The Cambridge Housing Authority (CHA) purchased 31-37 Mellen Street, a 26,000 square foot property, from Lesley University in late December 2025. Located in the Baldwin neighborhood between Harvard Square and Porter Square, the site is in close proximity to the area’s many amenities including local retail restaurants, and the MBTA train stations and bus transportation.

The CHA is planning to create new affordable housing on the sites under the provisions of the Affordable Housing Overlay (AHO).


The CHA purchased 31-37 Mellen Street from Lesley University in December 2025 with the support of the Cambridge Affordable Housing Trust.
