Judge halts Mamdani's pied-à-terre tax notices

Judge halts Mamdani administration’s pied-à-terre tax rollout

A Staten Island judge has ordered Mayor Zohran Mamdani’s administration to redo its rollout of the new pied-à-terre tax on luxury second homes, invalidating over 17,000 notices sent to property owners and requiring the city to disclose the evidence used in determining which properties qualify as non-primary residences. Judge Wayne Ozzi’s decision follows a lawsuit from property owners who argued the city created “mass confusion” by publishing a list of nearly one million potentially affected addresses, with improper burdens placed on homeowners to prove their residency or risk being subjected to a new surcharge.

The conflict deepened as billionaire Stephen Wynn and former Trump Commerce Secretary Wilbur Ross filed a separate constitutional challenge against the tax, which targets homes valued at $5 million or more, or condos and co-ops worth at least $1 million, primarily affecting nonresident owners. Central to both cases are questions about whether the city’s process complied with state law and whether discriminating against nonresidents is permissible. The legal pathway is driven by recent state enforcement requirements and increasing scrutiny of how the Mamdani administration used housing data to identify affected properties. Insiders note that former deputy mayor Randy Mastro, representing plaintiffs, claims that these actions violate existing homeowner protections and due process standards.

What is settled: the city must develop and send new, legally compliant tax notices, and it must reveal the records underlying its determinations, pending an appeal. What is contested: the ongoing challenge in Suffolk County, which may impact the tax’s legality for all nonresidents, and how the city handles disclosures and burdens of proof. The next concrete step is the city’s appeal of Judge Ozzi’s order and preparation of new notices to owners identified as holding non-primary residences. The court’s disclosure requirement and appeal outcome will determine whether the surcharge can proceed this fiscal year.

The HOUSE VIEW: The Mamdani administration must reveal its selection criteria and resend notices before any pied-à-terre surcharge collections can begin.
