Zoning, building permits and septic rules in Nicholasville, Kentucky

Nicholasville, Kentucky requires a building permit from the city's administrative official before any building is erected, moved or structurally altered1. The city runs its own zoning ordinance, administered by the planning director, not Jessamine County zoning2. Septic permits come from the Jessamine County Health Department, not the city3.

Do you need a building permit in Nicholasville, Kentucky?

Yes, for construction inside Nicholasville city limits. The city's zoning ordinance says no building or structure may be erected, moved, added to or structurally altered without a permit from the city's administrative official1. That rule is stricter than the state baseline: Kentucky's residential code does not require permits for a single-family dwelling unless a local ordinance does8, and Nicholasville's ordinance does.

Two conditions catch buyers. A permit application for a structure on a permanent foundation needs an engineered site plan from a licensed professional engineer or land surveyor, with an exception for open, unenclosed decks and porches1. And the city will not issue a building permit unless the builder holds the necessary Nicholasville occupational licenses9.

We could not confirm the city's building-permit fee schedule or whether it has an owner-builder exemption; ask the Planning Commission.

Who issues building permits in Nicholasville, and how do you reach them?

Inside Nicholasville, the city handles building permits, not the county. The city's Planning Commission page lists a contact for building and electrical permits at [email protected] and 859.885.938510. The city's zoning ordinance names the planning director as the official who administers and enforces it2.

The county's permit counter is for land outside city limits. Jessamine County's own residential building permit requirement covers the unincorporated portion of the county11, so a lot inside Nicholasville does not go through the county's application. For land outside the city, see the Jessamine County page.

Does Nicholasville have zoning, and what does it mean for mobile homes, lot size and setbacks?

Nicholasville has its own zoning ordinance, and the planning director administers it2. District rules decide what you can build, so find the parcel's district on the city's official zoning map first.

Mobile homes are allowed only in mobile home parks, and those parks are allowed only in the R-3 district and in residential planned unit developments; a park needs at least 2.5 acres4.

Examples by district:

  • A-1 agriculture: a 5-acre minimum lot, 200 feet of lot width, and setbacks of 50 feet front, 15 feet each side and 25 feet rear612.
  • R-1F single family: a 4,000-square-foot minimum lot, 40 feet wide (50 feet on corner lots)13. Homes need at least 800 square feet of living space at ground level and 1,200 square feet in total5. Buildings may cover at most 50 percent of the lot14.

We did not confirm lot rules for the city's other districts; the Planning Commission can give the schedule for a specific parcel.

How do septic permits work in Nicholasville?

Kentucky requires an on-site sewage disposal permit before anyone constructs, installs or alters a septic system15. In Jessamine County that permit comes from the local health department, and the first step is a site evaluation by a certified inspector16. The Jessamine County Health Department lists a $225 site evaluation and a $320 permit17.

We could not confirm which lots inside Nicholasville city limits are expected to use public sewer rather than septic, or whether the city requires sewer connection. Ask the Jessamine County Health Department and Nicholasville Utilities before assuming a septic system is an option on a city lot. Jessamine County's soils are a reason to ask: only 3% of the county's soils are rated not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system18.

Can you live in an RV or tiny home in Nicholasville?

We could not confirm a Nicholasville rule on living in an RV on private land, on temporary camping or on tiny homes; the city's zoning ordinance does not address them in any section we read. Ask the Planning Commission in writing before you buy or park anything. What is clear is that mobile homes are limited to mobile home parks4, so a placed manufactured home on an ordinary lot is not an option inside the city.

Utility hookups are tied to permits: no electric, gas, water or other utility service may be connected to a building in the city until the utility has confirmation of a valid building permit19. Anything you plan to live in and connect will need that permit first.

Building a home in Nicholasville: the steps, in order

  1. Find the parcel's zoning district on the city's official zoning map and read that district's lot, setback and size rules20.
  2. Ask the Jessamine County Health Department and Nicholasville Utilities whether the lot is served by public sewer or needs a septic site evaluation17.
  3. Have a licensed professional engineer or land surveyor prepare the site plan1.
  4. Make sure the builder holds the city's occupational licenses9.
  5. Apply for the building permit through the Planning Commission10.
  6. Arrange utility hookups only after the permit is confirmed19.

What stays with Jessamine County, and what to check before you buy in Nicholasville?

The city decides zoning and building permits within its limits2, but septic permits are a Jessamine County Health Department matter3. Driveways onto state roads need an encroachment permit21, and Kentucky requires development permits in identified floodplains22. Check the flood map for your parcel before you close.

Countywide numbers: Jessamine County's effective property tax rate is 0.8%7. Land outside the city follows the county's rules instead; see the Jessamine County page for those.

Watch-outs

  • Building permits inside Nicholasville come from the city, not Jessamine County, so a form downloaded from the county site is the wrong form for a city lot11.
  • Do not buy a lot for a mobile home without checking the zoning district: mobile homes are allowed only in mobile home parks in R-3 and planned unit developments4.
  • We could not confirm Nicholasville's building-permit fees, owner-builder rules, well rules or RV and tiny-home rules; call the Planning Commission at 859.885.9385 before you commit10.
