Boone County's Planning Commission, in the County Administration Building at 2950 Washington Street in Burlington, administers planning, zoning and building services for the Northern Kentucky county that runs from the Ohio River south and west of the Cincinnati suburbs. Its defining feature is the Cincinnati/Northern Kentucky International Airport and the air cargo operation around it, which has drawn warehousing, logistics and light industrial development at a scale unusual for a county this size.
The Kentucky Building Code and Kentucky Residential Code apply here without local amendment, as everywhere in the Commonwealth, so what Boone County controls is its zoning, its subdivision regulations, its fee schedule and its inspection programme. The cities within the county — Florence, Union, Walton and the others — each hold their own zoning ordinances, and Florence at around thirty-four thousand residents is the largest, well below the threshold at which a city would carry a programme of this scale on its own.
This guide covers Boone County, including Florence, Union, Walton, Burlington and Hebron. Kenton County to the east runs its services through a joint agency, and Grant, Gallatin and Carroll counties to the south run their own arrangements.
The airport shapes the development market. Boone County holds the Cincinnati/Northern Kentucky International Airport and the air freight operation built around it, which has made warehousing, logistics and light industrial construction the dominant commercial work in a county of a hundred and forty thousand. Height, noise and approach-surface questions reach a great deal of the land around Hebron, and they arrive before the building code does.
What requires a building permit in Boone County?
Kentucky runs a mini/maxi code, and the phrase carries real weight. The Kentucky Building Code at 815 KAR 7:120 and the Kentucky Residential Code at 815 KAR 7:125 are statewide, uniform and mandatory, and no local government may adopt or enforce any other building code — the code is both the minimum and the maximum. The Department of Housing, Buildings and Construction adopts them; Boone County enforces them. The current editions are the 2018 Kentucky Building Code, Fourth Edition and the 2018 Kentucky Residential Code, Third Edition, both built on the 2015 International Codes with Kentucky amendments that supersede any conflicting model provision. Detached one- and two-family dwellings and townhouses fall under the residential code; everything else under the building code. What is local in Boone County is the inspection programme, the fee schedule, zoning and planning, contractor registration, and the county's zoning and the airport's development context.
The codes draw the exemption line and it is the same line across the Commonwealth. Ordinary repairs need no permit; constructing, altering, repairing, moving, demolishing or changing the occupancy of a building does. Electrical, plumbing and heating and air work carry their own permits and their own state licences, and Boone County's zoning and planning approvals sit outside the building code entirely — a municipality may not add building requirements, but it may and does regulate use, setbacks and site development.
Typically permit required
- Any construction, alteration, repair, demolition or change of occupancy under the Kentucky Building Code or Residential Code
- Zoning and subdivision approval under the ordinance of the city or county area where the site sits
- Electrical, plumbing and heating and air work, each by a state-licensed contractor on its own permit
- New buildings, additions and any structural work on an existing building
- Alterations, repairs and renovations under the building or residential code, and any change of occupancy
- Decks, accessory structures above the code threshold, retaining walls and swimming pools
Often exempt
- Ordinary repairs that do not alter structure, egress or systems
- Ordinary repairs that do not alter structure, egress or systems
- Painting, papering, flooring, cabinets and similar finish work
- Like-for-like replacement that the codes place below the permit threshold
- Small accessory structures below the code's threshold — the zoning ordinance still applies
What is actually local, and what is not
The code is the Commonwealth's and cannot be added to. Boone County's layer is its building inspection programme and the certified inspectors staffing it, the fee schedule its ordinance sets, the zoning ordinance and planning commission that govern use and site development, any local contractor registration it requires, and the airport's approach surfaces and the industrial development around it, and the individual cities' zoning ordinances.
Who handles permitting in Boone County?
The Boone County Planning Commission administers planning, zoning and building services, with certified inspectors as the state regulation requires of a local inspection programme. The county fiscal court and the individual city councils adopt the zoning ordinances, the airport board's approach and height requirements reach the land around Hebron, and the state Department of Housing, Buildings and Construction retains its role on certain commercial projects and licenses the trades.

Permit types
Residential permits
A Boone County house project files with the planning commission against the Kentucky Residential Code and the zoning ordinance of the city or county area where the site sits, with the electrical, plumbing and heating and air work carried out by state-licensed contractors on their own permits. Kentucky issues no statewide general contractor licence, so any local registration requirement is the county's or the city's own.
