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

Yes. Henry County requires a building permit before a building, manufactured home or other structure covered by the zoning ordinance is erected, moved, enlarged or structurally altered¹. The permit comes from the zoning enforcement officer and, when applicable, the city or county building inspector¹. Limited exceptions cover recurring maintenance, low-value alterations, publicly owned utility work, approved subdivision improvements and very small structures¹. Kentucky has a mandatory residential building code, while permits, inspections and occupancy certificates for a single-family dwelling depend on a local requirement^1,9,10. Henry County supplies the local permit requirement, but we could not confirm whether it operates a single-family inspection program or requires a certificate of occupancy; ask Planning & Zoning which inspections and closeout documents apply^10,11.

Start with Henry County Planning & Zoning for the zoning and building-permit application¹. The application must include dimensional drawings showing the proposed structures, lot area, parking, water supply and sewage-disposal facilities, plus preliminary county health approval for the proposed water and sewage facilities¹. After zoning approval, the approved copy goes to the city or county building inspector when that review applies¹. Normal zoning-permit review is three days under ordinary circumstances¹. The Planning Commission establishes the fee schedule, keeps it posted at the zoning enforcement office and may impose a penalty fee when work begins before a required application is filed¹. Henry County's Planning & Zoning office administers zoning through a commission and Board of Adjustments representing incorporated cities and magisterial districts⁴. Septic permits are a separate step that stays with the North-Central District Health Department, in the cities as well as the unincorporated county³. Henry County Planning & Zoning is at 19 South Property Road and can be reached at 502-845-5707, ext. 2⁴. The North-Central District Health Department's main office is at 1020 Henry Clay St. in Shelbyville, phone 502-633-1243, and its on-site sewage program covers Henry, Shelby, Spencer and Trimble counties³.

Henry County has zoning administered through a county ordinance and map that also identify Eminence, New Castle, Campbellsburg, Pleasureville and Smithfield². Minimum lot area varies by district and by public-sewer availability; in the A-1 agricultural district it is 5 acres without public sewer, while A-2 and R-1 lots need 8,000 square feet with public sewer and 20,000 square feet without⁷. On A-1 tracts of 5 acres or more, garages and outbuildings need 15-foot side and rear setbacks¹. Municipal rules may also apply independently inside the incorporated cities⁴. Before buying, ask Planning & Zoning for the parcel's district and compare the intended dwelling, accessory structures and use with that district. Dividing land is regulated, and mobile-home subdivisions follow the same procedure as conventional-dwelling subdivisions¹². Kentucky's farmstead exemption is narrower than a blanket agricultural waiver: it applies to a qualifying farm dwelling and related farm buildings on at least 10 acres outside municipal limits when the property has bona fide agricultural or horticultural use and is registered with the county property valuation administrator⁶.

The North-Central District Health Department handles onsite sewage work for Henry County³. Local health department inspectors perform site evaluations and inspections, and a certified Kentucky onsite septic installer must install the system based on that evaluation⁵. A homeowner who wants to install the homeowner's own system must first obtain a homeowner permit through the local health department⁵. Only about 3.3% of Henry County soils are rated without severe limitations for a conventional septic drain field, so arrange the site evaluation before committing to a house location¹³. Kentucky prohibits seepage pits, cesspools and dry wells as onsite sewage systems except for narrow repair and legacy-lot exceptions¹⁴.

Henry County prohibits using a camper or recreational vehicle as a residential dwelling¹. Recreational-vehicle parks may be considered as conditional uses in specified districts, but that does not authorize residential use of an RV on an individual parcel¹. A manufactured home may be used as a dwelling under the zoning ordinance, but it must sit on a fixed permanent foundation with its wheels or mobile parts removed¹. A temporary manufactured home must have approved water, sewage disposal and appropriate utility connections when allowed by the Planning Commission's designated administrator². Henry County does not have a separately confirmed tiny-home rule or minimum dwelling floor area; ask Planning & Zoning how a proposed tiny home will be classified. Any tiny home treated as a building, manufactured home or other covered structure still needs the applicable zoning and building approval¹.

1. Ask Henry County Planning & Zoning for the parcel's zoning district and current fee schedule^1,4.
2. Confirm the district's lot and use controls before finalizing the site plan⁷.
3. Arrange the local health review because preliminary approval of water and sewage facilities must accompany the zoning application¹.
4. Submit dimensional drawings showing the structures, lot, parking, water supply and sewage disposal¹.
5. Take the approved zoning copy to the city or county building inspector when applicable, and confirm the required inspection and occupancy-certificate sequence^1,10,11.
6. Obtain the plumbing permit before work begins; an eligible homeowner may personally perform code-compliant plumbing for the homeowner's residence after applying and filing the required affidavit⁶.
7. If the site lies in an identified floodplain, obtain both state and local floodplain permits before development¹⁵.

Confirm zoning, legal access, buildable area, sewage feasibility and floodplain status before closing. Henry County's lot rules vary by district, and subdividing land is regulated^7,12. Septic feasibility deserves special attention because only about 3.3% of county soils are rated without severe limitations for a conventional drain field¹³. About 52.8% of the county's land has a slope of 15% or less, so parcel-level topography can materially change driveway and homesite costs¹³. Development in an identified floodplain requires both state and local permits¹⁵. Kentucky does not require a property owner to obtain a water-well permit or pay a well-permit fee, but a certified water-well driller must perform construction, modification or abandonment⁸. The county's effective property-tax rate is about 0.8%, with a median annual property-tax bill near $1,489¹³.
