Kansas City Setbacks & Height Limits — Residential Zones

Last updated: Verified:

Fact-checked against Kansas City's current Zoning and Development Code and Information Bulletin 121, revised October 3, 2025 and current during this September 2026 review.

Kansas City's residential setback rules are not a single 25-ft front / 5-ft side / 15-ft street-side / 25-ft rear pattern. For conventional one- and two-family development in common R districts, the current code uses percentages of lot depth and width, with maximum required setbacks.

Current Conventional Residential Standards

Kansas City Information Bulletin 121 summarizes current requirements for conventional development in R-10, R-7.5, R-6, R-5, and R-2.5:

Standard Current Rule
Front setback 25% of lot depth
Maximum required front setback 30 ft in R-10/R-7.5/R-6; 25 ft in R-5/R-2.5
Interior side setback 10% of lot width, but need not exceed 8 ft
Street-side setback 15 ft
Rear setback 25% of lot depth
Maximum required rear setback 30 ft in R-10/R-7.5/R-6/R-5; 25 ft in R-2.5

The previous page's universal 25/5/15/25-ft table was therefore inaccurate.

Current Lot Sizes

Current Table 110-2 lists conventional minimum lot areas of:

Zone Minimum Lot Area
R-10 10,000 sq ft
R-7.5 7,500 sq ft
R-6 6,000 sq ft
R-5 5,000 sq ft
R-2.5 4,000 sq ft

R-2.5 also permits more than one dwelling unit under the applicable lot-area-per-unit and building-type standards. Do not interpret the district number as a simple single-family lot-size label.

Infill and Building-Type Standards

Section 88-110 contains separate rules for infill residential lots and for specific building types such as detached houses, zero-lot-line houses, townhouses, two-unit houses, and other forms.

The conventional-development table above should therefore not be copied to every infill or alternative residential project.

Platted Building Lines and Easements

The City's current bulletin expressly warns that platted building lines and easements may require greater setbacks than the base zoning rule.

Always review the recorded plat or survey in addition to Chapter 88.

Height

Maximum height must be checked in the current Table 110-2 and any building-type-specific standards for the exact district and proposal.

The previous page's simplified statement that R-7.5/R-2.5 are 35 ft, R-5 is 45 ft, and R-10 is 80 ft was not a reliable description of the current residential code and has been removed.

Overlays and Special Conditions

Historic Overlay districts, Neighborhood Character Overlays, Pedestrian-Oriented Overlays, park/boulevard/parkway regulations, airport controls, UR/MPD plans, and other special districts can modify the base result.

How to Check a Property

  1. Confirm the exact zoning district in the City's zoning map.
  2. Determine whether the project is conventional development, infill, or another residential form.
  3. Use §88-110-06 and current Table 110-2.
  4. Check platted building lines and easements.
  5. Check overlays and approved development plans.
  6. Confirm parcel-specific questions with Kansas City Planning & Development.

FAQ

What are the setback requirements in Kansas City?
Setbacks in Kansas City are set by Chapter 88 of the Zoning and Development Code and vary by district. In typical single-family residential zones such as R-7.5 and R-2.5, expect a front setback around 25 ft, interior side setbacks around 5 ft, and a rear setback around 25 ft. Always verify your specific zone with Kansas City Planning & Development.
What is the maximum building height in Kansas City residential zones?
Under Chapter 88, maximum building height in low-density residential districts (R-7.5, R-2.5) is typically 35 ft, measured from average grade to the highest point of the roof. Multi-family districts (R-5, R-10) allow 45 ft to 80 ft. Overlay districts and design review can lower these limits.
Does Missouri state law override Kansas City setback or height rules for ADUs?
No. Missouri has no statewide ADU preemption law, so Kansas City's locally adopted ADU standards in Chapter 88 control. ADUs must meet the base district setbacks and height limits. See the Kansas City ADU Rules page for details.
How do I look up my property's specific setback and height requirements?
Identify your zoning district by contacting Kansas City Planning & Development at (816) 513-1500 or reviewing the Chapter 88 district regulations on Municode. Then read the district's bulk standards section for front, side, and rear setbacks, height, and lot coverage. Check for overlay districts that may modify the base rules.
