When I obtain my permit, how long do I have to start the work?

According to the Commonwealth's Building Code, "any permit issued shall be deemed abandoned and invalid unless the work authorized by it shall have been commenced within 6 months after its issuance; however, for cause, one or more extensions of time, for periods not exceeding 6 months each, may be granted in writing by the Building Commissioner or Inspector of Buildings." Extensions are normally granted without any trouble. However, if there have been changes to the Zoning By-Law or building code subsequent to the original issuance of the permit, any grandfather status may be lost if work has not begun (i.e., you will have to comply to the new requirements). Any requests for extension must be submitted in writing.
