Judge Temporarily Halts NYC Luxury Second Home Tax Rollout, Citing Flawed Implementation

A New York judge has temporarily paused the contentious implementation of Mayor Zohran Mamdani’s new tax targeting luxury second homes. On Monday, Judge Wayne Ozzi instructed City Hall to remove a publicly accessible list that included the names, addresses, and property valuations of over 900,000 New York City homeowners.

The judicial order temporarily restrains the Mamdani administration from proceeding with the surcharge based on the disputed property roll or any mailed notices. It also prohibits the city from enforcing upcoming deadlines against affected homeowners.

Furthermore, the signed order prevents the city from imposing, assessing, or collecting the surcharge from homeowners identified on the supplemental roll, or from sending further notices without first conducting individualized determinations and providing the required notifications under state tax law.

Judicial Intervention Halts Implementation

This courtroom setback follows sharp criticism from attorney Randy Mastro, who condemned the Mamdani administration’s handling of the surcharge, which applies to second homes valued at over $5 million.

“The city screwed this up… got it wrong… stop the train and make them do it over,” Mastro asserted in court.

Mastro contended that the city was obligated to ascertain whether properties genuinely qualified as non-primary residences before subjecting homeowners to the surcharge process. Instead, he argued, the administration published a supplemental property roll encompassing a vast number of properties and issued notices that compelled New Yorkers to scramble to prove their homes were, in fact, their primary residences.

“The city is to bear the burden,” Mastro stated, accusing officials of failing to utilize readily available information to determine eligible properties. “They didn’t do their homework.”

Mastro also highlighted that the publication of property owners’ names, addresses, and property values generated significant confusion and public outcry. He described the disclosure as effectively “doxx[ing]” homeowners, calling it “ludicrous” and “not right.”

Following the ruling, Mastro characterized the decision as “a very good day for all New York City homeowners.” He reiterated his view that the Mamdani administration “botched this rollout,” alleging that letters were sent to thousands of primary residents who “never should have received a letter suggesting they may be subject to the surcharge.” He also criticized the city for publishing a list of “over 900,000 New Yorkers by name, address and property value,” calling it a “pretty shocking thing that happened.”

Lawsuit Details and City's Defense

The lawsuit was initiated by three New York City homeowners who are not challenging the legality of the pied-à-terre surcharge itself, but rather the method of its implementation by Mamdani’s administration.

They allege that the city incorrectly identified their primary residences as potentially subject to the surcharge, failed to perform the statutorily required individualized initial determination before sending notices, and improperly shifted the responsibility onto homeowners to prove their exemption from the surcharge.

One of the plaintiffs, Simon Hedley, ultimately secured an exemption after submitting tax documentation. Mastro cited Hedley's experience as evidence of how easily the city could have made the necessary determinations itself. “Was it negligence, was it laziness?” Mastro questioned during the court proceedings.

The city, through attorney Steven Banks, defended its rollout, arguing that freezing the process would disadvantage taxpayers seeking exemptions and disrupt established deadlines. Banks maintained that preserving the supplemental roll would maintain the status quo and provide taxpayers sufficient time to navigate the process.

The hearing at times became contentious as legal counsel debated the administration’s management of the tax. When Mastro attempted to interrupt Banks during the city’s presentation, Banks retorted, “Say nothing while I’m speaking.”

The attorneys also clashed over Mastro’s description of the notices as “terrorizing” homeowners. Banks found the language offensive, referencing Mamdani’s status as the city’s first Muslim mayor. “That’s not terrorism,” Banks stated regarding the rollout, adding, “It happens to be acting in accordance with law.” Mastro later clarified that he was describing how homeowners perceived the notices, arguing that residents viewed them as threatening because they implied subjection to the surcharge.

Mastro consistently criticized the administration's execution of the tax, calling the situation “extraordinary,” the notices “bizarre,” and the publication of the property roll “ludicrous.” He emphasized that “thousands of New Yorkers are on edge” and urged the court to eliminate what he termed the “threat of jeopardy.” However, Banks countered, “A TRO radically upsets the status quo.”

Judge's Rationale and Administration's Resolve

In granting the temporary restraining order (TRO), Judge Ozzi determined that the notices had caused irreparable harm and that the city, not property owners, was responsible for making the initial determination. He also found that the plaintiffs were likely to succeed on the merits due to missteps by the city, while emphasizing that the underlying case has not yet been fully decided.

The judge acknowledged he could not “unring the bell” on notices already dispatched but could prevent further errors, stating that the city had not exercised due diligence.

Mamdani’s administration swiftly announced its intention to appeal the ruling.

“We disagree with today’s ruling, but we are confident in both the pied-à-terre surcharge and the City’s ability to implement it fairly and effectively,” stated Matt Rauschenbach, a spokesperson for the mayor.

Rauschenbach added that the surcharge aims to have owners of second homes valued at $5 million or more contribute their “fair share to the city they benefit from.” He indicated that the Law Department would “appeal the ruling immediately,” which the administration believes will stay the order, and that the city plans to continue implementing the surcharge.

Prior to the ruling, Mayor Mamdani had adopted a defiant tone, taking a jab at Mastro’s frequent legal challenges against City Hall. “There are few things more certain in New York City than death, taxes and Randy Mastro filing a lawsuit against this administration,” Mamdani remarked.

The mayor expressed confidence in both the legality of the city’s actions and the surcharge itself, arguing that revenue generated from second homes exceeding $5 million would help fund “safer streets,” “stronger schools,” and other essential city services.

When questioned directly about any regrets regarding the rollout, Mamdani defended the administration’s approach, while acknowledging that “with any new tax, there are more questions than there are answers.” He noted that only about 17,000 homeowners out of a city population of 8.5 million are potentially affected and highlighted the city’s extension of an exemption deadline.

Upcoming Legal Proceedings

The legal dispute is now progressing rapidly. Judge Ozzi has directed the defense to submit its order to show cause by August 24, with plaintiffs’ replies due by August 27. Oral arguments on the merits of the case are scheduled for August 31.
