Olathe does not charge a dedicated ADU impact fee, but residential construction is subject to the City's Park Excise Tax and Street/Traffic Signal Excise Taxes adopted under O.M.C. Sec. 15.02.180. Standard building permit fees, plan review, and Johnson County Wastewater connection charges also apply. There is no Kansas statewide ADU fee preemption.
Olathe imposes excise taxes on new residential dwelling units rather than traditional impact fees. The Park Excise Tax, currently $520 per dwelling unit under the 2021 Comprehensive Listing of Fees and Charges (Resolution 21 series), is deposited in the Neighborhood Park Fund for acquisition and development of parks. Street and Traffic Signal Excise Taxes apply at $0.0037 per square foot of land area in single-family zoning districts. Whether the Park Excise Tax applies to a second ADU dwelling unit on an existing platted lot depends on the Finance Department's interpretation of the fee schedule — applicants should confirm with the Building Codes Division (913-971-6200) before permitting. Building permit fees are valuation-based under O.M.C. Sec. 15.02.180, with separate trade permits for mechanical, plumbing, and electrical work. Johnson County Wastewater (a separate utility from the City) charges system connection fees for new sewer service. Kansas has no statewide preemption of municipal residential fees — KSA 12-741 et seq. leaves the question to cities. Property taxes are reassessed annually by the Johnson County Appraiser once the ADU is added to the parcel.
Building without permits or evading the excise tax exposes the project to stop-work orders, double permit fees on after-the-fact applications under O.M.C. Sec. 15.02.180, and code enforcement action. Falsifying valuation to reduce permit fees may trigger municipal court prosecution.
