37.2005, -87.1788 · 541 ft elevationRead this before you act on anything below. This is my researched starting point for Muhlenberg 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 rulesMuhlenberg County, KY
Zoning & raw-land occupancy
Unclear - verifyNo countywide zoning ordinance from the Muhlenberg County Fiscal Court was found; cities within the county like Central City and Greenville may have their own separate zoning rules to check with city hall. source
Dwellings, tiny homes & RVs
Unclear - verifyA commercial guide claims tiny homes are allowed under Appendix Q, but that's not an official source; the state DHBC lists the county under its jurisdiction but no county-specific tiny home or RV rule was confirmed.
Building permits & codes
Unclear - verifyKentucky's DHBC enforces the statewide building code and a state plumbing inspector covers the county, but whether a rural building permit is required outside city limits was not confirmed; ask DHBC or the county directly. source
Septic & composting toilets
Generally allowedThe Muhlenberg County Health Department requires a permit and soil evaluation for onsite sewage systems, with a minimum lot size of about three-quarters of an acre (32,670 sq ft); homeowners can self-install with a homeowner's permit. source
Greywater reuse
Generally allowedNo county-specific greywater page exists; greywater is governed by the state regulation 902 KAR 10:085, administered through the same county health department office that handles septic.
Rainwater harvesting
Generally allowedNo county or state restriction on non-potable rainwater collection was found; connecting collected rainwater to household plumbing would trigger the state plumbing code enforced locally by the state plumbing inspector.
Private wells & water rights
Generally allowedNo county-specific well permitting rule was found; the state baseline applies, meaning no state permit or fee for private well construction, but the driller must be Kentucky-certified.
Living disconnected from utilities
Unclear - verifyNo Muhlenberg County ordinance requiring hookup to grid power, public water, or sewer was found, but this is an absence-of-evidence finding rather than an official confirmation of off-grid legality.
