Building Permits
Cambridge, Massachusetts
April 26, 2026
Permit takeaway
Cambridge says anyone seeking to construct, alter, repair, or demolish a structure must first obtain a building permit, and ordinary repairs do not require a building permit.
Zoning and placement
Work must comply with the Cambridge Zoning Ordinance, and historic districts, neighborhood conservation districts, landmarks, preservation restrictions, demolition of structures over 50 years old, curb cuts, transportation conditions, and other departments can affect approval.
Building and trade review
Building permits are issued through Inspectional Services, and the permit card must be kept at the work site until the construction project is complete.
Call before applying when
Call before applying if the project changes structure, exterior appearance, zoning conditions, curb cuts, historic resources, or involves demolition or a sign.
