Henry County, Kentucky requires a building permit before a building, manufactured home or other structure covered by its zoning ordinance is erected, moved, enlarged or structurally altered1. Zoning applies countywide through one county ordinance that also covers Eminence, New Castle, Campbellsburg, Pleasureville and Smithfield, and living in a camper or recreational vehicle is prohibited23. Septic permits and inspections for every address come from the North-Central District Health Department, not the zoning office4.

Do you need a building permit 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 requirement121314. 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 apply1514.
Who issues building permits in Henry County, Kentucky?
Start with Henry County Planning & Zoning for the zoning and building-permit application16. 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 facilities16. After zoning approval, the approved copy goes to the city or county building inspector when that review applies16. Normal zoning-permit review is three days under ordinary circumstances16. 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 filed17. Henry County's Planning & Zoning office administers zoning through a commission and Board of Adjustments representing incorporated cities and magisterial districts5. Septic permits are a separate step that stays with the North-Central District Health Department, in the cities as well as the unincorporated county4. Henry County Planning & Zoning is at 19 South Property Road and can be reached at 502-845-5707, ext. 2.18 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 counties.19
Does Henry County, Kentucky have zoning?
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 without10. On A-1 tracts of 5 acres or more, garages and outbuildings need 15-foot side and rear setbacks20. Municipal rules may also apply independently inside the incorporated cities5. 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 subdivisions21. 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 administrator22.
How do septic permits work in Henry County, Kentucky?
The North-Central District Health Department handles onsite sewage work for Henry County4. Local health department inspectors perform site evaluations and inspections, and a certified Kentucky onsite septic installer must install the system based on that evaluation7. A homeowner who wants to install the homeowner's own system must first obtain a homeowner permit through the local health department6. 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 location23. Kentucky prohibits seepage pits, cesspools and dry wells as onsite sewage systems except for narrow repair and legacy-lot exceptions24.
Can you live in an RV or tiny home in Henry County, Kentucky?
Henry County prohibits using a camper or recreational vehicle as a residential dwelling3. 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 parcel3. 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 removed25. A temporary manufactured home must have approved water, sewage disposal and appropriate utility connections when allowed by the Planning Commission's designated administrator26. 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.
What are the steps to build a home in Henry County, Kentucky?
- Ask Henry County Planning & Zoning for the parcel's zoning district and current fee schedule517.
- Confirm the district's lot and use controls before finalizing the site plan10.
- Arrange the local health review because preliminary approval of water and sewage facilities must accompany the zoning application16.
- Submit dimensional drawings showing the structures, lot, parking, water supply and sewage disposal16.
- Take the approved zoning copy to the city or county building inspector when applicable, and confirm the required inspection and occupancy-certificate sequence161514.
- 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 affidavit9.
- If the site lies in an identified floodplain, obtain both state and local floodplain permits before development27.
What should you check before buying land in Henry County?
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 regulated1021. Septic feasibility deserves special attention because only about 3.3% of county soils are rated without severe limitations for a conventional drain field23. 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 costs28. Development in an identified floodplain requires both state and local permits27. 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 abandonment11. The county's effective property-tax rate is about 0.8%, with a median annual property-tax bill near $1,4892930.
Watch-outs
- Do not treat Kentucky's single-family permit default as the local answer: Henry County has a local permit requirement for covered construction131.
- Henry County permit fees can change because the Planning Commission establishes and may amend the posted schedule; obtain the current amount from Planning & Zoning before filing17.
- Residential use of a camper or RV is prohibited; temporary private-land camping, tiny-home treatment, accessory dwellings and minimum dwelling floor area remain unconfirmed, so ask Planning & Zoning about the exact proposal38.
