Build Guide: Kansas City, Missouri

Historic review is triggered by the local register, not the National Register

The Historic Preservation Commission reviews exterior changes to properties that are local landmarks or sit within local historic districts, and a Certificate of Appropriateness must be issued before an exterior building permit. The trigger is listing on the Kansas City Register of Historic Places. The city states plainly that the Commission does not review properties listed on the National Register of Historic Places, which is a common and consequential misunderstanding.

The Commission meets monthly, typically on the last Friday at 9 a.m., and publishes a rolling twelve month calendar of meeting dates with matching application deadlines. The deadlines are not a fixed number of days ahead, so the calendar has to be checked per project. Applications go through CompassKC and are reviewed against the city’s Urban Design Guidelines, which are based on the Secretary of the Interior’s Standards.

Some work is approved by staff, some needs the full Commission

The city publishes a Design Review Table setting out which applications for a Certificate of Appropriateness staff can approve administratively and which go on a Commission agenda. In broad terms, like-for-like work on a contributing building, such as roof replacement in the same material, paint color changes, porch flooring and railing replacement, in-kind window replacement, and small additions that are not street facing, tends to be administrative.

Work that changes materials or the street-facing appearance, along with demolition of a primary building and new infill construction, tends to require the full Commission. For a non-contributing building in a district, far more is handled administratively. Because the table is revised over time, check the current version against a specific scope rather than assuming.

Every demolition of a building over 50 years old is reviewed

Under Ordinance 241070, adopted December 19, 2024, Kansas City reviews all proposed demolitions of buildings over 50 years old for historical and cultural significance. Structures declared dangerous under Chapter 56, Article V of the city code are exempt. Historic Preservation Office staff first evaluate whether the structure would qualify for listing.

If it would not, a notice of administrative approval goes to the Commission and the neighborhood association, and if the Commission does not request review within seven days the approval becomes final. If the structure does meet listing criteria, the Commission may impose a 45 day delay on demolition so alternatives can be considered, after which demolition may proceed. Inside a local historic district, demolition of a primary building requires full Commission review regardless of age.

Platted building lines often govern the setback

The single-family districts set minimum lot area at 7,500 square feet in R-7.5, 6,000 in R-6, and 5,000 in R-5, with minimum lot widths of 50, 50, and 45 feet. Maximum height is 35 feet in all three, and each requires a minimum of 30 percent open space rather than stating a maximum lot coverage.

Front and rear setbacks are expressed as 25 percent of lot depth and side setbacks as 10 percent of lot width, each subject to a maximum required dimension. The city’s zoning information bulletin states that the front yard need not exceed 30 feet in R-10, R-7.5, and R-6, or 25 feet in R-5 and R-2.5, and that a side yard need not exceed eight feet, rising to 15 feet where the yard abuts a street. What matters more in practice in the Country Club District is that the setback is the greater of the zoning requirement or the platted building line. No more than 40 percent of the front yard and 20 percent of the street side yard may be paved.

Infill construction is measured against the block

Section 88-110-07, effective January 17, 2023, applies to any residential development on an infill lot with eight or fewer units, including new construction and modifications to an existing structure. The context area is every lot lying wholly or partly within 200 feet of the subject property on the same block face.

The front setback must be no less than and no greater than the setback provided by the existing residential buildings in that context area. Height is set at 12 feet per story of the greater of the two nearest residential buildings of the same type, with an additional six feet permitted where the roof pitch falls in the range the ordinance specifies. Lot coverage is capped at 50 percent and impervious cover at 75 percent, and lot area must fall between 75 and 150 percent of the context area average. On an older Missouri-side block this rule, not the zoning table, is usually what sets the envelope.

Tree rules mostly do not reach a single house

Kansas City adopted tree preservation requirements under Ordinance 220961, passed March 16, 2023, with a citywide 35 percent canopy goal. They are triggered by land disturbance permits covering an acre or more, by development requiring approval such as a rezoning or preliminary plat, and by building permits disturbing more than 10,000 square feet where no development plan approval is required.

An application for a building permit for a single-family detached house on a single previously platted lot is expressly excluded. In practice that means no city tree removal permit is required to take down a tree on a typical private residential lot. Trees in the street right of way are a separate matter, handled by KC Parks Forestry and Conservation, which issues permits to plant, prune, or remove at no cost to the resident.

Realistic timelines

The city states the permit clock plainly: construction must begin within 180 days, and the permit must receive at least one inspection for each 180 days following issuance. Permits that have not begun work or have not had an inspection within 180 days will expire. The city does not publish extension rules on its development guide, so those are worth confirming for a specific project. Kansas City enforces the 2018 International Residential Code and the 2021 International Energy Conservation Code.

The sequence runs zoning and floodplain check, plan submittal through CompassKC, plan approval, permit application, fee payment, then construction. Plan check is charged at one half the building permit fee. Plan review is not required for non-load-bearing wall installation, window or door replacement under four feet wide, interior remodeling without structural changes, or repair in kind. Where a Certificate of Appropriateness is needed, it comes before the exterior permit, so the Commission calendar sits in front of everything else.

Homes association covenants apply on top of city rules

Private deed restrictions and homes association architectural review were a defining feature of the Nichols Country Club District and remain in force across much of Brookside and the Ward Parkway corridor. The Armour Hills Homes Association, for example, states that building activity is governed both by Kansas City codes and by the association’s own restrictions and covenants.

These are private agreements. The city does not administer them, they can be stricter than city rules, and they can apply where no city review is triggered at all. Establishing which association covers an address, and what its covenants require, belongs at the front of a project rather than the middle.

Contractors need a business license, a certificate, and a license

Missouri has no statewide general contractor license, so this is entirely municipal. Kansas City requires three things: a business license from the Finance Department, a Certificate of Qualification held by a qualified individual in the trade, and a Contractor License held by the business. A Residential Building Contractor license covers constructing or altering one and two family dwellings and townhouses. Certification and licensing run through CompassKC.

Insurance and deposit requirements, including minimum liability limits and the terms for a qualified supervisor, are set out in the city’s information bulletins rather than in the code itself, so confirm the current figures with the Contractor Licensing office. Demolition contractors are separately licensed as Class I or Class II depending on the size of structure.
