NOTICE: Energy Code Effective Date Update:
The December 2019 Board of Building Regulations and Standards (BBRS) meeting included a discussion about the adoption of the 2018 International Energy Conservation Code (IECC) with Massachusetts amendments, which were expected to be effective January 1, 2020. Given the changes have been going through a lengthy review process that has not yet been completed, the new code will not be ready for implementation by the original deadline.  Since the BBRS intended the adoption process to include ample time to adjust to the new code, the BBRS has decided that users will be permitted to either utilize the existing energy code (based on the 2015 IECC) or follow the new energy code for a period of six months once the new code is approved and effective per the Secretary of State.

A public notice will be issued once an effective date for the new code is known. The BBRS will continue to monitor this process and will keep the matter as an item for possible discussion on its agendas until the new code is effective.

Due to vacation schedules in the building department (and the various other departments in town), time-frames for review and issuance of building permits may be delayed.  The building department regrets any inconvenience this may cause and will try to keep all applications under the 30 day allowance for review.

The mission of the Building Department is to protect the public by reviewing, approving and inspecting the built environment; to impartially enforce all rules, regulations and by-laws that pertain to both the State Building Codes and By-Laws of The Town of Westford; and to assist - to the best of our ability - all customers with any questions, concerns or complaints.
