The short answer: rewiring requires a permit in every Kansas City-area jurisdiction we checked. The permit is generally issued by the city where the house is located; a county may handle unincorporated addresses — and it is pulled by a contractor licensed in that jurisdiction or, in some cities, by an owner-occupant doing the work personally. Expect an inspection before walls are closed and a final inspection. The cities are on different editions of the National Electrical Code, which changes a few requirements (notably the outdoor emergency disconnect on a replaced service). Service upgrades also involve the utility, and which utility depends on the address.
Why “Kansas City” isn’t one jurisdiction
The metro straddles two states and dozens of cities. For electrical work, the relevant facts are:
- Missouri adopts building and electrical codes city by city. It offers a voluntary statewide electrical contractor license; a city “shall recognize a statewide license in lieu of a local license,” but may keep its own licensing for everyone else and continues to issue permits, inspect and enforce its own code. (RSMo 324.925; Missouri Division of Professional Registration)
- Kansas has no statewide electrical license at all. Licensing is by county or city — in the metro, mainly the Johnson County Contractor Licensing program and the Unified Government of Wyandotte County.
- Each city adopts its own code edition. As of October 2026, Overland Park, Independence, Lee’s Summit and Mission publish the 2023 NEC; Kansas City, Missouri, Kansas City, Kansas, Prairie Village, Lenexa and Raytown publish the 2017 NEC. Local amendments and permit-effective dates still matter.
Jurisdiction by jurisdiction
Kansas City, Missouri
Permit: required for “most electrical” work; the city’s stated exemptions are minor items like “replacing a light switch or light fixture.” Rewiring is not exempt. (KCMO City Planning & Development, electrical permits)
Who pulls it: a contractor licensed by the city. The one exception: “If you own a single-family dwelling, you are authorized to obtain permits for any work on the premises if you occupy the dwelling and perform the work yourself.” Rentals and duplexes aren’t covered by that provision; “other persons requesting permits to do electrical, plumbing or heating and ventilating work must be licensed contractors.” (same page)
Contractor licensing: three steps — a city business license, a Certificate of Qualification, then the Contractor License through CompassKC; electrical certifications are Electrical Supervisor, Master Electrician and Master Limited Electrician. (KCMO contractor licensing) Ask your contractor for the KCMO license number and verify it with the Permits Division.
Portal and inspections: CompassKC for permits and inspection scheduling; Permit Center at 414 E. 12th St.; “City inspectors will inspect the project throughout the construction phase as required by code.” For a remodel, “you will also need to submit permit applications for each trade,” and a permit expires after 180 days without inspection activity. (KCMO code questions)
Code: 2017 National Electrical Code with local amendments, adopted in Chapter 18, Sec. 18-74. The I-code package and the electrical code have different edition years; a proposed replacement package does not change the edition currently adopted. Confirm the edition applicable to your permit when plans are submitted. (KCMO adopted codes; Chapter 18, Sec. 18-74)
Fee: the city’s published Sec. 18-20 one- and two-family valuation schedule starts at $52 through $1,000, then $58 through $2,000, plus $4.33 for each additional $1,000 or fraction through $100,000. At a city-accepted valuation of $20,000, that gives a $135.94 base permit fee; at $30,000, $179.24. These examples are not the complete permit invoice: additional reviews, inspections or other charges may apply. Ask the contractor to confirm the current assessment with the city. (City Clerk, adopted Ordinance 220612, Sec. 18-20)
Historic properties: historic design review applies to “exterior changes that will be visible from the public right-of-way” on Kansas City Register properties. Interior rewiring isn’t a listed trigger; a new exterior meter or mast location on a Register property may be. (KCMO historic design review)
Kansas City, Kansas (Unified Government of Wyandotte County)
Permit: required. Any owner or agent who intends to “replace any system; electrical, mechanical, plumbing” must “make application to Building Inspection… and obtain the required permits.” (UG Building Inspection)
Who pulls it / licensing: “Trade masters are required to carry a master’s license with Building Inspections,” and the business also needs a Unified Government occupational license. (UG trade licensing)
Code: 2017 NEC with local amendments, adopted by Sec. 8-125. (UG Code, electrical article)
Application and records: the UG publishes an electrical/mechanical/plumbing permit application, which requests the project value, work description and property use. Existing permit records can be searched in NRC E-Link. Confirm with Building Inspection whether your application can be submitted online, which inspections must happen before covering work, and how final approval reaches BPU. An owner planning to do the work personally should confirm eligibility before applying; do not assume a homeowner exemption covers hired electrical work.
Utility: the Board of Public Utilities — see below. BPU will not set a meter until the UG inspection has passed.
