A New York State Supreme Court judge has temporarily blocked the rollout of New York City’s new tax on second homes.
The ruling halts a key revenue and housing policy championed by Mayor Zohran Mamdani (D), raising questions about the city's ability to implement high-value property taxes without violating procedural safeguards.
Judge Wayne Ozzi said in the decision on Monday, Aug. 5, that the city mishandled the rollout of the "pied-à-terre" tax [1, 2]. The tax specifically targets second homes valued at more than $5 million [3].
According to the court, the city failed to follow proper procedures when it compiled and published a public list of more than 900,000 homes that could be subject to the tax [3]. The judge ordered the city to remove this list from public view immediately.
Further complications arose from the city's direct communication with property owners. The court found that the city sent letters to roughly 17,000 owners without sufficient procedural protections [4]. Judge Ozzi barred the city from taking further action based on those letters.
While the judge blocked the current rollout, the city has moved to appeal the decision [4]. This legal move may allow the city to proceed with certain aspects of the plan while the court considers the appeal [4].
Estimates on the scope of the tax vary. Some reports indicate that approximately one million New York City residents own second homes that could be affected by the measure [5]. The city's public list, however, focused on a slightly smaller group of 900,000-plus properties [3].
The case was heard in Staten Island, where the court determined that the administration's lack of safeguards outweighed the immediate goal of tax collection.
“Judge Wayne Ozzi has temporarily blocked the rollout of New York City’s new tax on second homes.”
This ruling highlights the tension between aggressive municipal revenue generation and due process. By flagging the public listing of nearly a million homes and the notification of 17,000 owners as procedural failures, the court is signaling that the city cannot bypass transparency and privacy safeguards in its pursuit of taxing high-net-worth individuals. The outcome of the city's appeal will determine if the 'pied-à-terre' tax remains a viable tool for Mayor Mamdani's administration.
