Carport Rules: Brookline vs Weymouth

Can I build a carport in my Brookline front yard?

Not by right. Brookline's Zoning By-Law (Article V) and the Building Department's accessory-structure FAQ prohibit placing an accessory structure in any required front-yard setback. Within 75 feet of the street lot line a detached carport also cannot extend into the required side yard. Front-yard or street-belt placement is only possible with a Special Permit or Variance from the Board of Appeals under Section 5.43.

How close to my Brookline property line can a detached carport sit?

Under the Building Department's accessory-structure guidance and Article V of the Zoning By-Law, a detached carport (treated as an accessory building) must sit at least 6 feet from any side or rear lot line and at least 6 feet from the principal residence. Anything closer requires a Special Permit from the Board of Appeals. A building permit and certified plot plan are required from Inspectional Services (617-730-2100).

Can I build a carport in my side yard in Weymouth?

Yes, in most cases. Weymouth Code § 120-54 specifically exempts private garages and carports from the general rule confining accessory uses to the rear yard. A carport may be placed in a side yard provided it meets the side-yard setback for the underlying residence district under Article XV of Chapter 120 - one-story carports with a permit may sit no closer than five feet from a side lot line. Carports may not be placed in the required front yard.

Do I need a permit to build a carport in Weymouth?

Yes for almost all carports. 780 CMR §R105.2 exempts one-story detached accessory structures of 200 square feet or less, but a typical carport sized to fit a vehicle exceeds that, and any carport attached to the dwelling is part of the principal structure. The Weymouth Department of Municipal Licenses and Inspections issues the building, electrical, and structural permits, and zoning compliance with Chapter 120 must be confirmed first.
