Kansas City Zoning & Permits

Is Kansas City, MO the same as Kansas City, KS?

No — these are two separate cities in two different states. Kansas City, Missouri (KCMO) is in Jackson County, Missouri and is the larger city with approximately 508,000 residents. Kansas City, Kansas (KCK) is in Wyandotte County, Kansas and is a separate municipality. They share a metropolitan area but have completely different city governments, zoning codes, building departments, and permit offices. This page covers Kansas City, Missouri only. For Kansas City, Kansas, contact the Unified Government of Wyandotte County/Kansas City, Kansas.

Can I build an ADU (accessory dwelling unit) in Kansas City, MO?

Yes. Kansas City's Zoning and Development Code (Chapter 88) allows ADUs in residential zones. Detached ADUs are limited to 1,000 sqft and must be located in the rear yard. No owner-occupancy is required. One additional parking space is typically required unless the property is near a transit corridor.

What permits does Kansas City require for a home addition?

A building permit from the Kansas City Permits Center is required for all structural additions. Submit applications through the PermitKC online portal. You'll need site plans, construction drawings, property ownership documentation, and a completed permit application. Fees are based on construction value. Review takes approximately 3-6 weeks. Inspections are required at foundation, framing, electrical, plumbing, and final stages.

Does Kansas City have special rules for short-term rentals in neighborhoods like Crossroads or River Market?

STR rules are citywide — Kansas City requires a Short-Term Rental Registration ($75/year) for all rentals of 30 consecutive days or fewer. Crossroads Arts District and River Market are popular Airbnb and VRBO locations. Both hosted (room rental with owner present) and non-hosted (whole-home) rentals are permitted with registration. Contact the Kansas City City Clerk's office for current registration requirements.

What are Kansas City's zoning rules for home-based businesses?

Kansas City allows home occupations without a separate permit in residential zones. Rules include: no exterior signage, no customers on premises in R-1 through R-3 zones, no non-resident employees, and no more than 25% of floor area used for business. Missouri's Cottage Food Law allows home-based food production with up to $50,000 annual revenue without a permit. Contact Kansas City Planning at (816) 513-2555 for specific use questions.
