Carports in Cambridge are accessory structures subject to zoning setbacks and a building permit over 120 sq ft. They are uncommon on dense lots and historic districts often restrict open-wall designs.
Under Cambridge zoning and the MA State Building Code 780 CMR, carports are treated as accessory structures. A building permit is required for any carport over 120 square feet, and zoning requires the carport to meet accessory-structure setbacks of typically 3 to 5 feet from side and rear lot lines. Because Cambridge lots are small and densely developed, carports are relatively uncommon compared to enclosed garages. Carports in Local Historic Districts or within the jurisdiction of the Cambridge Historical Commission are subject to design review that often disfavors freestanding open-wall structures on street-facing facades. Attached carports that reduce front-yard setback or alter the primary dwellings appearance may require a variance. Electrical and lighting work requires a separate electrical permit.
