515 Park Avenue: A Zeckendorf Condo Tower at 60th Street

515 Park Avenue is a 42-storey condominium tower completed in 2000 by the Zeckendorf family on the east side of Park Avenue at East 60th Street.

Its full-floor and duplex layouts, separately owned staff suites and condominium ownership shape the purchase as much as the Park Avenue address does. Here is what buying there involves.

1. What the Building Is

515 Park Avenue stands on the east side of Park Avenue at the corner of East 60th Street, on the block that runs south to East 59th Street. Completed in 2000, it was developed by the Zeckendorf General Partnership with the Whitehall Real Estate Fund and designed by Frank Williams & Associates.

Department of Buildings filings give the tower 42 storeys and a height of 529 feet, while it is marketed as having 43 floors. It replaced a pre-war building in the Italian Renaissance palazzo style, and its limestone, cast-stone and beige-brick facade steps back at the 15th, 33rd and 43rd floors.

The building is a condominium. The city's tax roll lists 57 residential units: 35 apartments from the fourth floor upward, many of them full floors or duplexes, and 22 small units on the second and third floors that listings describe as staff or guest apartments. Published apartment counts vary between sources, so confirm the current figure in the offering plan.

The location is on Google Maps.

2. A Zeckendorf Tower on Park Avenue

The tower was developed by the brothers William and Arthur Zeckendorf, and the Skyscraper Museum describes it as a real estate success. The museum showed a model of the building in its exhibition Sky High and the Logic of Luxury, as another project by the developer of 15 Central Park West.

Architecturally it is a Post-Modern design with traditional masonry, punched windows, cast-stone corners and double-height pilasters below each setback. Critics were not kind: Paul Goldberger found it particularly ungainly, and a 2006 architectural history records that it was deemed a poor addition to Park Avenue.

It should not be confused with 520 Park Avenue, a later and taller Zeckendorf tower designed by Robert A.M. Stern just off Park Avenue on East 60th Street. The two are separate condominiums, so check that any listing, sale record or document refers to 515.

Judge a specific apartment by its plan, light and outlook rather than by the facade debate.

3. Floor Plans, Staff Suites and Services

The tax roll shows how the tower is arranged. The fourth to eighth floors hold two apartments each, single apartments occupy whole floors from the ninth floor up, and from the 30th floor the homes are duplexes, ending with one on the 42nd and 43rd floors. Most owners above the eighth floor therefore have no neighbour on their own floor.

Below the apartments, the second and third floors hold small units used as staff and guest suites, and the basement holds private climate-controlled wine cellars and storage rooms. Each is a separate tax lot, so a listing may or may not include one, and it pays to confirm exactly what is being sold.

Building services include a full-time doorman, a concierge and 24-hour security, a fitness centre, a residents' library and a dining room off the lobby that can be used for catered events. The building allows pets, and there is no roof deck. Staffing and service hours are set by the condominium board through its annual budget.

Ask whether a staff suite, wine cellar or storage room is included in the sale, and on what terms.

4. Buying Here as an Overseas Purchaser

Because 515 Park Avenue is a condominium, there is no co-op board approval, and foreign buyers can purchase. Financing for foreign nationals is available from some lenders, but expect larger deposits and fuller documentation than a US borrower would face, so start the loan conversation early.

At closing the buyer pays New York's mansion tax on residential purchases of $1 million or more, charged on the whole price at graduated rates from 1% between $1 million and $2 million up to 3.9% at $25 million and above. On a later sale by a foreign owner, FIRPTA withholding of 15% of the gross price applies unless an IRS withholding certificate reduces it.

A non-resident who is not a US citizen has only a $60,000 US estate tax exemption on US-situs assets, so settle the ownership structure with tax counsel before contract. Since July 2026 New York City has also levied an annual pied-à-terre surcharge on high-value apartments that are not anyone's primary residence, and its administration is before the courts.

Settle structure and financing first, then make the offer.

Recorded Sales: What the Public Record Shows

NYC's Department of Finance records every sale with its address and price. Between January 2023 and September 2026 it recorded 10 sales of apartments at 515 Park Avenue, at a median price of $12.75 million. Half of them closed between $4.31 million and $15.88 million; the highest was $23.85 million.

A median across a whole building mixes small and large apartments, low floors and high ones, so it describes the building rather than any one residence. Use it to see how often apartments here change hands and where the building's prices sit. Price a specific apartment from recorded sales on the same line and floor range, which can be pulled from the deed records before you make an offer.

These are recorded deed prices, not asking prices, and none of them is a Reinvent NY transaction. A sale appears in the record weeks after closing, and a deed price can include a parking space or storage unit bought at the same time.

Final Thoughts: Full Floors at Park and 60th

515 Park Avenue combines condominium ownership with full-floor and duplex layouts, separately owned staff suites and a tower's height above Park Avenue. The trade-off is a facade that critics disliked and a location at the southern edge of the Upper East Side, on a lot the city zones within its Special Midtown District.

Read the latest financial statements and board minutes, and ask about the most recent facade inspection and any planned mechanical work on a tower completed in 2000. Those documents, not the address, determine what it costs to hold an apartment here and how the building funds its upkeep.

Price a specific apartment from recorded sales on the same line and floor range rather than from a building-wide average, because a lower-floor apartment shared with a neighbour and a duplex near the top are different products. Then weigh condominium flexibility against the co-op buildings nearby.

Request the offering plan and recent financials before you schedule a viewing.

Figures here describe the building, not any one apartment. Asking prices, monthly carrying costs, tax abatement status and sublet rules are established unit by unit from the offering plan, the most recent financial statement and the managing agent.
