Olathe, KS
Johnson County
UDO Sec. 18.50.025 governing Olathe ADUs does not contain an express owner-occupancy mandate. ADUs must remain accessory to a principal single-family dwelling on the same lot, which preserves the single-family character but does not on its face require the owner to live in either unit. Applicants should confirm current interpretation with the Olathe Planning Division.

Johnson County
Overland Park's Unified Development Ordinance (Title 18 OPMC) frames the ADU as a subordinate accessory use to the principal single-family dwelling. The accessory-use framework typically requires the owner to occupy either the primary dwelling or the ADU, verified at certificate of occupancy. HOA covenants in newer Overland Park subdivisions may add stricter rules under KSA 58-3801 et seq. (Kansas Uniform Common Interest Owners Bill of Rights Act).

Olathe FAQ
Must I live in the home to have an Olathe ADU?
The publicly published text of UDO Sec. 18.50.025 does not contain an express owner-occupancy requirement. The ADU must be accessory to a principal single-family dwelling on the same lot, but the section does not on its face require the owner to reside in either unit. Confirm current interpretation with the Olathe Planning Division before relying on this.
Does Kansas state law require owner occupancy or limit rentals?
No. Kansas has no statewide ADU statute. KSA 12-741 et seq. delegates zoning authority to cities, so owner-occupancy is purely a local question. The UDO does not expressly bar non-owner-occupied operation, but standard landlord-tenant duties under the Kansas Residential Landlord and Tenant Act (KSA 58-2540 et seq.) apply.
Overland Park FAQ
Can I buy an Overland Park property and rent both the main house and the ADU?
Generally no in standard single-family districts. The UDO's accessory-use framework treats the ADU as subordinate to the principal dwelling, with the owner typically required to occupy one of the two units. Investors should confirm current standards with Planning + Development Services before structuring a dual-rental arrangement, especially given the ongoing UDO update begun in 2024.
How does Overland Park verify ADU owner occupancy?
At certificate of occupancy and on complaint, Planning + Development Services and the Community Services Division may request proof such as a Johnson County homestead exemption filing (KSA 79-201x), voter registration showing the address, or a Kansas driver's license listing the property as the owner's primary residence.
