ADU rules in Gladstone, MO — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Missouri has no statewide ADU mandate, so accessory dwellings in unincorporated Clay County are controlled by county zoning under Title XV and require a building permit. Placement, size, and use must conform to the parcel's zoning district.
Clay County zones its unincorporated area under Title XV of the county code, and a second dwelling or accessory living unit must conform to the parcel's zoning district and receive a building permit from the Building Division. Missouri sets no statewide ADU requirement, so there is no right to add one. A unit with a kitchen and bathroom is habitable space under the adopted International Residential Code, needing egress, ceiling height, ventilation, and approved water and wastewater service. Rural parcels on septic must show the system can handle the added load, and subdivision deed restrictions frequently prohibit second dwellings.
Adding or occupying an unpermitted accessory dwelling brings code-enforcement action and possible orders to legalize or remove it. Overloading a septic system triggers health-department correction.
