NEW YORK — New York City is taking aim at deceptive online apartment listings by forcing real estate agents and websites to clearly state when they use artificial intelligence.
Mayor Zohran Mamdani announced the new transparency mandate on Thursday as part of a sweeping package of tenant-protection policies. The rules target a rising fraudulent trend known in the real estate industry as “housefishing,” where landlords use technology to mask property defects.
Enforcement will fall on the Department of Consumer and Worker Protection, which will partner with major listing platforms like Zillow and StreetEasy to ensure compliance.
“You shouldn’t have to worry whether the apartment you are viewing online is real,” Mamdani stated during the announcement at the city’s Tenement Museum. Taking a direct swipe at one of the city’s most popular housing platforms, the mayor added, “It’s called StreetEasy, not StreetHard.”
The AI disclosure mandate emerged from a 68-page dossier detailing the administration’s recent “Rental Ripoff Hearings.” While a specific start date for the tech regulation remains unannounced, city officials confirmed the initiative will roll out as part of a staggered three-year implementation plan. New York follows California, which recently passed its own real estate AI disclosure laws.
StreetEasy quickly signaled its intent to cooperate with the city’s new regulatory framework.
“We agree with Mayor Mamdani that finding a new rental in NYC should be easy, and that’s why finding an apartment on StreetEasy is easy,” a StreetEasy spokesperson said in a statement. “We look forward to continuing our work with the Mamdani administration, as well as state and federal officials, to ensure it stays that way.”
The company added that it expects all listings to accurately represent homes “whether AI is involved or not,” and urged users to flag suspicious posts.
The legislative package extends far beyond digital deception to address physical housing quality. Mamdani announced universal inspections for heating complaints and a modernized scheduling system for renters.
“New Yorkers have been able to schedule food deliveries and the time they pick up their clothes at the dry cleaner for years,” Mamdani noted.
The administration is also launching targeted crackdowns on the city’s three most reported tenant grievances: pests, broken elevators, and toxic black mold. Landlords will face stricter penalties for cosmetic cover-ups of structural hazards.
“No longer will landlords be allowed to slap a new coat of paint over a wall of black mold and pretend that the issue is fixed,” Mamdani said.
To streamline code enforcement, the city will digitize its landlord penalty database to easily identify repeat offenders. The administration emphasized that the system is designed to isolate chronic violators while protecting law-abiding property owners.
“We know that not every landlord is a bad landlord, but we want to be able to find the ones that are,” said Cea Weaver, director of the Mayor’s Office to Protect Tenants.
The policy rollout delivers on core promises from Mamdani’s mayoral campaign, which heavily emphasized historic rental market reforms. Among these promises is a finalized rent freeze for eligible rent-stabilized apartments, which officially takes effect this coming October.
The city also plans to grant formal legal recognition to tenant unions to boost collective bargaining power against neglectful building management.
