The order demanded the administration stop publicly posting a Supplemental Roll detailing at least 900,000 property owners’ names, addresses, and property values. The TRO came down after a hearing in the August 7 lawsuit initiated by a group of NY homeowners against the City, Mayor Mamdani, the NY Department of Finance (NY DOF), and NY DOF Commissioner Richard Lee. The complaint also condemned other actions such as the City only using federal and state tax returns to make primary residence determinations. The pied-à-terre tax first appeared in the City’s 2026-27 budget which the NY State Legislature approved in May 2026. It was originally proposed by Governor Kathy Hochul to support Mayor Mamdani’s goal to decrease the NYC budget gap.
