Overland Park permits accessory dwelling units in eligible residential zoning districts. Key requirements include an owner-occupancy mandate — the property owner must reside in either the primary dwelling or the ADU. Additional parking spaces are typically required for ADU occupants, separate from the main residence's parking.
