How building permits work in Kansas City

Kansas City, MO building permits are issued by the Regulated Industries Division under the city's IBC-based Building and Trade Code. A one-stop permit center at City Hall Annex handles building, mechanical, plumbing, and electrical permits together. Historic Landmarks districts — including Westport and Valentine — require Landmarks Commission review for exterior changes. Missouri state contractor licensing is verified at intake.

Typical permitting sequence

  1. 1

    Verify zoning & Landmarks districts

    Check the KCMO Zoning & Development Code district and identify whether the property is in a Landmarks district (Westport, Valentine, Midtown) or subject to the Crossroads Arts District design overlay guidelines.

  2. 2

    Landmarks Commission review

    For exterior changes in a designated Landmarks district, apply to the KCMO Landmarks Commission for a Certificate of Appropriateness before submitting to Regulated Industries. Commission meets monthly.

  3. 3

    Pre-application meeting

    Recommended for commercial projects, multi-family, or any project in a Landmarks district. Regulated Industries staff can confirm submittal requirements and identify potential issues.

  4. 4

    Submit via KC PlanReview portal

    File through the KC PlanReview online portal with IBC-stamped drawings, contractor Missouri state licenses, Landmarks Commission decision (if applicable), and stormwater/sewer agreements from KC Water for new construction.

  5. 5

    Plan review

    Regulated Industries reviews for KCMO Zoning Code compliance, IBC/IRC structural, fire, MEP, and accessibility. Correction cycles through the portal.

  6. 6

    Permit issuance

    Building, mechanical, plumbing, and electrical permits can be issued simultaneously at the permit center. Post permit on site.

  7. 7

    Inspections & CO

    Schedule inspections through the KC inspection portal: foundation, framing, MEP rough-in, insulation, final. Certificate of Occupancy issued after all inspections pass.

Common permit categories

  • • Building Permit (Residential / Commercial)
  • • Mechanical
  • • Plumbing
  • • Electrical
  • • Sign
  • • Demolition
  • • ADU

Local considerations

  • • ADUs have been allowed city-wide since a 2020 ordinance — no special use permit required for accessory dwelling units on single-family lots.
  • • Missouri requires state contractor licensing through DOLIR — verify license status on the Missouri Secretary of State portal before pulling permits.
