Orland Park, IL Accessory Structures: Carport Rules (2026)

A carport is a roofed structure open on at least two sides intended to shelter a vehicle. Orland Park requires a building permit to construct a carport, whether attached to the home or detached. Attached carports must meet principal structure setbacks (typically larger front, side, and rear setbacks) because they are considered part of the main building under the zoning code. Detached carports in the rear yard follow accessory structure setbacks (typically 3 to 5 feet from side and rear property lines). Maximum height is typically that of accessory structures. Materials must be suitable for permanent construction; fabric, canvas, or membrane portable 'carports' are generally not recognized as compliant carports and are often treated as temporary structures or, if kept year-round, as property maintenance issues. Roof runoff must be directed to the property's drainage system and not onto neighboring lots. Carports may count toward lot coverage limits. HOA subdivisions throughout Orland Park typically prohibit carports outright through architectural covenants, requiring fully enclosed garages instead.
