Cambridge Massachusetts Building Permit Guide

Cambridge homeowners should check Inspectional Services before constructing, altering, repairing, demolishing, installing signs, changing licensed builders, or filing certificates of occupancy.

Permit takeaway

Cambridge states that anyone seeking to construct, alter, repair, or demolish a structure must first obtain a building permit, which must be posted at the job site.

Zoning and placement

Work must comply with Cambridge zoning, and properties in historic districts, neighborhood conservation districts, landmarks, or preservation restrictions may need Historical Commission approval.

Building and trade review

Building permits are generally issued to licensed construction supervisors, with an owner-occupant exception for certain one- or two-family dwellings.
