Schaumburg, IL Accessory Structures: Carport Rules (2026)

Schaumburg requires a building permit for carport construction. Carports are considered accessory structures and must comply with all zoning requirements for the district. Placement is generally restricted to rear yards or side yards behind the front building line; front yard carports are typically not permitted to maintain neighborhood aesthetics. Setback requirements apply, typically at least 3 feet from side and rear property lines. Height is limited to one story. The carport's design and materials should be compatible with the principal dwelling. The structure must be engineered for northeastern Illinois wind and snow loads, as heavy snow accumulation can exceed 30 pounds per square foot. Footings must extend below the frost line (42 inches in the Chicago area) to prevent frost heaving. Open-sided carports (at least two sides unenclosed) are distinguished from enclosed garages for zoning purposes. The carport footprint counts toward the maximum lot coverage percentage. If the property already has a garage meeting the minimum parking requirement, the carport serves as supplemental covered parking. Metal, aluminum, wood, and fabric-covered carports each have different structural requirements.
