Carports in Boston need an ISD building permit if attached to the home or over 200 sq ft. Side and rear setbacks follow the underlying zoning district and historic district rules.
A carport is a roofed, open-sided structure for vehicle storage. Boston treats carports as accessory structures under Article 23 of the Zoning Code. A detached carport under 200 sq ft and not attached to the dwelling may be exempt from building permit, but Boston dense-urban setbacks (typically 3 to 5 feet side, 10 feet rear in R districts) still apply. Attached carports need a full building permit and must conform to the main building setbacks. Historic districts (Beacon Hill, Back Bay, South End Landmark) often deny new carports as out of character. Shared driveway or alley access may require a cross-easement recorded at Suffolk Registry of Deeds.
