The Unified Government of Wyandotte County and Kansas City, Kansas permits construction through its Building Inspection division at the Neighborhood Resource Center, 4953 State Avenue, Kansas City, KS 66102 (913-573-8620, Monday to Friday 8:00 am to 5:00 pm). Staff currently work remotely and in-person submissions are not being received, so applications go through the NRC E-Link (Accela Citizen Access) portal. The city and the county merged, so there is no separate county building office; Bonner Springs, Edwardsville and Lake Quivira kept their own city governments and issue their own permits. The first thing to establish on any project here is the state: Kansas City, Missouri is a different, larger city under an entirely different government across the state line, and the two share nothing but a name and a river.
The contractor requirement differs from its Kansas neighbours too. Johnson County issues 11 contractor licence types; the Unified Government instead requires general contractors and subcontractors to hold its business (occupational tax) licence, and electrical, plumbing and mechanical trade masters to hold a master licence with Building Inspection. And because Kansas has no general statewide building code, the editions enforced are those the Unified Government has adopted — its published list (as of 30 June 2022) shows the 2018 International Building, Residential, Mechanical, Fire and Energy Conservation Codes, the 2018 Uniform Plumbing Code and the 2017 National Electrical Code — which should be confirmed from its own ordinance.
This guide covers Kansas City, Kansas and Wyandotte County, which are one consolidated jurisdiction. Kansas City, Missouri is a separate city in a separate state with its own government and codes; Bonner Springs and Edwardsville sit within the county with their own arrangements.
Two cities, one name, different states. Kansas City, Kansas and Kansas City, Missouri are separate cities under separate governments in separate states. A permit, a licence, a code edition or an inspection from one has no standing in the other. On a project anywhere near the state line, confirming which Kansas City the address sits in is the first task and not a formality.

Kansas City's layer is the whole of it: the adopted codes and amendments, the permit office, the fee schedule, zoning, contractor licensing, and the Unified Government's adopted codes and business licensing.
Typically permit required
- Any construction, alteration, repair, demolition or change of occupancy under the codes the Unified Government has adopted
- A business licence for contractors, and a master licence with Building Inspection for electrical, plumbing and mechanical trade masters
- Electrical, plumbing and mechanical work, each on its own permit under the locally adopted trade codes
- New buildings, additions and any structural work on an existing building
- Alterations, repairs and renovations, and any change of occupancy
- Decks, accessory structures above the local threshold, retaining walls, storm shelters and swimming pools
Often exempt
- Ordinary repairs and work the adopted code places below the permit threshold — confirm against the Unified Government's own ordinance
- Ordinary repairs that do not alter structure, egress or systems
- Direct like-for-like replacement of a fixture, where the local jurisdiction allows it without a permit
- Painting, papering, flooring, cabinets and similar finish work
- Small accessory structures below the local threshold — the zoning ordinance still applies
What is actually local, and what is not
Locally, what stands out is the consolidated city-county government and the business licence it requires of contractors.
Kansas has no general statewide building code: each city and county adopts and amends its own. A few state rules apply everywhere, led by the Kansas Fire Prevention Code. Kansas rules
Who handles permitting in Kansas City?
The Unified Government is the permitting authority for Kansas City, Kansas and the rest of Wyandotte County outside Bonner Springs, Edwardsville and Lake Quivira, which permit their own. Its Building Inspection division enforces the codes it has adopted and licenses trade masters, and its business licensing office issues the business licences contractors require. The Kansas State Board of Technical Professions sets the threshold for sealed drawings, and the Office of the State Fire Marshal enforces the Kansas Fire Prevention Code, the one mandatory statewide instrument.

Permit types
Residential permits
A Kansas City, Kansas house project files with the Unified Government against the codes it has adopted, with the contractor holding a current business licence. Because Kansas has no state code, the applicable editions and amendments come from the Unified Government's ordinance rather than from a model code or from practice across the state line.
Commercial permits
Commercial work in Kansas City, Kansas — the Legends and Village West development, the industrial land along the river and the downtown — clears zoning and site development, then plan review against the adopted codes, with sealed drawings where the state board's threshold is met and the State Fire Marshal reviewing the occupancies within its jurisdiction.
Verifying the code before design
In Kansas City, Kansas the Missouri and Kansas river confluence brings substantial floodplain into the file, the levee system governs a good deal of the industrial bottoms, and the Kansas Fire Prevention Code applies as the one mandatory statewide instrument. An assumption that a neighbouring city's code is the same is the most common and most expensive mistake made in Kansas permitting.
Kansas has no state licence for general contractors or the main trades; cities and counties license them under state rules. Roofers register with the Attorney General. Kansas rules

Kansas City, Kansas reviews through the Unified Government against the codes it has adopted. What delays a file here is a project confused with the Missouri city across the line, a design built to a model code without checking the local adoption, and floodplain or levee questions raised late on the river bottoms.
Inspections in Kansas City
Inspections follow the sequence of the codes the jurisdiction has adopted — footing, foundation, framing, rough trades, insulation and final — requested from the city's inspection division by permit number, with the trades inspected on their own permits. Work that passes final receives a certificate of occupancy for new buildings and changes of occupancy. Kansas City, Kansas inspects in the sequence the adopted codes set, through the Unified Government's inspectors, with the trades inspected on their own permits and the certificate of occupancy following the finals.

Is this the same as Kansas City, Missouri?
No. They are separate cities under separate governments in separate states; a permit, licence or code edition from one has no standing in the other.
Is the county a separate jurisdiction?
No. Wyandotte County and Kansas City, Kansas are consolidated into one unified government. Bonner Springs, Edwardsville and Lake Quivira remain separate cities and permit their own construction.
What licence does a contractor need?
A business (occupational tax) licence from the Unified Government for general contractors and subcontractors, and a master licence with Building Inspection for electrical, plumbing and mechanical trade masters.
Which code editions apply?
Those the Unified Government has adopted. Kansas has no general statewide building code, so the local ordinance is the governing document.
Is anything mandatory statewide?
Mainly the Kansas Fire Prevention Code, enforced by the State Fire Marshal, which a local jurisdiction may make more stringent but not less. It does not cover one- and two-family homes.
Does a licence from another Kansas county work here?
Kansas licences are local and generally do not transfer; confirm the Unified Government's own requirement before pulling a permit.
