Description:

21 Notre Dame Avenue is a stand-alone condominium built for organizations that value presence, permanence, and access. Previously occupied by the Banneker Charter School, the property carries an established educational and community-serving legacy in a Cambridge location where independent facilities are tightly held. On-site parking is a practical advantage for employees, visitors, families, and program participants. The building’s free-standing configuration allows an owner-user to establish a visible identity and control its environment in a way that multi-tenant settings often cannot. Ideal for educational, nonprofit, religious, or related institutional use, the property places a long-term owner within reach of Cambridge neighborhoods, transit, universities, and Greater Boston’s innovation economy.

21 Notre Dame Avenue occupies a well-connected North Cambridge location shaped by residential density, public transit, and access to major regional routes. Route 2 and Alewife Brook Parkway are nearby, linking the property to Cambridge, Somerville, Arlington, Belmont, and Greater Boston. Davis and Alewife stations on the MBTA Red Line are approximately 0.7 miles from the property; Porter Square, approximately 0.9 miles away, offers both Red Line and Fitchburg/South Acton commuter rail service. That combination gives the address practical reach for employees, students, visitors, and families arriving from Cambridge and beyond. At the same time, the property remains embedded in an established neighborhood—a useful advantage for organizations that depend on visibility, community connection, and reliable everyday access. The location is well suited to educational, nonprofit, religious, and community-serving uses.
