The lawsuit, which has ties to a Republican city council member and Mamdani’s past rivals, accuses the city of ignoring state law

3 NYC homeowners said their primary residences were included in a list of property records tied to the rollout of the new tax.

A group of New York City homeowners sued Mayor Zohran Mamdani and the city’s finance director over the rollout of the new pied-à-terre tax Friday.

New York City Mayor Zohran Mamdani's pied-à-terre tax was temporarily blocked by a judge after homeowners sued the city.

Plaintiffs said that Mamdani incorrectly identified their primary residences as possibly subject to the new tax, among other issues.