Johnson County, Kansas — the county license plus your city’s permit
Participating cities use the county licensing program; permits come from the applicable city or, for unincorporated addresses, the county. The Johnson County Contractor Licensing program provides a common license for participating cities. Electrical contractors hold a Class DE license: “Class ‘DE’ License shall entitle the holder thereof to perform only electric services.” Application $100; license $225 per type; the firm must have a qualifying individual, general-liability insurance and workers’ compensation (or a notarized waiver). (Johnson County Contractor Licensing — license types) Ask for the Class DE number and verify it with the county licensing office.
The permit then comes from the city:
- Overland Park. “A permit is required for new branch circuits or extension of branch circuits or placing additional fixtures or receptacles on an existing circuit,” and “to add or upgrade an existing electrical service.” Contractors need the Johnson County license; “Homeowner’s (owner-occupied) acting as the contractor for their own personal home projects do not need to be licensed; however, any subcontractors that they hire are required to have a valid Johnson County Contractor’s License.” The current municipal code adopts the 2023 NEC, second printing, with local amendments (OPMC 16.360.100). (Overland Park electrical code) Permits through ePLACE; inspection arrangements through the city. (City of Overland Park)
- Prairie Village. Permit-required electrical items include “wiring,” “panel changeout,” “replace meter can,” “raise mast,” “service upgrade” and “service relocate.” Electrical contractors need the Johnson County license and a Prairie Village contractor license. Code: “2017 National Electrical Code.” Inspections include ground rough-in, building rough-in and final; permits through the city’s OpenGov portal. (City of Prairie Village)
- Mission. A permit is required for “alterations to the electrical, plumbing, mechanical, or irrigation systems”; all contractors must hold the Johnson County license; a Homeowner Installation Affidavit exists for owner work. Mission adopted the 2024 I-codes and “the 2023 edition of the National Electrical Code,” effective October 1, 2026. (City of Mission)
- Lenexa. Ordinance 5890 adopts the 2018 I-codes and the “2017 National Electrical Code.” (City of Lenexa)
- Westwood. No city license; a Johnson County license in the trade is required. (City of Westwood)
- Unincorporated Johnson County. “A permit is required to repair, remove, convert, or replace electrical, gas, mechanical, or plumbing.” The homeowner exemption from using a licensed contractor applies only when “the residence MUST be for the use and occupancy of the homeowner only.” (Johnson County building permits)
- Olathe, Shawnee, Leawood, Merriam, Roeland Park, Fairway and the other Johnson County cities each issue their own permits under the county license; check the city’s building page for its code edition and portal.
Independence, Missouri
Permit: required for electrical work. Code: “The city follows the 2024 IRC, 2024 IBC, and the 2023 NEC.” Contractor licensing and permits run through the city’s online Permits and Application Center. (City of Independence)
Utility: Independence Power & Light, the city-owned utility serving the entire city except Lake City Arsenal. IPL’s service policies state that “new wiring and alterations in wiring are required to be approved by the City’s electrical inspector prior to being served by IPL,” and “the customer shall install an IPL approved meter socket in all cases.” (IPL; IPL Electric Service Policies Manual)
Lee’s Summit, Raytown, North Kansas City
- Lee’s Summit: adopted the 2024 I-codes and the 2023 NEC, effective October 1, 2026. (City of Lee’s Summit)
- Raytown: 2018 I-codes and the “2017 National Electrical Code.” (City of Raytown)
- North Kansas City: lists the 2017 NEC among its adopted construction codes. (City of North Kansas City)
- Gladstone, Liberty, Blue Springs, Grandview and others: check the city’s building department page.
What the inspections check
A rewire typically has two inspection points — a rough-in, before any wall or ceiling is closed, and a final — with a utility release added if the service is replaced. A phased job may need several inspections. The city determines inspection names, stages and scope; agree on that sequence before closing any work.
- Rough-in: how the cable is routed and supported, box placement, protection where cable passes close to the face of framing, fire-blocking restored, grounding, splices only inside accessible boxes, and no energized knob-and-tube left where insulation will enclose it. Nothing gets patched until this passes — which is why the schedule shows a gap between “cable in” and “walls closed.”
- Final: devices installed, receptacle spacing, GFCI/AFCI operation, tamper-resistant receptacles, panel labeling, the emergency disconnect where required, and the abandoned-wire disposition the scope called for.
- Failed inspection: the inspector lists corrections; the contractor fixes and re-requests. It costs schedule; some cities charge a re-inspection fee, so check the city schedule and the contract for who pays it.
