49 Sixth Street_Former Church and Convent

Preservation of Affordable Housing (POAH), a Boston-based nonprofit, is converting a portion of the Sacred Heart property in East Cambridge into affordable rental housing. The Sacred Heart property currently consists of a school building, convent, rectory, chapel, and church facility. The plan calls for the adaptive reuse of the former convent, school, and rectory buildings into 46 affordable rental apartments, with housing options for a range of resident incomes. As part of the renovation, POAH is restoring the structures’ historic facades and interiors. The church and the chapel will continue to be used by the Archdiocese.

The project is permitted under the provisions of the Affordable Housing Overlay (AHO).


In June 2025, POAH closed on all financing needed for their 49 Sixth Street development after many months of preparation. The construction of 46 new affordable rental housing units in the East cambridge neighborhood is underway with anticipated completion by the fall of 2027.
