Overland Park, KS Accessory Structures: Carport Rules (2026)

Overland Park's Unified Development Ordinance (UDO, Title 18) treats carports as detached accessory buildings on one- and two-family residential lots. One detached garage or carport per property is permitted, and the structure must observe the same setbacks as the principal dwelling when treated as a primary parking structure. Detached accessory buildings, including carports, are not allowed in any required front or side yard setback area; they may sit in the rear yard provided no part of the structure is closer than 3 ft to an interior property line, closer than 20 ft to a street right-of-way line, or in front of the building setback line. The combined ground area of detached accessory buildings cannot exceed 30% of the rear yard setback area, and no more than two detached accessory buildings are allowed per lot. Attached carports - those structurally tied to the house roofline - are reviewed as additions to the dwelling and must meet the principal-structure setbacks. Building permits are required for new carports, and HOA covenants in many Overland Park subdivisions impose additional restrictions on carports that are stricter than the UDO.
