Description

The Opportunity 

21 Notre Dame Avenue presents an exceptionally rare opportunity to secure a 33,460 SF free-standing educational facility in the heart of Cambridge. Most recently operated as a charter elementary school, this expansive, multi-story building offers a blank canvas for a single-user educational, institutional, or municipal tenant. In a Cambridge market defined by severe inventory constraints for classroom and campus space, 21 Notre Dame provides the scale, location, and infrastructure to serve as a flagship private school campus, municipal swing space, or institutional training center.

Building Features & Infrastructure 

The property features traditional, high-ceiling classroom configurations, wide corridors, administrative offices, and a dedicated outdoor play/recreation space. Uniquely for Cambridge, the site includes access to approximately 50 +/- on-site parking spaces, providing unparalleled convenience for faculty, staff, and student drop-off/pick-up logistics.

Customization & Code Compliance 

The building is currently in "as-is" condition (non-sprinklered, limited-ADA compliant). Ownership is seeking a long-term, credit-grade single user and is highly flexible in structuring the transaction to accommodate necessary life-safety and accessibility upgrades. Ownership will consider providing an amortizing Tenant Improvement (TI) allowance to fund ADA compliance (including ramp/elevator installation) and sprinkler systems for a qualified tenant on a long-term lease, OR will offer highly aggressive, below-market base rent for an institutional user willing to execute their own capital improvements.

Location & Connectivity 

Situated in a vibrant, densely populated North Cambridge neighborhood, the property is immediately accessible to major thoroughfares (Route 2, Alewife Brook Parkway) and is walkable to the MBTA Red Line (Alewife and Davis Square stations). The surrounding demographics offer a deep pool of students, faculty, and professional staff.

Highlights

Size: 33,460 SF Free-Standing Educational Building
Parking: Rare 50 +/- On-Site Surface Spaces
Outdoor Space: On-site playground/recreation area
Condition: "As-Is" — Landlord will amortize TI allowance for ADA/Sprinkler upgrades, or offer below-market rent for tenant-funded improvements.
Ideal Uses: Public School Swing Space, Charter School Campus, Private/Parochial School, Special Education Collaborative, University/Institutional Trai
