Overland Park does not impose traditional municipal impact fees on residential ADUs. Costs are limited to building permit fees, plan-review fees, separate trade permits, and connection fees if a new water or sewer service is required (WaterOne for water, Johnson County Wastewater for sewer). Kansas law does not authorize school impact fees on residential development. Johnson County Appraiser will reassess the property after construction.
Overland Park's fee structure is set by City Council resolution and the UDO/OPMC permit-fee schedule administered by Planning + Development Services. Standard building permit fees scale with construction value — typical small detached ADU permits run in the $400-$1,200 range in the Kansas City metro, with separate electrical, plumbing, and mechanical trade permits priced individually. Plan-review fees typically add a percentage of the base building permit fee. Overland Park is served by WaterOne (Johnson County's water utility, headquartered in Lenexa) for water service and by Johnson County Wastewater (a separate county utility) for sanitary sewer — connection or capacity fees apply only when a new water meter or sanitary tap is required; sharing the existing service with the principal dwelling avoids new connection charges. Natural gas is supplied primarily by Atmos Energy or Kansas Gas Service depending on the neighborhood; electric is Evergy. Kansas has not adopted a statewide development impact-fee enabling statute analogous to California's Mitigation Fee Act or Idaho's Development Impact Fee Act, so Overland Park does not levy parks, transportation, or school impact fees on ADU construction. The Johnson County Appraiser (111 S. Cherry Street, Olathe) will reassess the property after construction, raising annual property tax based on the increased improvements value. Stormwater fees billed through the City may increase if impervious surface significantly grows.
Failure to pay required permit fees results in permit denial or revocation. Unauthorized utility connections lead to disconnection plus penalty fees billed by WaterOne or Johnson County Wastewater. Unpermitted construction discovered later faces doubled fees plus enforcement penalties under the OPMC permit-fee schedule.
