Cambridge Inspectional Services says a building permit is required before constructing, altering, repairing, or demolishing a structure, while ordinary repairs as defined by the building code do not require one. The correct permit depends on the actual scope, so confirm the project with the city rather than relying on a directory category.
Use the Massachusetts Division of Occupational Licensure portal to check applicable trade licenses. For residential improvement work that falls within the state program, the MA Contractor Hub provides Home Improvement Contractor registration and history lookup.

Official requirements depend on the work and may change. These links are a starting point, not a determination that a listed provider holds a required credential.
Before the estimate
Confirm the business identity and current service area.
Check licenses and permits with the relevant state and city offices when the work requires them.
Request current insurance documentation and a written scope.
Compare estimates, warranty terms, schedule, and who will perform the work.
