When is a building permit required?

The Commonwealth of Massachusetts State Building Code states that “it shall be unlawful to construct, reconstruct, alter, repair, remove or demolish a building or structure; or to change the use or occupancy or a building or structure; or to install or alter any equipment for which provision is made or the installation of which is regulated by 780 CMR (State Building Code) without first filing a written application with the building official and obtaining the required permit therefore.”
