Northeastern University has purchased 320 Huntington Ave. from the Greater Boston YMCA and signed a 20-year lease, allowing 67 units of transitional housing to continue to operate in the Hastings Wing of the building.

The Hastings Wing houses the Cardinal Medeiros Program, which has been assisting people transitioning from homelessness to permanent housing for 20 years.

The Massachusetts Housing and Shelter Alliance (MHSA), the program’s sponsor, in partnership with the Kit Clark Senior Services Cardinal Medeiros Program, the Massachusetts Department of Housing and Community Development, and the city of Boston, signed a lease agreement with Northeastern University to continue operations of the program.

"I applaud Northeastern University for working with us to preserve 67 units of transitional housing in Boston’s Fenway neighborhood," Boston Mayor Thomas M. Menino said in a statement. "I am pleased that the 20-year lease will allow Cardinal Medeiros Program to continue to provide services to the some of our most vulnerable citizens."

The partnership furthers the city’s plan to end homelessness by preserving housing opportunities in Boston, while also recognizing the need for Northeastern University’s continued growth. The new collaboration between the university and MHSA addresses housing and homelessness in Boston’s Fenway neighborhood.

"MHSA is pleased to have the strong support from the Mayor’s office as we work together to address homelessness in Boston," MHSA’s President and Executive Director Joe Finn said in a statement. "We welcome this new partnership with Northeastern University and look forward to continuing to provide these critical services in the Hastings Wing."

Northeastern President Joseph Aoun thanked the mayor for his "support and guidance."

"At Northeastern, partnering with the community and our neighbors is part of our character as an institution," Aoun said in a statement.
