About this home

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.
