HERS Rating Dorchester, MA

HERS Rating Services in Dorchester, MA

HERS Rating Company provides certified HERS Index ratings across Dorchester, Boston’s largest and most diverse neighborhood and the heartland of the New England three-decker. Of the roughly 15,000 wood-framed triple-deckers built across Boston between 1880 and 1930, about a third rose in Dorchester. In climate zone 5A, these stacked three-family homes have distinct air-sealing and insulation needs that our RESNET-accredited raters know well, delivering fast, accurate ratings that keep projects compliant with Boston’s energy code.

Whether you are gut-rehabbing a 1900s three-decker near Fields Corner or building new infill housing along Dorchester Avenue, our certified HERS raters provide every document the City of Boston Inspectional Services Department requires for permits and final inspections.

Massachusetts Stretch Energy Code in Dorchester

Boston has adopted the Specialized Opt-in Stretch Energy Code (225 CMR Ch. 22), built on IECC 2021, requiring new construction and major renovations to be verified by a certified HERS rater. Dorchester projects must meet air-tightness targets confirmed by blower door testing and duct leakage testing — especially important in older wood-framed three-deckers with shared stairwells. We provide all documentation required by the City of Boston Inspectional Services Department.
