A Private Pricing Opinion — what your apartment at The Yosemite 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.
550 Park Avenue — The Yosemite — is a 1917 J.E.R. Carpenter cooperative at the corner of Park Avenue and East 62nd Street, one of the early luxury apartment houses that established Park Avenue's identity as the city's premier residential avenue. Completed in December 1917, it stands among the avenue's pioneering full-luxury buildings, finished just as the Park Avenue apartment tradition was crystallizing into the form that would dominate the next two decades.
The Carpenter authorship is the point. J.E.R. Carpenter was the leading architect of Manhattan's golden-age luxury apartment houses — the figure most responsible for codifying the large, formally planned Park and Fifth Avenue residence that buyers still seek today. At 550 Park, that pedigree shows in the building's defining feature: an exceptionally low apartment count. With only around three dozen residences across 17 stories, The Yosemite is among the most exclusive buildings on the avenue by density, with large, gracious layouts and the rare intimacy of a building where neighbors number in the dozens, not the hundreds. It converted to cooperative ownership in 1952 and has a transfer history that should be reviewed by date before describing turnover; over the decades its residents have included August Belmont Jr., Diana Vreeland, and the building's own architect.
Architecture and unit composition
The roughly 4,400 square feet of building area per home is a gross-area ratio, not measured apartment living area or proof of a full-floor, simplex or duplex layout. Check the actual plans and dimensions for the specific residence. Carpenter's golden-age planning recurs throughout: ceiling heights reaching eleven feet in the primary rooms, formal entry galleries, separate dining rooms, libraries, herringbone walnut floors, oversized windows with varied exposures, and wood-burning fireplaces in many apartments. Private elevator landings serve many of the homes.
The corner siting at Park and 62nd delivers light and air on two sides, with Park Avenue exposures looking across the avenue's landscaped median. The combination of low density, large floor plates, and Carpenter detailing puts The Yosemite firmly in the connoisseur tier of pre-war Park Avenue cooperatives.
Building operations
The Yosemite operates as a white-glove full-service cooperative with a full-time doorman, attended elevator, a live-in superintendent, and private storage. Pets are allowed. Pied-à-terre use requires confirmation with the building. Financing is limited to 50% of the purchase price. A board-approval process applies; confirm the building's current liquidity, ownership and occupancy requirements from its application instructions.

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.

Market read. Most recent trades (2026 to date) cleared a median $1,279/sf (floor-adjusted) across 2 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 6.1% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
The small apartment count does not establish current availability; review actual listings and dated sales before setting expectations for a search. The Carpenter pedigree, the 1917 vintage, and the eleven-foot ceilings, galleries, libraries, and fireplaces are the real assets. Three policies matter to your strategy: pied-à-terre use requires confirmation with the building; a flip tax applies on a tiered or formula basis — confirm the payer and amount and build it into the all-in number from the outset; and financing is restricted to 50% of the price, so plan for substantial cash. Confirm the board's current liquidity and application requirements from its application instructions. We help buyers review current availability, evaluate the apartment, and prepare the board package.
What to know if you’re selling
Lead with exclusivity and pedigree: the very low unit count, the Carpenter authorship, the 1917 vintage, the eleven-foot ceilings and fireplaces, and the prime Park-and-62nd corner are the headline assets. The permitted pied-à-terre policy widens your buyer pool relative to many tier-one peers — a genuine marketing advantage worth foregrounding. With thin internal turnover, pricing draws on corridor-level golden-age Park Avenue precedent adjusted for the specific home. The buyer pool is narrow but deep; the right marketing reaches well-qualified buyers directly, and the closing follows the building's selective board process.

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.
