Clark County, Kentucky Building Permit Guide

Clark County has a local building inspector, and the state’s contact sheet for the county, updated October 27, 2026, says that inspector’s coverage “includes City of Winchester,” the county’s only city. The sheet lists only individual contact details, so ask the county judge/executive’s office or the City of Winchester how to reach the program, which buildings it permits and its fees. The state Division of Building Code Enforcement (502-573-0373) keeps plan review of the larger buildings, HVAC and plumbing permits are state permits, and the Clark County Health Department evaluates septic sites for $200.

What requires a building permit in Clark County?

Because Clark County has a local inspection program, the work is split the way Kentucky’s building code splits it everywhere a local program exists. The local building department handles the buildings section 104.15 assigns to it; the state’s Division of Building Code Enforcement keeps plan review and inspection of the section 104.16 buildings, which the state describes as those for more than 100 people, over three stories or 20,000 square feet, and every school, hospital, care home, high-hazard and state-owned building. Single-family homes are reviewed and inspected locally where a single-family program exists.

The state sheet confirms the program’s territory but not its scope by building type. If it turns out the local program does not cover single-family homes, the state’s rule for houses applies instead: the Kentucky Residential Code must still be met, and only the mechanical system (by the state HVAC division) and the wiring (by the local county electrical inspector) are inspected, along with permitted plumbing.

What the county decides and what the state holds

Subdivision is a joint city-county matter: Winchester Municipal Utilities’ developer manual (revised May 2021) sends developers through the Winchester-Clark County Subdivision Regulations, with preliminary and final plats approved by the Winchester-Clark County Planning and Zoning Commission and recorded with the Clark County Clerk. The county also shares the local building inspector with Winchester, routes electrical inspection through the judge/executive’s office, and is in the flood insurance program. The state keeps its share of plan review, every HVAC and plumbing permit, manufactured housing, modular approvals, elevators, boilers and trade licensing.

Clark County building department: who handles permitting

The Clark County contact sheet lists the local building inspector (coverage including Winchester) and the state building, manufactured housing, electrical, elevator, HVAC, plumbing and boiler inspectors, each with individual contact details. The table gives the offices to start with.

Clark County permit types and supporting documents

Expect two tracks for most Clark County jobs: the local permit from the shared inspector, and state permits in SmartGov, the state’s system for building plan review, HVAC, manufactured housing, plumbing and fire prevention filings. SmartGov asks whether a project is under local, expanded or state jurisdiction before it accepts an application.

Residential permits

Ask the local inspector first whether a house, addition or accessory building needs a local permit. The state trade permits apply in any case: an HVAC permit, sold only to licensed or authorized applicants, and a plumbing permit, which a licensed master plumber or an owner-occupant may buy. An owner who plumbs their own home, or a home they are building to live in, applies before starting, files an affidavit, does the work personally under the state plumbing code and can hold one new-home homeowner permit per five years. A rural lot also needs the health department’s septic approval, described below.

Commercial permits

Buildings in the state’s share are filed with the Division of Building Code Enforcement with complete construction documents and cannot start until approved. Smaller commercial buildings go to the local inspector. Modular buildings of any size or use need state site placement approval, and elevators and boilers separate state permits. A development that extends water or sewer lines also goes through WMU’s engineering review, below.

For tenant improvements and new commercial builds, Alliance handles commercial permit filing through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Septic. Every individual sewage system in Clark County is permitted through the health department. An environmentalist evaluates the lot and sets the system’s location, design, type and size; alternatives such as constructed wetlands are allowed. Applications are taken in person at 273 Shoppers Drive, and the evaluation fee is $200.
• Subdivision. Lot splits and new subdivisions follow the Winchester-Clark County Subdivision Regulations, with plats approved by the planning commission and recorded with the County Clerk.
• Water and sewer extensions. WMU’s Engineering Department reviews engineer-signed plans (its policy allows up to 30 days), the WMU Commission approves them before they go to the state environmental agency, and the Winchester or Clark County fire department checks hydrant locations.
• Floodplain. Both the county and Winchester participate in the flood insurance program on a map effective February 28, 2025; ask about floodplain review for a mapped lot.
• State highways. A Kentucky Transportation Cabinet encroachment permit from District 7 in Lexington.

Clark County permit costs and fees

The published sources give no local building permit fee schedule for Clark County or Winchester; ask the local inspection program before budgeting. Published official fees are:

Worked example. A rural house with 20 plumbing openings pays the $200 septic evaluation and a $50 + (20 × $14) = $330 state plumbing permit, $530 in published fees before the local building permit, the HVAC permit and electrical fees. WMU’s system development charges, printed in its developer manual (revised May 2021), apply to water and sewer line extensions in the WMU, East Clark County Water District and Boonesborough Water Association service areas and are collected when connection fees are paid; the manual does not list tap fees, so ask WMU at 859-744-5434 for current tap fees and to confirm the charges.

Trade permits and who may pull them

• Electrical. The state portal does not sell electrical permits for private property. The Clark County sheet sends applicants to the county judge/executive’s office, or to the city office for work in Winchester, for the local electrical inspection; a state electrical inspector is also assigned to the county.
• HVAC. Neither Clark County nor Winchester is a local HVAC jurisdiction on the state’s list (updated May 13, 2025), so new construction takes a state HVAC permit and a state HVAC inspection.
• Plumbing. State permits cover new plumbing, a moved fixture, a new or replacement house sewer, water service or water heater, and an added backflow preventer. The plumbing inspector’s desk is at the health department’s Professional Avenue office on Friday mornings from 8:00 to 9:30 Eastern. Farm dwellings and farm buildings on 10 acres or more outside Winchester’s limits, in bona fide agricultural use and registered with the county PVA, may qualify for the farmstead exemption.
• Licenses. Electricians, plumbers and HVAC contractors are licensed by the state. A homeowner may do the electrical and heating and air work on their own home without the trade license, with a permit. The published sources show no local contractor license or registration.

How to apply for permits in Clark County

Review, corrections and what causes delay

Utility and plat approvals can take longer than the building permit: WMU allows itself up to 30 days to review extension plans, then needs Commission approval before the state environmental review can begin, and a final plat must be recorded first. For buildings in the state’s share, plan approval must come before construction. Septic suitability can also change a rural plan, so get the site evaluation early.

Clark County inspections and final approval

The local building inspector inspects the projects it permits in the county and in Winchester; ask which stages it requires and whether it issues a certificate of occupancy. State-reviewed buildings are inspected by the state building inspector for Clark County. The state HVAC and plumbing inspectors inspect their permits, the local electrical inspector the wiring, and the health department the septic system it approved. WMU inspects water and sewer extensions that will become part of its system, at the developer’s cost.

Kentucky building code in Clark County

FEMA’s Community Status Book lists both Clark County and the City of Winchester as participating communities in the National Flood Insurance Program, each with a current effective flood map dated February 28, 2025. Check that map before buying or building on a low-lying lot.

Kentucky has one mandatory statewide building code that local governments may not add to. Cities and counties enforce it and run zoning. The state reviews plans for larger and higher-risk buildings, and the local program reviews smaller ones. Kentucky rules