How Kentucky contractor credentials work
Kentucky issues no statewide general contractor licence. The Department of Housing, Buildings and Construction licenses the specialty trades — electrical contractors and electricians, plumbing contractors and plumbers, heating and air conditioning contractors, along with boiler, fire sprinkler and fire alarm contractors and the building inspectors themselves — and those licences are valid across the Commonwealth. General contracting is regulated locally instead: a city or county may require its own contractor licence or registration, and one jurisdiction's licence does not carry into the next. Boone County's own requirement, if it has one, is the credential to confirm before a permit is pulled, alongside the state trade licences the department verifies at the counter.
Commercial permits
Commercial and industrial work in Boone County is dominated by the airport corridor — warehousing, air freight facilities and light industry around Hebron and along the interstate — where approach surfaces, height limits and noise contours are settled alongside zoning before the building permit. The state department retains its role on certain commercial projects, elevators and boilers.
Plan review, local programmes and the state's role
Kentucky splits plan review between the state and the locality. The Department of Housing, Buildings and Construction's Division of Building Code Enforcement reviews plans and inspects new construction, additions, alterations and changes of occupancy for buildings under the Kentucky Building Code, unless the local government operates a certified programme holding that authority itself — and a local government running an inspection programme must provide at least one Kentucky Certified Building Inspector and at least one certified electrical inspector, reporting them to the department. Zoning approval, planning commission review and site development sit with Boone County and run ahead of the permit. In Boone County the airport's approach surfaces and noise contours govern height and use across a wide area, the Ohio River frontage brings floodplain review into the file, and each city's own zoning ordinance decides use and setbacks. Fees a local government charges are required by statute to cover the cost of the service performed and not to exceed it.
Boone County permit costs and fees
Fees follow the county's schedule, which by statute may not exceed the cost of the service performed, with the trades permitted separately under the state licences.
| Item | Fee or rule |
|---|---|
| Building permit | The county's fee schedule, by project type and construction value |
| Zoning and subdivision | Under the ordinance of the city or county area in which the site sits |
| Trade permits | Electrical, plumbing and heating and air by state-licensed contractors |
| Airport review | Approach surface and height review where the site falls within it |
| Statutory limit | Local fees may not exceed the cost of the service performed |
| State fees | Department fees where it reviews the project |
Florence would not reach the floor alone. Boone County has around a hundred and forty thousand residents; Florence, its largest city, has about thirty-four thousand. As in Kenton County next door, the county rather than any of its cities is the jurisdiction operating at scale — which is why Northern Kentucky permitting is a county question first and a city question second.
Trade permits and who may pull them
The trades are permitted separately from the building permit and carried out by contractors holding the state licences the Department of Housing, Buildings and Construction issues.
Permit required
- Sites near the airport — approach surface, height and noise review alongside zoning
- Electrical — state-licensed electrical contractor; separate permit and a certified electrical inspector
- Plumbing — state-licensed master plumber or plumbing contractor; separate permit, inspected under the state plumbing code
- Heating and air conditioning — state-licensed HVAC contractor; separate mechanical permit
- Fire sprinkler and fire alarm — state-licensed contractor, with State Fire Marshal review where it applies
Typically exempt
- Like-for-like replacement the trade codes place below the permit threshold
- Work a homeowner may perform on their own residence where the local programme allows it
How to apply for a Boone County building permit
Zoning approval, and planning commission or site development review where the ordinance requires it, precede the building permit.
Commercial plan review sits with the state department unless the local programme holds that authority; residential is local.
The state licenses the trades; general contractor registration, where it exists, is the city's or county's own.
Reviewed against the Kentucky Building Code or Kentucky Residential Code as adopted, with no local amendments to satisfy.
Fees are set by local ordinance and by statute may not exceed the cost of the service performed.
Footing to final, with the trades inspected on their own permits, then the certificate of occupancy.
Review, corrections and what actually causes delay
Boone County reviews through the planning commission, in a county carrying industrial development volume out of proportion to its population. What delays a file here is an airport approach or height question raised after design, and a zoning answer taken from the wrong city's ordinance.
Inspections in Boone County
Inspections follow the codes' sequence — footing, foundation, framing, rough trades, insulation and final — and are requested from the local inspection programme by permit number, with the electrical inspections carried by a certified electrical inspector. Work that passes final receives a certificate of occupancy for new buildings and changes of occupancy. Boone County inspects in the codes' sequence through its building department, with electrical inspections carried by a certified electrical inspector as the state regulation requires, and the certificate of occupancy following the finals.
