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

Yes. Henderson County requires a building permit before excavation, construction, moving or exterior alteration of a building, including an accessory building¹. Routine maintenance, interior alterations and exterior work that does not appreciably enlarge exterior dimensions—such as siding, windows, doors and roofing—are excepted¹. The Henderson County Codes Department issues building permits and enforces building codes and zoning ordinances⁹.

A permit application must include a scaled plan showing the lot, structure and yards, plus approval of proposed water and sewer facilities from the State Plumbing Inspector¹. The enforcement officer must conduct a final inspection after notice that the property is ready for occupancy or use, and covered land or buildings cannot be used until a certificate of occupancy confirms compliance¹. County permit fees are published, and plumbing construction or alteration requires a separate plumbing permit before work begins^2,11.

Start with the Henderson County Codes Department at 1990 Barrett Court, Suite H, Henderson, Kentucky, or call 270-827-6030⁹. The department issues county building permits and enforces building codes, property maintenance codes and zoning ordinances⁹. Ask Codes for the application, current fee schedule and inspections for the proposed work; the county publishes permit fees, and the ordinance requires a final inspection tied to the certificate of occupancy^1,2.

The enforcement officer must act on a complete application within two weeks or explain the delay to Fiscal Court, and a permit becomes void after six months without substantial progress¹. For zoning and land-use questions, contact the Henderson City-County Planning Commission at 1990 Barrett Court, Suite C, Henderson, Kentucky, or call 270-831-1289⁵. The county offers owner-builder exemption forms, but the forms' eligibility and legal effect should be confirmed with Codes before relying on them^8,9.

Yes. Henderson County's zoning ordinance divides the county into districts, while incorporated municipalities may have separate zoning ordinances^3,5. The parcel's jurisdiction and mapped district determine allowed uses, setbacks, building height, lot coverage and other dimensional standards^1,5,12.

Minimum lot size varies by district, dwelling type and utility arrangement¹. New single-family lots served by community water and individual septic must have at least three-quarters of an acre¹. Dividing land for eventual residential, commercial or industrial lots also triggers subdivision regulations in addition to zoning¹. Agricultural land receives a conditional zoning exemption, but street and highway setbacks and floodplain controls may still apply, and dwellings—including manufactured homes—still require permits and certificates of occupancy¹. Henderson County's general minimum dwelling size, tiny-home rule, accessory-dwelling rule and long-term RV rule could not be confirmed; ask Planning Commission staff about the parcel⁵.

Green River District Health Department administers Henderson County's onsite sewage permits through the local health department⁴. Start with the Henderson County Health Center at 472 Klutey Park Plaza, Henderson, Kentucky, or call (270) 826-3951 for routing to the environmentalist¹³. A site evaluation and permit are required before an onsite system is constructed, installed or altered, and inspection is required before backfilling⁷.

Only about 12.5% of mapped county soils are rated without severe limitations for a conventional septic drain field, so make site approval an early purchase contingency¹⁴. County zoning requires connection where sewer mains are accessible; otherwise, individual water and sewage facilities must meet State Plumbing Inspector requirements¹. Lots using an individual well and septic system must also satisfy Green River District Health Department rules and the applicable district and lot-size standards¹. Kentucky prohibits seepage pits, cesspools and dry wells except for narrow regulatory exceptions, so an improvised waste system is not an alternative to approval¹⁵.

We could not confirm a Henderson County rule allowing long-term RV occupancy on private land, so ask the Henderson City-County Planning Commission whether the parcel's district permits an RV for temporary or residential use⁵. Kentucky's allowance for sleeping in a lawfully parked vehicle on a public road, street or parking lot for less than 12 hours does not authorize long-term RV living on private land¹⁶.

Henderson County's specific tiny-home occupancy rule and a general minimum dwelling size also could not be confirmed; a dwelling still requires zoning and permit review under the applicable building-code framework^1,5,17. Manufactured homes are expressly treated as conditional uses in agricultural areas and the RR district, and they require applicable lot, septic, building-permit and certificate-of-occupancy approvals¹. If sewer is unavailable, an approved private sewage system is required; seepage pits, cesspools and dry wells are generally prohibited^15,18.

1. Ask the Henderson City-County Planning Commission to identify the governing jurisdiction, zoning district, allowed use, setbacks, height, lot coverage and lot-size standard^1,3,5,12.
2. If creating a new lot, obtain planning-commission subdivision approval before recording the plat^1,19.
3. Where public sewer is unavailable, obtain the health department's site evaluation and septic permit before installation^4,7.
4. Submit the scaled site plan and water-and-sewer approval with the building-permit application to Codes^1,9.
5. Resolve driveway access to a public road and obtain the state-highway application when applicable^3,20.
6. Obtain state and local permits before development in an identified floodplain^21,22,23.
7. Schedule required septic and building inspections, then obtain the certificate of occupancy before use^1,7.

Confirm the parcel's jurisdiction, zoning district, permitted use, setbacks, height, lot coverage and lot-size standard with the Henderson City-County Planning Commission before closing^1,3,5,12. Make septic feasibility an early contingency because only about 12.5% of mapped soils lack severe limitations for a conventional drain field¹⁴. Check the proposed house, driveway and septic areas against flood maps; identified floodplain development requires state and local permits^21,22,23.

The county reviews driveway access to public roads under its access standards, while access onto a state highway requires an application to the Department of Highways district engineer^3,20. A private well does not require an owner-applied Kentucky construction permit, but a Kentucky-certified well driller must perform and document the work²⁴. If rental income matters, Henderson County requires a Conditional Use Permit before a short-term rental is operated or advertised¹. The effective property-tax rate is about 0.9%, and the median annual property-tax bill is about $1,455¹⁴.
