Building permits, zoning and land rules in Butler County, Kentucky

Unincorporated Butler County does not require a building permit for a single-family dwelling; the county FAQ does not resolve plumbing, electrical, septic, floodplain or municipal approvals¹. Kentucky does not require single-family building inspections or certificates of occupancy unless a local ordinance requires them⁹. The Kentucky Residential Code still applies, and where no local single-family inspection program exists, mechanical-system and local electrical inspections remain separate¹⁰. Inside Morgantown, covered construction, excavation and alterations require a zoning administrator permit before work begins; septic permits remain with the Butler County Health Department^2,3.

Butler County's published process says no building permit is needed for a single-family dwelling, but it does not identify a county building office or dispose of the other approvals a project may need¹. The Butler County Health Department, at 104 North Warren Street in Morgantown, phone 270-526-3221, handles onsite sewage permitting and inspection^3,11. A private well requires no permit application or fee from the property owner; a Kentucky Certified Water Well Driller constructs it and files the state documentation⁸. A new driveway onto a state-maintained highway requires a written application to the Kentucky Department of Highways District Engineer¹².

We could not confirm whether zoning applies in unincorporated Butler County; ask Butler County Fiscal Court about the proposed use, setbacks, dwelling size and lot size before designing⁴. Within a Kentucky planning-unit jurisdiction, subdivision requires planning-commission approval before the plat can be recorded; ask Butler County Fiscal Court which planning authority, if any, covers a proposed lot split¹³. Agricultural zoning protection is conditional: road setbacks, floodplain structures, dwellings and specified conditional uses may still be regulated wherever zoning applies¹⁴.

Kentucky law requires an onsite sewage disposal permit from the local health department before construction, installation or alteration of a septic system, and in Butler County that means the Butler County Health Department^11,15. A licensed professional engineer can perform the site evaluation and design, but the final installation inspection must still come from the local health department¹⁶. Farmstead owners may obtain a septic permit and install a system on their own property; otherwise installation requires a Cabinet-certified installer¹⁵. Only about 7% of Butler County's soils carry no severe limitation for a conventional drainfield, so plan for a site evaluation and be ready for the health department's greywater or alternative-system framework if a conventional field won't work^7,17.

We could not confirm residential RV or tiny-home occupancy on an individual parcel in unincorporated Butler County; ask Butler County Fiscal Court before buying for that use⁴. In Morgantown, an RV cannot be the principal residential or commercial structure, permanent placement and occupancy are prohibited, and incidental or accessory use is limited to 14 days^5,6. Kentucky’s exclusion for event-related RV parking of up to 30 days does not authorize long-term residential occupancy¹⁸. Special-event camping in a regulated RV community requires notice to the local health department at least 20 days beforehand and is tied to an event lasting no more than 14 consecutive days per calendar year; that rule does not authorize camping on an individual private parcel¹⁹.

1. Call the Butler County Health Department at 270-526-3221 for a septic site evaluation before fixing the house location^11,15.
2. Confirm the parcel’s jurisdiction: Morgantown requires a zoning administrator permit for covered building work, while septic approval stays with the county health office^2,20.
3. Design a single-family home to the Kentucky Residential Code despite the county’s building-permit exemption^1,9.
4. Obtain a Division of Water floodplain permit before development within a floodplain or in, along or across a stream; consult the local floodplain coordinator about local approval, and check whether stream or wetland work requires Water Quality Certification^21,22.
5. Use a Kentucky Certified Water Well Driller for a new well⁸.
6. Apply in writing to the Department of Highways District Engineer before building a driveway onto a state-maintained road¹².

Kentucky excludes qualifying farm dwellings and buildings incident to farm operation and maintenance from its statutory definition of a building when they are outside municipal boundaries, are not used in retail trade, and are not a place of regular employment for 10 or more people²³. Buying farmland does not make every proposed building exempt: agritourism buildings generally must comply with the Kentucky Building Code, with limited seismic and architect-service exemptions for qualifying buildings built before December 31, 2016²⁴. Before closing, also arrange a septic site evaluation: only about 7% of Butler County soils have no severe limitation for a conventional drainfield^11,17.
