144 East 84th Street is a solid, primary-residence Upper East Side cooperative on the corner of Lexington and 84th, at the edge of Carnegie Hill. Built in 1963 and converted to cooperative ownership in 1971, it is a well-run doorman building with a furnished rooftop terrace and — notably — no flip tax, at a price point below the prime Upper East Side avenues. It is the kind of building that anchors the neighborhood's owner-occupier residential base.
For buyers, the building's appeal is straightforward: a full-time-doorman cooperative in a convenient Upper East Side location, with a genuine outdoor amenity in the furnished roof terrace, and without the transfer-tax cost that most neighborhood co-ops impose. The corner-of-Lexington location places residents steps from the 4/5/6 trains at 86th Street, from Lexington and Third Avenue retail, and — for family buyers — near the Carnegie Hill private-school cluster covered in our Upper East Side corridor guide.
The tradeoff is that the building is oriented toward primary residents rather than investors or part-time owners: pied-à-terre use is not permitted, and subletting requires board approval. That orientation keeps the resident base owner-occupied and stable, which many buyers value. Like most Upper East Side cooperatives, the building prices in rooms rather than square feet.
Building operations
144 East 84th Street operates as a full-service cooperative with a 24-hour doorman, a live-in super, a central laundry, a bike room, common storage, and a furnished rooftop terrace. There is no garage and no fitness center — this is a service-and-location building with a roof amenity rather than a full amenity tower.
As a cooperative, the building reviews prospective purchasers through a board application and interview process. There is no flip tax, financing is permitted up to 70% (30% down), and subletting is permitted with board approval. Pied-à-terre use is not permitted — the building is oriented toward primary residents. Specific current policies, including pet policy detail, should be confirmed against building materials and the managing agent during due diligence. Our Co-op vs Condo guide covers the ownership-structure framing.

Facade safety — Local Law 11
The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. Facade inspections run on a fixed five-year cycle; future inspection, repair, and any assessment decisions remain building-specific.

144 East 84th trades at the Upper East Side's accessible cooperative tier, priced by room, with recent trading below the prime avenue cooperatives. The absence of a flip tax improves seller economics, and the furnished roof terrace and full-time service support demand at the tier, while the primary-residence orientation (no pied-à-terre, board-approved subletting) keeps the resident base stable. As with any cooperative, pricing should be read at the apartment level; room count, floor, exposure, and condition drive the variation.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01512-0052) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.
What to know if you’re buying
This is a primary-residence cooperative — priced by room, board-approved. Expect the cooperative purchase framework: a board application, a financial review, and an interview. The building is oriented toward owner-occupiers.
There is no flip tax. Most Upper East Side cooperatives impose a transfer tax at sale; 144 East 84th does not, which improves seller economics and can factor into buyer math.
Pied-à-terre use is not permitted. Buyers who want a part-time or investment apartment should look elsewhere; this building is for primary residents.
The furnished roof terrace is the building's outdoor amenity. For a cooperative at this tier, a furnished roof deck is a genuine draw.
Model the maintenance and the underlying mortgage. As a cooperative, the monthly maintenance covers the building's operating costs, property taxes, and any underlying mortgage. Review the building's financials and reserve position.
What to know if you’re selling
Foreground the no-flip-tax policy and the roof terrace. The absence of a transfer tax and the furnished roof deck are the building's principal selling points at the accessible Upper East Side cooperative tier. Pair them with the corner-of-Lexington convenience.
Pricing requires apartment-level comparable analysis. Recent comparables on the specific line, room count, floor, and exposure should anchor the approach.
Board approvability shapes the buyer pool. The primary-residence orientation and the board review mean the buyer pool skews to owner-occupiers; prepare buyers for the application and price to attract financially qualified applicants.
Closing timelines run to the cooperative calendar. Plan for a board application and interview cycle in addition to standard closing timelines.
