The City's rule

From City Planning & Development's Electrical, Plumbing and Mechanical Permits page (read 24 October 2026):

Job Permit?
Replacing a light switch or light fixture No: "replacing a light switch or light fixture are exempt from requiring a permit"
New circuit, outlet, panel, service change, reconnect Yes
Two-family, multifamily or commercial building Yes, and permits "may be issued only to licensed contractors"
Your own single-family home Yes; you may pull it "if you occupy the dwelling and perform the work yourself"

The page refers to a full list of exempt work; anything not on it needs a permit.

The homeowner exception

The City's Information Bulletin No. 146 (revised 29 August 2023) spells it out. An owner who occupies a single-family home as a principal residence is "authorized to obtain building trades permits (building, electrical, plumbing, mechanical, etc.)", with conditions:

  • The owner, family or friends do the work personally, and the owner signs an affidavit.
  • "Code compliance and field inspections are required as with any similar permits."
  • If you hire an electrician for part of the job, the contractor must be "licensed under Section 18-14" and the licensed subcontractors "must obtain their own permits for their work".

Questions go to the Permit Services or Contractor Licensing Branch at (816) 513-1500.

Fees, applying and inspections

  • Fee. The City says the permit fee is based on the total cost of construction and offers a permit fee estimator; projects valued at $100,000 or more pay in installments, the rest due once plans are approved. We could not read a residential electrical fee table to quote.
  • Apply online in CompassKC.
  • Inspect. "City inspectors will inspect the project throughout the construction phase as required by code." Schedule through CompassKC, by email, or at (816) 513-1500, Option 1, Sub-Option 1.

Before you hire

Look up the address in CompassKC or the City Issued Permits file with the Kansas City building permit search guide, and check the electrician's license as How to check a contractor's license in Missouri shows. Rules elsewhere: electrical work, a panel upgrade, an EV charger. Costs elsewhere: electrical work cost.

What this does not tell you

The City's current permit file names no contractor and its valuation is blank or zero on almost every residential permit, so there are no firm lists or costs. Burglar and security alarm permits filed as electrical count under Other. A new house gets its own electrical permit, so these counts include new construction. Kansas City, Kansas and the other metro cities are not in the file.
