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.
