New York City Mayor Zohran Mamdani, who was sworn in at midnight and again publicly several hours later, used his first full day in office on Thursday to issue new executive orders focused on landlords and housing development. Mamdani said the city would also pursue what he described as “precedent-setting action” to intervene in a private landlord bankruptcy case that he said involves 93 buildings across New York City.

“Today is the start of a new era for New York City,” Mamdani said. “It is inauguration day. It is also the day that the rent is due.”

Speaking at an apartment building in Brooklyn, Zohran Mamdani described the actions as an early test of whether city government will directly challenge landlords over housing conditions and intervene in legal proceedings that could affect whether tenants are able to remain in their homes.

Mamdani said residents who attended his inauguration were returning to apartments where, he argued, landlords fail to make necessary repairs, rents continue to rise, and tenants face ongoing problems such as infestations and inadequate heat. He said his administration “will not wait to deliver action” and “will stand up on behalf of the tenants of this city.”
