740 Park Avenue, Manhattan

740 Park is one of the city's most prestigious co-ops, and its recent sales activity lives up to the legend.

This 33-unit pre-war building has a reputation as one of the most exclusive addresses in Manhattan. The public record shows a building that trades in eight-figure sums and is operationally very quiet. Three things to know:

Apartments here trade for massive prices, often to names you know. Two sales in the last year — $38M in April 2026 for 4/5D (the seller had paid $20.5M for it in 2019) and $14.99M in July 2025 to the Brodskys. Earlier in the cap stack: John Thain (ex-Merrill Lynch CEO) sold the PHD for $28M in 2023, and Steven Mnuchin's trust sold 8/9A for $22.5M in 2021. Howard Marks of Oaktree still holds the building's record — $52.5M for the combined 12/13 in 2012.

DOB's short-term-rental inspection unit has visited twice. Two complaints to SPIT — the city's Special Projects Inspection Team, which chases illegal Airbnb-style rentals — were filed in January 2020 and March 2022. Both were closed with no violation, so whatever the board was doing about it appears to have worked. But for a building this private, it's a rare window into something the co-op had to deal with internally.

Beyond that, the building barely shows up in city data. No open housing code violations. Roughly one 311 call a year over the last two — all closed, all minor (jackhammering on the street, a street-condition report, a water-conservation tip).

Quieter signals on this building and the blocks around it:

• On the second SPIT visit in March 2022, DOB's disposition reads: 'second attempt to conduct an inspection… was denied access. No further attempts will be made.' The city stopped knocking.
• A separate May 2022 complaint flagged 'illegal conversion of residential building/space' — closed with no further action, but it's a distinct beat from the short-term-rental tips.
• One lost-property report to 311 in June 2025. Descriptor: 'Other' — the city log doesn't capture what.
• Vendor-enforcement calls on the surrounding blocks run steady — 202 in the last 12 months. And Park Ave around 71st St sees regular encampment reports — 46 in the last year, most recent May 15, 2026. Street life a Park Ave resident hears about, not building events.