Service upgrades and the utility
A service upgrade — potentially including the meter base, service-entrance conductors, mast or lateral, main disconnect, grounding and panel — needs the utility to disconnect and reconnect, and the city inspection sits between. Which utility:
| Utility | Territory (summary) | What they require |
|---|---|---|
| Evergy | Most of the Missouri side outside Independence (Evergy’s Metro tariff covers parts of Jackson, Clay, Platte and Cass counties); most of Johnson County, Kansas. Evergy has four service areas — check your bill. | Service upgrades go through the online Meter & Service Request form; the customer furnishes a meter socket from Evergy’s approved list; residential standards are published in Evergy’s ESSentials packet. (Evergy; Evergy service areas) |
| Kansas City Board of Public Utilities (BPU) | Kansas City, Kansas / Wyandotte County | “KCBPU cannot set the meter or establish service until the Customer’s installation has passed inspection and KCBPU has been notified of approval by the inspecting authorities.” Meter relocation or replacement is at the customer’s expense; “new meters shall not be installed indoors.” (BPU Electric Service Policies) |
| Independence Power & Light | City of Independence (except Lake City Arsenal) | City electrical inspector approval before service; IPL-approved meter socket. (above) |
| Platte-Clay Electric Cooperative | Rural Northland — Platte, Clay, Clinton and nearby counties | Co-op procedures; contact the co-op. (Platte-Clay) |
| Osage Valley Electric Cooperative | Parts of Cass and counties to the south | Co-op procedures. (Osage Valley) |
Two common misconceptions: not every rewire needs a service upgrade (branch circuits and the service are separate — see whole-house rewiring), and not every house in the metro is on Evergy. A contractor who assumes either is guessing about your house.
Code editions and what they change for you
The edition matters for a handful of items a homeowner will notice:
- Outdoor emergency disconnect: the 2020 and 2023 NEC include dwelling emergency-disconnect requirements in Sec. 230.85. A service replacement can trigger this work even when branch circuits are unchanged. Ask how the adopted edition and local amendments apply; Overland Park, Independence, Lee’s Summit and Mission now list the 2023 NEC. A city on the 2017 NEC can have separate local or utility requirements, so do not assume the item is excluded. (Overland Park adopted electrical code)
- AFCI, GFCI and tamper-resistant devices: these requirements serve different purposes, and coverage changes between editions. Ask the contractor to list the protection required for the actual branch-circuit additions, extensions or replacements. A room’s age or an existing two-prong receptacle does not answer that question. An inspection checklist illustrates the separate checks, but the applicable Kansas City-area code controls. (City of Saint Paul electrical inspection checklist)
- Existing knob-and-tube and alterations: having an older installation does not tell you whether a particular circuit may remain. Condition, alterations, insulation contact, the adopted code and local enforcement all matter. Have the contractor identify the circuits to replace and how any abandoned conductors will be verified and documented. An insurer’s removal condition may go beyond the permit’s scope.
Lead-safe work is a separate requirement
Paid renovation in pre-1978 housing can fall under lead-safe renovation rules. EPA administers the RRP program in Missouri; Kansas uses its authorized state program. The federal minor-repair exception uses six square feet per room inside; Kansas’s regulation uses six square feet per component. Area alone does not settle eligibility for an exception: demolition, prohibited practices, the type of work and other conditions matter. Ask the firm doing the disturbance which program applies and for its current certification. Details and a planning checklist are in Rewiring finished walls. (EPA minor-repair guidance; Kansas regulations, 28-72-52)
Frequently asked questions
Can I pull my own permit and have an electrician do the work?
Not in Kansas City, Missouri: the owner-occupant permit is only for work you “perform yourself.” Overland Park and unincorporated Johnson County exempt owner-occupants from licensing for their own home, but subcontractors they hire must be licensed — and the licensed contractor normally pulls the permit for work they’re doing. Other cities set their own rule. The clean arrangement everywhere is the contractor’s permit under the contractor’s license.
What if the previous owner rewired without a permit?
Do not assume that a sale cures a missing permit or that a newer panel proves the branch circuits were inspected. Request the permit history, have the electrical work evaluated, and ask the building department how to address undocumented work. The city determines whether permits, access openings, corrections or further inspections are required. Discuss transaction obligations with your real-estate professional.
How much is the permit?
Under Kansas City, Missouri’s published valuation formula, a $20,000 valuation produces a $135.94 base fee before any additional charges. Other cities use their own schedules. Ask for the jurisdiction, valuation and actual permit charges in the estimate.
Does a Missouri statewide license let a contractor work in Kansas?
No. The Missouri statewide license is recognized by Missouri cities. Kansas has no statewide license; a contractor working in Johnson County needs the county Class DE license (and a city license where the city requires one), and in Kansas City, Kansas a Unified Government master’s license.
Who schedules the inspections?
The permit holder should confirm responsibility for scheduling and providing inspection access. Common city portals are (CompassKC in KCMO; ePLACE in Overland Park; OpenGov in Prairie Village). Arrange access to the panel and opened areas with the permit holder; inspection windows and homeowner attendance requirements vary.
