Nearly 900,000 New York City homeowners woke up last week to find their names, home addresses, and property values dumped into a public database — courtesy of Mayor Zohran Mamdani's office. Seventeen thousand of them also got tax notices in the mail. The city didn't bother to check whether most of them actually owed anything.
On August 10th, Staten Island Supreme Court Justice Wayne Ozzi told the mayor's office to knock it off.
Justice Ozzi issued a temporary restraining order blocking enforcement of Mamdani's "pied-à-terre" surcharge — a tax on luxury second homes valued above $5 million that somehow managed to sweep up ordinary homeowners who don't own a second mailbox, let alone a second mansion. The court barred the city from imposing, assessing, or collecting the surcharge and ordered the published database of homeowner information taken down. Another hearing is scheduled for the end of the month.
The lawsuit was brought by homeowners Rachel O'Brien, Carmine Morano, and Simon Hedley — Hedley being a self-declared Mamdani supporter, which tells you something about how badly the city botched this. Their attorney, Randy Mastro, didn't mince words outside the courthouse.
"The city screwed this up… got it wrong… stop the train and make them do it over," Mastro said. He called the city's approach "ludicrous" and added that under state tax law, the city bears the burden of making individualized determinations before sending out notices — something it apparently skipped entirely.
"A very good day for all New York City homeowners," Mastro said after the ruling.
Mamdani, for his part, had been strutting around with the confidence of a man who'd never read the state tax code. Days earlier he'd taunted homeowners at an event: "Check your mailbox when you're back in the five boroughs, because you've got mail."
What makes this one worse is the data dump. Publishing 900,000 homeowners' personal information and property values on a public database isn't a policy tool. It's a pressure campaign. It's designed to make people feel exposed so they'll pay up rather than fight. That three of those homeowners lawyered up inside a week suggests the strategy backfired.
The TRO is temporary. The end-of-month hearing will determine whether the injunction becomes permanent. But the ruling already establishes the core problem: the city sent 17,000 tax notices without doing the individual assessments the law requires.
Turns out "tax the rich" works better as a bumper sticker than as a legal theory.
