When is a Building Permit required?

The Massachusetts State Building Code 780 CMR states that "it shall be unlawful to construct, reconstruct, alter, repair, remove or demolish a structure; or to change the use or occupancy of a building or structure; or to install or alter any equipment for which provision is made or the installation of which is regulated by this code" without first obtaining a building permit. This includes, but is not limited to new:

  • Additions
  • Antennae
  • Chimneys
  • Decks
  • Dormers
  • Roofing
  • Sheds
  • Siding
  • Structures
  • Swimming pools
  • Woodstoves

The only exception is an ordinary repair. An ordinary repair does not require a building permit.
