Construction Contractor Licensing in Massachusetts
The building code requires that construction of all one and two family dwellings of any size and all other types of buildings containing less than 35,000 cubic feet of enclosed space must be done under the supervision of a person licensed as a Construction Supervisor by the State Board of Building Regulations and Standards. The building code does not require a construction supervisor license for construction work on buildings other than one and two family dwellings that are more than 35,000 cubic feet, however, work on such buildings must be done under the control of an engineer or architect. Please note that many municipalities in Massachusetts. separate from the State requirements just noted, often require some type of contractor's licensing on these larger buildings. Please check with local municipalities directly for local contractor licensing requirements in addition to the State requirements.
