1648 & 1654 Massachusetts Avenue
In May 2026, the Cambridge Housing Authority (CHA) purchased two existing residential buildings located at 1648 & 1654 Massachusetts Avenue with financial support from the Cambridge Affordable Housing Trust (CAHT). The CHA will convert these properties to fully affordable housing as the existing market-rate units naturally turnover.
The buildings contain a total of 56,614 square feet, including 62 one-bedroom units and 17 two-bedroom units and two commercial spaces. The commercial spaces are located on the first floor of the 1654 Massachusetts Avenue building and are currently leased to Huron Cleaners and Marathon Sports.
Located between Harvard Square and Porter Square in Neighborhood Nine, the buildings are located in a prominent location with near access to local restaurants, shops, and public transit.
