Overview
Code type
hybrid-pd
Naming convention
mixed
Kansas City adopted Chapter 88 Zoning and Development Code in 2011 — a hybrid use-based + form-based structure. Residential lot-size-indexed districts (R-80, R-20, R-10, R-7.5, R-6, R-5, R-2.5) coexist with form-based district frameworks for downtown and selected corridors. Charter city; Jackson County is also a home-rule charter county (Art. VI §18). Overlay framework is extensive (Chapter 88 §200 series): Adult Entertainment (CXO §88-210), Special Character Districts (§88-215), Neighborhood Conservation (NCO §88-225), Pedestrian-Oriented (PO §88-230), Historic (HO §88-235), Shoal Creek environmental special-purpose (§88-255), Urban Redevelopment, plus corridor and TOD overlays. Active rental-registration / source-of-income discrimination history — directly affected by HB 595 (2025) source-of-income preemption.
Worth knowing
- Underground Space District (§88-265) is unique nationally — KC sits atop 50+ million sf of repurposed underground limestone mines zoned independently from surface parcels. One of the few instances of 3D urban zoning in the US.
- KCI Airport is a standalone zoning district (KCIA §88-275), not an overlay — assigns distinct base-equivalent zoning to airport and surrounds. Most cities use overlay approach instead.
- Westport has its own named overlay chapter (§88-285) with building composition, site design, and sign standards — form-based code level of detail, unusual for an overlay.

State preemptions
MO RSMo Chapter 89 (Zoning and Planning)applies
Qualifying condition
RSMo Chapter 89 §§89.020-89.110 (Standard State Zoning Enabling Act derivative). Constitutional charter city under Mo. Const. Art. VI §19 (charter adopted 1925; amended periodically). Population ≈ 508,000.. Zoning authority derives from Chapter 89 (universal enabling for MO municipalities) layered with home-rule authority where applicable. Citation-date 1939 is a conservative codification-start estimate; Chapter 89 has been continuously in force throughout the modern MO zoning regime.
Effect
Zoning ordinance must comply with §89.040 'in accordance with a comprehensive plan' standard and §89.050 procedural floor (15-day published notice, public hearing, two-thirds supermajority on protest petition). Rezonings subject to §89.060 protest petition (30% area / 30% within 185 ft).
MO RSMo §89.020.2 (manufactured-home appearance preemption)applies
Qualifying condition
RSMo §89.020.2 enacted via SB 644 (2006) — citation flagged for re-verification in preemptions.md retrieval-issues. Permissive preemption: applies to all MO municipalities including Constitutional charter city under Mo. Const. Art. VI §19 (charter adopted 1925; amended periodically). Population ≈ 508,000.. City may adopt reasonable appearance criteria (foundation, pitch, width) for HUD-Code manufactured homes in single-family districts but is not compelled to permit them universally. Status per_parcel_conditional because effective constraint depends on whether the city permits manufactured homes in any single-family district at all.
Effect
If the city permits manufactured homes in any single-family residential district, it may impose reasonable appearance criteria. The city may also lawfully not permit HUD-Code manufactured homes outside designated MH districts so long as zoning is not internally discriminatory.
MO RSMo §700.027 (modular-unit state code equivalence)applies
Qualifying condition
RSMo §700.027 — Statewide modular-unit state code; equivalence with site-built. Applies to all MO municipalities. Citation-date 1986 is a conservative estimate for chapter codification — re-verify against revisor.mo.gov for exact enacting session law.
Effect
Modular units (built to MO state code) are treated as equivalent to site-built dwellings; cannot be excluded from districts that permit site-built dwellings of the same type.
MO Hancock Amendment — Mo. Const. Art. X §§16–24applies
Qualifying condition
Mo. Const. Art. X §§16–24 (Hancock Amendment; 1980 voter initiative). Statewide constitutional limit. Applies to Constitutional charter city under Mo. Const. Art. VI §19 (charter adopted 1925; amended periodically). Population ≈ 508,000. for any new fee or fee increase since 1980-11-04 (per Keller v. Marion County Ambulance District, 820 S.W.2d 301 (Mo. banc 1991) five-factor fee/tax test). Materially constrains impact-fee adoption — most MO cities do not levy transportation/parks impact fees under the Keller framework.
Effect
City may not levy a new tax/license/fee or increase existing such revenue source above 1980-11-04 level without voter approval. Practical effect on zoning: building-permit and plan-review fees OK if cost-of-service; transportation/parks impact fees structurally difficult under Keller test; no general MO impact-fee enabling statute. Capital infrastructure funding typically via TIF/CID/TDD or voter-approved sales-tax mechanisms (§94.577) rather than impact fees.
MO RSMo §89.145 (group homes for persons with disabilities)applies
Qualifying condition
RSMo §89.145 — Statewide. Applies to all MO municipalities including Constitutional charter city under Mo. Const. Art. VI §19 (charter adopted 1925; amended periodically). Population ≈ 508,000.. Parallels federal Fair Housing Act but codified at state level. Citation-date 1989 is a conservative estimate — re-verify enacting session law against revisor.mo.gov.
Effect
Municipalities may not prohibit group homes of ≤8 unrelated persons with disabilities in any single-family zone.
MO HB 595 (2025) — source-of-income discrimination preemptionapplies
Qualifying condition
HB 595 (2025, 103rd G.A., 1st Reg. Sess.; Brown / Schroer), signed by Gov. Kehoe, effective 2025-08-28. Statewide — applies to all MO municipalities. Preempts municipal source-of-income discrimination ordinances and local restrictions on landlord background-check / security-deposit / right-of-first-refusal practices.
Effect
City cannot enact or enforce a source-of-income discrimination ordinance restricting landlord refusal based on tenant income source (including Section 8 vouchers). Tenant-screening / landlord-tenant practice rather than land use per se, but operates adjacent to fair-housing zoning policy.
MO RSMo Chapter 64 (county planning, zoning, recreation) — ETJ interactionapplies
Qualifying condition
RSMo Chapter 64 — Jackson County operates county zoning (or charter zoning if home-rule) under Chapter 64 class-specific subchapters. Applies only to UNINCORPORATED portions; does not directly preempt Constitutional charter city under Mo. Const. Art. VI §19 (charter adopted 1925; amended periodically). Population ≈ 508,000. zoning within municipal limits. Status per_parcel_conditional because effective constraint depends on whether the parcel sits inside or outside corporate limits.
Effect
County zoning controls land in unincorporated portions of the county and may affect the city's extraterritorial jurisdiction (ETJ) interactions and annexation patterns. Within municipal limits, Chapter 89 (not Chapter 64) governs.
Non-applicable laws (1)
MO statewide STR preemption (none in force)does_not_apply
Qualifying condition
No codified statewide STR-preemption statute. Bills SB 415/HB 615 (2024), SB 742/HB 482 (2025), refiled in 2026 session — none enacted as of 2026-05 review. SB 1066/HB 1768 (2026) passed both chambers, awaiting gubernatorial action — property-tax classification of STRs, not zoning preemption. Sentinel effective_date 1900-01-01 used to flag 'no enacting date'.
Effect
City retains full Chapter 89 / home-rule authority to regulate, cap, or prohibit short-term rentals subject only to federal constitutional and state uniform-ordinance constraints. Watch list: 2026 session HB 5529–5585 zoning-preemption block (posted to House Government Operations May 2026; outcome pending) and SB 1066/HB 1768 STR property-tax classification.

