Building Permit Information

The Purpose of a Permit

A Building Permit gives you, your insurance company, your neighbors and the Town assurance that specific minimum standards are met in constructing, altering, or repairing your home by complying with the Building Code.

These standards are based on well-established health, safety, and environmental considerations intended to protect the integrity of the buildings, safety of the inhabitants, and the welfare of the public.
