Massachusetts Stretch Energy Code in Charlestown

As part of the City of Boston, Charlestown falls under the Specialized Opt-in Stretch Energy Code — Massachusetts’ most demanding tier, built on IECC 2021 (climate zone 5A) with state amendments under 225 CMR Ch. 22. New residential construction must be verified by a certified HERS rater, with envelope air-tightness confirmed by blower door testing and ductwork verified by duct leakage testing — requirements that are especially exacting in Charlestown’s older, attached housing stock. We prepare and submit all documentation required by the City of Boston Inspectional Services Department.
