Who Cooper Square Realty was
Cooper Square Realty was a New York City residential property manager founded by David Kuperberg with the stated aim of professionalizing the city's residential-management business. It became a subsidiary of FirstService Residential in 2003 and, per its own materials, grew into one of the largest residential managers in the New York City area.
On June 27, 2013, Cooper Square Realty was renamed FirstService Residential, part of a coordinated rebranding in which numerous regional FirstService subsidiaries adopted a single unified name. At the time, the firm's leadership described the change as a name change only, with ownership, local leadership, operations, personnel, and services remaining in place. Kuperberg became president of FirstService Residential New York.
For a buyer or seller today, the practical takeaways are simple:
- The Cooper Square Realty name is retired. You will not contract with, or receive documents from, a firm operating under that name in current transactions.
- The successor is FirstService Residential. A building historically managed by Cooper Square Realty is, in the ordinary case, now managed by FirstService Residential — subject to the building having since changed agents, which does happen.
- Verify the current agent, not the legacy name. Older offering plans, board minutes, or building records may still reference "Cooper Square Realty." That is a historical reference and should be reconciled against the building's current managing agent.
Common diligence questions
These are the questions we ask on a buyer's or seller's behalf when a building's records reference Cooper Square Realty. They are prompts for diligence, not claims about the firm's practices — answers vary by building and change over time.
- Current agent of record: Is the building now managed by FirstService Residential (the successor to Cooper Square Realty), or has it since moved to a different managing agent entirely?
- Legacy-name references: Where do offering plans, amendments, or board minutes still say "Cooper Square Realty," and how should those be read against the current managing agent and contracting entity?
- Access to financials, reserves, and minutes: What financial statements, current budget, reserve position, and board-meeting minutes will the current managing agent release to a purchaser's attorney, and how quickly?
- Board-package turnaround: How long is the current agent taking to review a completed purchase application and schedule a board interview, and what is the realistic window to a closing-ready approval?
- Closing, waiver, and move-in handling: How does the current agent process the recognition/waiver of the right of first refusal (co-op) or the waiver of the right of first refusal (condo), closing scheduling, and move-in coordination?
- Assessments and capital projects: Are any current or anticipated capital assessments, Local Law 11/facade, elevator, or mechanical projects on the books, and how are they being funded?
Buying or selling in a building formerly managed by Cooper Square Realty?
We publish management-company profiles because the managing agent shapes the parts of a transaction a buyer or seller actually feels — how fast a board package moves, what the financials disclose, and how a closing gets scheduled. The Roebling Team at Compass tracks Manhattan's co-op and condo inventory building by building and brings that context to every deal.
