A Private Pricing Opinion — what your apartment at 951 Park Avenue would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
951 Park Avenue belongs to the first great wave of Park Avenue apartment construction — the years right around 1915 when the avenue was transformed from a railroad cut into the most prestigious residential boulevard in America. It was designed by Robert T. Lyons, an architect closely associated with the Bing & Bing development office, whose pre-war apartment houses set the standard for solidly built, well-planned middle-and-upper-tier Manhattan living. Lyons's hand is on several of the avenue's early cooperatives, and 951 is cut from the same cloth: a thirteen-story masonry building, dignified rather than showy, planned for spacious family apartments.
What gives the building its particular character today is its ownership. 951 Park is held by a tenant-stockholder cooperative corporation — it is owned by its residents, not a landlord — and it sits squarely inside the Park Avenue Historic District, the protective designation that has kept this stretch of the avenue architecturally intact. For buyers, that combination is the appeal: a true pre-war co-op, on Park Avenue, in a landmarked corridor, at a scale and price point more attainable than the avenue's largest trophy houses.
Architecture and unit composition
Lyons designed 951 in a restrained Colonial Revival idiom, the Landmarks Preservation Commission's classification for the building — red brick with limestone and a classical crowning cornice, with a small amount of ground-floor commercial space. Thirteen stories and 28 apartments give a building-wide ratio, not a floor-by-floor schedule or measured interior sizes. Verify the actual apartment’s foyer, dining room, ceiling heights and surviving plasterwork against its plans and condition.
Building operations
951 Park is run as a full-service pre-war cooperative for its resident-owners. The lobby is attended, a live-in resident manager oversees the building, and storage is available. As a cooperative inside the Park Avenue Historic District, the building is governed by a residential board that reviews purchasers through the customary board package and interview, and exterior and visible alterations are subject to Landmarks review. The documented terms are 50% maximum financing, a 2% seller-paid flip tax, and no subletting or pied-à-terre use. We help buyers confirm the building's current financing parameters, flip-tax structure, and sublet posture against the cooperative's governing documents before they bid.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

What to know if you’re buying
Buying at 951 Park means buying into a resident-owned pre-war co-op on a landmarked block of Park Avenue. Expect a full board-package process with financing and reserve review; the documented terms are 50% maximum financing and no subletting or pied-à-terre use. The upside is a genuine Park Avenue address with real pre-war scale and detail, in a corridor protected from over-development. We help buyers read the financials, gauge the board's posture, and benchmark pricing against the avenue's comparable small co-ops.
What to know if you’re selling
The address and the architecture do much of the work. A Park Avenue cooperative, in the Historic District, with Lyons / Bing & Bing pedigree and intact pre-war layouts, appeals to a specific, motivated buyer. Establish turnover from dated qualifying sales and compare the actual apartment with matched Park Avenue alternatives. Present surviving period detail accurately; the unit count and address do not establish holding periods or a durable price premium.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
