    Olathe adopted a Unified Development Ordinance as Title 18 of the Municipal Code in 2014, consolidating zoning and subdivision platting into one regulatory document.

  2. Floating Transit-Oriented Development (TOD) District

    The Olathe UDO includes a floating TOD district that can be applied to parcels within a half-mile of a bus rapid transit (BRT) or commuter-rail station within a designated TOD area or transit corridor in the comprehensive plan. The TOD district envisions pedestrian-oriented 'complete neighborhoods' with mixed housing types, retail, parks, libraries, and schools.

  3. Elevate Olathe Comprehensive Plan (2026)(2026)

    The Elevate Olathe Comprehensive Plan was adopted by the Olathe City Council in April 2026 — the city's first new comprehensive plan in nearly 15 years. It guides growth and development citywide and encourages a mix of housing types along major corridors such as K-7 and 119th Street. The plan's maps, goals, and policies become the basis for future UDO amendments.

    The R-1 (Residential Single-Family) district in UDO 18.20.070 is Olathe's predominant residential zone. It sets minimum lot size, setbacks, height, and accessory-use standards for single-family detached housing across most of the city.

  5. Kansas Cities Zoning Enabling Statute (K.S.A. 12-741 et seq.)

    Olathe exercises zoning authority under K.S.A. 12-741 et seq., the Kansas statute authorizing cities and counties to adopt zoning regulations. Kansas has no statewide ADU mandate or preemption, so any ADU rules are set locally by Olathe's UDO.
