Mamdanis luxury-home tax rollout derailed for now as judge delivers win to NYC homeowners over massive list

A New York judge slammed the brakes Monday on Mayor Zohran Mamdanis controversial rollout of a new tax on luxury second homes, ordering City Hall to take down a controversial list exposing the names, addresses and property values of more than 900,000 New York City homeowners.

Judge Wayne Ozzi temporarily restrained the Mamdani administration from moving ahead based on the disputed property roll or mailed notices and barred the city from enforcing its looming deadlines against homeowners caught up in the rollout.

The signed order also prevents the city from imposing, assessing or collecting the surcharge against homeowners identified on the supplemental roll or sending a notice without first making the individualized determination and providing the notice required under state tax law.

The courtroom setback came after attorney Randy Mastro blasted the Mamdani administration over what he called a botched rollout of a surcharge targeting second homes valued at more than $5 million.

"The city screwed this up… got it wrong… stop the train and make them do it over," Mastro told the court.

Mastro argued that the city was supposed to first determine whether properties actually qualified as non-primary residences before putting homeowners through the surcharge process.

Instead, he said, the administration published a supplemental property roll covering a vast number of properties and sent notices that left New Yorkers scrambling to prove their homes were their primary residences.

"The city is to bear the burden," Mastro argued, accusing officials of failing to use available information to determine which properties actually qualified. "They didnt do their homework."

Mastro said the publication of property owners names, addresses and property values unleashed confusion and public backlash.

"This is ludicrous. It is not right," he told the court, arguing that the disclosure effectively "doxx[ed]" homeowners.

Outside the courthouse, Mastro declared the ruling "a very good day for all New York City homeowners."

"The Mamdani administration botched this rollout," Mastro said, alleging the city sent letters to thousands of people who live in their own homes and "never should have received a letter suggesting they may be subject to the surcharge."

He also accused the city of posting a list of "over 900,000 New Yorkers by name, address and property value."

"Thats a pretty shocking thing that happened," Mastro said.

The lawsuit was filed by three New York City homeowners who are not challenging the legality of the pied-à-terre surcharge itself, but rather how Mamdanis
