NYC Homeowners Sue Over 900,000-Name Tax Roll as Mamdani Defends Pied-à-Terre Surcharge

Summary
Three New York City homeowners sued Mayor Zohran Mamdani and the finance director, seeking to void notices tied to the new pied-à-terre tax and force the immediate removal of a public property list.
The suit says the city wrongly flagged primary residences as possible second homes and published names and addresses for more than 900,000 homeowners, even though most listed properties were not subject to the surcharge.
About 17,000 owners received letters telling them they might owe the tax unless they proved a home was their primary residence; plaintiffs also want that response requirement and any enforcement paused during the case.
The surcharge applies to non-primary residences in New York City valued above $5 million, and to co-ops worth $1 million or more, as part of Mamdani’s 2027 budget plan to help close a fiscal gap.
Backlash over the online list had already pushed Mamdani to extend the compliance deadline by four weeks to Sept. 18, while City Hall says it will vigorously defend the rollout.
