A federal judge has ruled that the developers behind 520 Park Avenue can keep Arte Moreno's $8.5 million deposit on a penthouse the former Los Angeles Angels owner walked away from days before closing back in 2019. The decision closes out a four-year legal saga that pitted the Zeckendorf family's development firm against Moreno and his wife, Carole, over a $34 million condo deal gone sour.
U.S. Southern District Judge Lorna Schofield, a federal judge for the Manhattan court, ruled that the noise the Morenos complained about from a neighboring mechanical room was not unreasonable and that the Zeckendorfs had taken all reasonable measures to manage it, according to The Real Deal. The Morenos had agreed in 2017 to buy penthouse PH-58 at 520 Park Avenue for $34 million, putting down the $8.5 million deposit before backing out days before the scheduled 2019 closing, citing noise concerns tied to an auxiliary pump and tank system.
A Four-Year Court Battle Over Mechanical Room Noise
The Zeckendorfs sued the Morenos for breach of contract in 2022, seeking $10 million in damages, while the Morenos countersued in 2023 demanding their $8.5 million deposit back. The dispute centered on whether noise from the equipment room infringed on the couple's quiet enjoyment of the unit, with the Morenos arguing the developers failed to take reasonable measures to mitigate the sound.
Back in November 2024, Judge Schofield denied summary judgment motions from both sides, ruling that the fight over whether the mechanical noise violated quiet-enjoyment provisions required a full trial, as detailed by The Real Deal. That one-day trial in 2025 featured testimony about acoustic levels and how often the main pump activated, with the Morenos' own acoustic expert describing the auxiliary pump's noise as somewhere between a whisper and a suburban area at night.
In the end, the judge sided with the developers, awarding the Zeckendorfs the full $8.5 million deposit plus interest and attorney fees. Attorneys Terrence Oved, Darren Oved and Aaron Solomon said the ruling completely vindicated their client's position, adding that a contract is a commitment, not an option, and that pretextual disputes to escape binding agreements will not be condoned.
A Building With a History of High-Stakes Litigation
Designed by Robert A.M. Stern Architects and completed in 2018, 520 Park Avenue is a 54-story, 781-foot limestone tower on the Upper East Side containing 33 to 35 high-end condominium residences, conceived by developers Arthur and William Lie Zeckendorf as a sister tower to 15 Central Park West. The building has drawn ultra-wealthy buyers including vacuum mogul James Dyson, who paid $73.8 million for a duplex penthouse in 2019, and investment banker Ken Moelis, who bought a 52nd-floor unit for $62 million in 2018.
The Moreno deal was not the building's only legal headache. Back in March 2019, Sotheby's International Realty sued the Zeckendorfs' development entity seeking between $945,000 and $1.8 million in unpaid commissions for introducing Moreno to the project in January 2017, though the developer's counsel called that suit baseless since Moreno never closed. Following the Morenos' exit, the Zeckendorfs resold the penthouse for $32 million, per The Real Deal's reporting.
More recently, private equity billionaire Orlando Bravo, who bought the building's trophy penthouse for $79 million, sued the Zeckendorfs in early 2025 alleging they failed to disclose a planned neighboring supertall that would block his Central Park views. That tower is Extell Development's 1,162-foot, 74-story project at 655 Madison Avenue, where crews began excavation in mid-2026, as Hoodline previously reported. Once finished, it will surpass 520 Park Avenue as the Upper East Side's tallest building.
Moreno's Angels Chapter Closes Alongside the Court Fight
The penthouse ruling lands just as Moreno wraps up a much larger transaction. Moreno agreed this month to sell the Los Angeles Angels to Stan Kroenke in a deal valued at roughly $4 billion, a striking jump from the $184 million he paid the Walt Disney Company for the then-Anaheim Angels in May 2003, when he became Major League Baseball's first Mexican-American majority owner, according to Forbes.
Moreno's 23-year run as owner included five AL West titles in the 2000s but was followed by an 11-year playoff drought, and the Angels lost 100 games for the first time in franchise history in 2026. Moreno also lost the chance to re-sign star Shohei Ohtani in 2023. Away from baseball, Moreno has stayed active in real estate, purchasing the 253-unit Cortland Biltmore apartment complex in Phoenix for $125 million in an all-cash deal in March 2026.
Zeckendorf Development, led by brothers Arthur and William Lie Zeckendorf, remains a fixture of Manhattan's luxury market, with a portfolio that also includes 18 Gramercy Park and 80 Clarkson. The penthouse ruling gives the family firm a clean legal win even as it continues to fight Bravo's separate lawsuit over the supertall next door.
