About This Property
Opportunities to purchase at 85 Fifth Avenue are exceptionally rare—so rare, in fact, that this marks the first office sale in the building in more than 10 years.
Positioned along one of Manhattan’s most iconic corridors, at the intersection of Union Square, Flatiron, and Greenwich Village, 85 Fifth Avenue offers buyers a chance to secure long-term ownership in a tightly held cooperative where supply is virtually nonexistent.
The available space benefits from strong natural light, efficient proportions, and flexible layouts ideal for owner-users, professional firms, or investors seeking stability in a premier Fifth Avenue location. The building’s classic prewar architecture conveys permanence and credibility, while modern systems support today’s office needs. The building is completely electric, will not be subject to any NYC Local Law 97 carbon emission fines in 2030, and boasts an Energy Efficiency Grade of 97.
Some space highlights include brand new electric baseboard heating, 3 Zone HVAC, 5 private bathrooms, 11 ½ foot ceilings and lots of oversized windows bringing in great natural light.
With leasing costs continuing to fluctuate and quality inventory shrinking, ownership at 85 Fifth Avenue provides control, predictability, and insulation from market volatility—advantages that have clearly motivated existing shareholders to hold for decades.
This offering represents a once-in-a-generation opportunity to establish a lasting presence on Fifth Avenue in a building where ownership rarely changes hands.
Perfect for an owner/user or an investor, as the space can be easily reconfigured or subdivided to meet your needs.
The ground floor retail is anchored by the recently opened New York Flagship Nespresso Experience Store.

RE Tax/CAM is $18,040 Per Month
Agent's Note
From Curtis Bain. Details about the apartment are drawn from the listing information provided through RLS by Compass.
This 9,300-square-foot space is offered with a flexible layout, and five private bathrooms are part of how it can divide. The listing describes it as easy to reconfigure or subdivide, which matters for an owner-user or a firm that needs to plan its own rooms. I like that the proportions are efficient, and the 11 ½ foot ceilings and oversized windows give the rooms height and strong natural light.
Heating is brand new electric baseboard, supported by 3 zone HVAC. The building is completely electric and carries an Energy Efficiency Grade of 97, which is a useful number to have in hand when you're comparing operating systems.
The building dates to 1901 and sits within the Ladies' Mile Historic District. For buyers who want defined rooms and classic prewar detail, that history is a real part of the appeal. An elevator serves the building, which helps with moving furniture and equipment into a space this size.
Union Square Park is about three minutes away on foot, and the 14 St-Union Sq station, served by the 4, 5, 6, L, N, Q, R and W trains, is about four minutes. Because this is a co-op, the purchase runs through the building's board, and an attorney is the right person to walk you through those steps.
