A Private Pricing Opinion — what your apartment at The Mayfair 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.
610 Park Avenue occupies a unique place in the Lenox Hill residential market: a 1925 J.E.R. Carpenter hotel building, on a corner site one block east of Central Park, converted to condominium ownership in 1997–1998. The conversion was led by a joint venture of Colony Capital and the Trump Organization, which acquired the building out of bankruptcy for approximately $15 million and invested roughly $55 million in the gut renovation. Costas Kondylis & Partners reconfigured the former hotel rooms into 68 condominium apartments; Mac II handled the common interiors.
The building's identity carries two distinct architectural pedigrees in a single envelope. The exterior is Carpenter's 1925 design — brown brick over a three-story limestone base, the Park Avenue residential idiom Carpenter helped to define across the corridor's pre-war construction cycle. The interiors are the late-1990s conversion, calibrated to contemporary luxury condominium specifications. The result is one of the few conversions on Park Avenue that pairs pre-war architectural fabric with contemporary condominium ownership mechanics — and one of very few Park Avenue condominiums of any vintage between East 60th and East 79th Streets.
The building's ground floor houses Restaurant Daniel — Daniel Boulud's flagship restaurant, which opened in 1998 in the space previously occupied by Le Cirque (Sirio Maccioni's restaurant operated there 1974–1997). The Daniel presence adds an institutional cultural amenity uncommon among Manhattan residential buildings.
Architecture and unit composition
The 68 residences distribute across the building's 15 stories in configurations ranging from one-bedroom apartments through full-floor and combined penthouses. The conversion preserved Carpenter's exterior fabric and produced interiors specified to the late-1990s luxury condominium tier — generous ceiling heights, formal entry galleries, and apartment layouts more reminiscent of pre-war Park Avenue cooperatives than of conventional condominium construction.
Building operations
610 Park operates as a full-service condominium with 24-hour doorman, concierge, valet parking, fitness center, and live-in resident manager. Daniel's catering services are available to residents — a hospitality-adjacent service register specific to the building's restaurant tenancy. The building does not have a roof deck, balconies, or an on-site garage; valet parking is offered.
The Trump Organization presents the property within its luxury portfolio, suggesting continued management or equity involvement.

Sublet and pied-à-terre policy
A condominium owner leasing a unit and a co-op shareholder subletting are different rules, and a building-wide rule is different from a restriction on one apartment. This is the building's rule; confirm it for the specific apartment.

Common charges plus real estate taxes, combined into one monthly figure the way New York condominium listings show them. Add a mortgage payment for the monthly outlay. The split into common charges and taxes comes from the listings that also give the annual tax, a different sample, so the two lines need not add up exactly to the combined median; a tax abatement can hold taxes below the full amount until it expires. A summary of recorded sales and listings, not a current bill; charges change.

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.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — the licensed engineer the city requires to sign the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2025–30. 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 $2,407/sf (floor-adjusted) across 1 sale. 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
Condominium mechanics on a Carpenter-designed Park Avenue building is structurally rare. Most Park Avenue residential between East 60th and East 79th Streets is cooperative. The condominium form supports pied-à-terre buyers, LLC and trust ownership, foreign buyers, and the broader transactional flexibility that condominium ownership permits — none of which are typically available at peer Park Avenue cooperatives.
The Restaurant Daniel ground-floor tenancy is an asset and a feature. Buyers should weigh both — the institutional address association is real, and the in-building access to one of New York's defining French restaurants is a daily-life amenity.
Carpenter's 1925 exterior is protected. The Upper East Side Historic District designation governs exterior modifications; interior renovations follow condominium board protocols.
Verify management and policy specifics during due diligence. The Trump Organization's continued role in management or equity should be confirmed; offering plan policies on subletting, pet rules, and any flip tax structure should be reviewed.
What to know if you’re selling
Marketing should anchor on the J.E.R. Carpenter pedigree and the condominium form. Both are real and structural; the combination is uncommon in the Lenox Hill market and supports premium positioning relative to peer condominium inventory.
The Restaurant Daniel association is a real marketing asset. It distinguishes the building from peer condominium inventory and from the surrounding cooperative tier.
Pricing requires apartment-level comparable analysis. The combined-unit and penthouse inventory at the building carries substantially different pricing than the standard floor inventory; recent comparables should anchor positioning.

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.
