Massachusetts H1004 aims to enhance building codes to better withstand climate change impacts.

Massachusetts H1004 introduces amendments to state building codes to incorporate climate resilience standards. The bill mandates the adoption of expanded floodplain maps, which include forward-looking climate data, for use in determining base flood elevation and flood-resistant construction requirements. It establishes a climate resilience retrofit program to assist in bringing existing buildings into compliance with new standards, prioritizing those in environmental justice areas and flood hazard zones.
