In 2017, the Society formally established a joint venture agreement with the Bronx Pro Group to build low-income senior housing at the former Trinity-Morrisania site on Washington Avenue. The Trinity-Rev. William M. James Affordable Senior Housing Complex was completed in 2021. There are 154 units for seniors who cannot afford to live in the city because of rising rents. This is a Section 8 rent-subsidized building. Over 50 units are designated for transitional housing for formerly homeless, justice-involved senior citizens. The Fortune Society, a NYC institution that works with returning citizens, has on-site services and a new satellite office in the building.
Located at 1074 Washington Avenue
 Amenities keep residents active, social, and healthy—the ground floor contains a community room, sunroom with a hydroponic garden, and gym. A large courtyard and terrace include exercise equipment, outdoor gardening, and other active and passive recreational spaces. The building is on the site of the former Trinity Morrisania Church, elements of which have been incorporated, including restored stained-glass windows and pews, documenting the property’s history.