Quirks & notes
- Underground Space District (§88-265) is unique nationally — KC sits atop 50+ million sf of repurposed underground limestone mines zoned independently from surface parcels. One of the few instances of 3D urban zoning in the US.
- KCI Airport is a standalone zoning district (KCIA §88-275), not an overlay — assigns distinct base-equivalent zoning to airport and surrounds. Most cities use overlay approach instead.
- Westport has its own named overlay chapter (§88-285) with building composition, site design, and sign standards — form-based code level of detail, unusual for an overlay.
- Infill residential development standards (§88-110-07) create parallel lot/building standards for infill contexts, reducing mismatch between code standards and existing built fabric.
- 2025 parking reform (Ord. 260219) overhauled §88-420: added maximum parking ratios (significant departure from minimum-only codes), updated bicycle parking, reduced parking near transit.
- Downtown FAR/height bonus system (§88-130-07) is menu-based — developers earn additional floor area/height by providing affordable housing, public open space, or public amenities.
- 2011 hybrid code intentionally blends use-based and form-based approaches — downtown/commercial districts regulate form more explicitly while residential/industrial remain conventionally use-based.
- R-number naming likely encodes lot size in 1,000s sf for larger districts (R-80 = 80,000 sf) but shifts to density index at smaller numbers — not confirmed from code text.
- Hybrid use-based + form-based code (Chapter 88, 2011 adoption) — uncommon in MO and broader Midwest; more comparable to Denver or Minneapolis than to St. Louis.
- Source-of-income discrimination ordinance (KC Ord. 231019, 2024) directly preempted by HB 595 (2025) effective 2025-08-28. Material change to landlord-tenant practice though not strictly zoning.
- Jackson County is a constitutional charter county (Mo. Const. Art. VI §18) — adds a second home-rule layer above standard Chapter 64 county zoning.
- KCI Airport overlay constraint extends across north-of-river annexed land; pairs with FAA Part 77 imaginary surfaces.
- Shoal Creek Special District (§88-255) is a comprehensive standalone special-purpose district that replaces underlying zoning for covered parcels — distinct from overlay.
- STR regulation: registration regime with owner-occupancy distinction and density caps; litigation history (2019-2022) upheld most provisions. No statewide preemption in force; HB 5529-5585 watch list.

MO-RSMo-64 noted with Jackson County charter-county special status (Art. VI §18). MO-HB-595-2025 is materially impactful for KC — directly preempts the 2024 KC source-of-income discrimination ordinance (KC Ord. 231019); recorded as confirmed/applies with KC-specific qualifying_condition. MO-HANCOCK noted: KC operates substantial TIF/CID/TDD financing in lieu of impact fees per the MO-wide pattern. MO-STR-preemption-not-enacted noted: KC has its own STR registration regime with owner-occupancy distinction and density caps in certain districts (litigation history 2019-2022 upheld most provisions). |
