commission page could be found. Whether the county has adopted zoning at all is not confirmed; ask the Judge-Executive's office. source
Dwellings, tiny homes & RVs
Unclear - verifyKentucky's KRS 198B sets a uniform statewide residential code enforced locally or, absent a local building department, by the state DHBC. It's not confirmed whether Butler County or Morgantown has its own building department that would review tiny homes or RVs as dwellings.
Building permits & codes
Varies locallyThe Kentucky Residential Code is the mandatory statewide code for one- and two-family homes, per the state Department of Housing, Buildings and Construction (DHBC). Enforcement is local if a building department exists, otherwise it falls to DHBC; no county-specific building department page was confirmed for Butler County. source
Septic & composting toilets
Generally allowedSeptic systems are governed statewide by Kentucky Administrative Regulations (902 KAR Chapter 10), with permitting and inspections delegated to local health departments. In Butler County, the Butler County Health Department (part of the Barren River District Health Department) administers this. source
Greywater reuse
Varies locallyNo Butler County-specific greywater ordinance was found; greywater is presumed to fall under the same state regulation (902 KAR 10) used for septic, administered by the Butler County Health Department, but this isn't separately confirmed. source
Rainwater harvesting
Unclear - verifyNo Butler County ordinance or health department guidance on rainwater harvesting was found in official sources; not confirmed either way.
Private wells & water rights
Unclear - verifyNo Butler County-specific well permitting page was found. State-level Kentucky Certified Water Well Driller standards are presumed to apply without added local requirements, but this is not confirmed for Butler County.
Living disconnected from utilities
Unclear - verifyNo Butler County ordinance requiring grid power, municipal water, or sewer hookup was found. Whether local building or occupancy rules (if any exist) would indirectly require utility connections is not confirmed.
