New York Landlords Will Have to Disclose AI-Altered Rental Listings Under Mamdani's "Rental Ripoff" Plan

New York City will require landlords to disclose when a rental listing has been altered using artificial intelligence, one of 23 policy actions in a new tenant-protection package that Mayor Zohran Mamdani released this week. The measures also move to legally recognize tenant unions and to escalate enforcement against what the city calls repeat-offender landlords.

The document, titled the Rental Ripoff Report, was built from testimony gathered at a series of Rental Ripoff Hearings held across the five boroughs. It ties directly to the housing crunch in New York City, where RentDataNow tracks a typical rent of roughly $4,049 a month, among the highest of any US city, a level that makes hidden fees and neglected repairs especially costly for renters.

What the 23-action report does

The centerpiece is a set of reforms aimed at shifting power toward tenants and modernizing how the city polices housing conditions. The report calls for recognizing tenant unions and expanding renters' ability to organize and bargain collectively over building conditions; requiring landlords to disclose when listings have been altered by AI or other digital tools; modernizing the city's building-owner registration and communication systems; and using the city's full enforcement authority, including inspections, enforcement programs, and litigation, against landlords who repeatedly violate the code.

The actions build on Mamdani's broader housing plan, Block by Block, which sets out to build 200,000 affordable homes, preserve another 200,000, and make what the administration describes as the largest investment in public housing in modern history.

What tenants told the city

Mamdani established the Rental Ripoff Hearings through Executive Order 8, signed in his first week in office. Between February and April, the administration held one hearing in each borough and took testimony online, engaging more than 2,400 New Yorkers.

The report catalogs the most common complaints. Pests showed up in 16% of the testimony, while mold and leaks each accounted for 13%. Beyond those, New Yorkers described chronic poor conditions, landlord harassment, confusing dealings with city agencies, deceptive fees, and surprise utility bills.

"At Rental Ripoff Hearings across the five boroughs, we heard from thousands of New Yorkers living with mold that was never treated, pests that were never addressed and fees that were never explained," said Mayor Mamdani. "From requiring disclosure of AI-altered listings to bringing our code enforcement systems into the 21st century and finally recognizing tenant unions, we are making it clear that every New Yorker deserves a safe home – and every landlord who refuses to provide one will be held accountable."

How the city plans to enforce it

The administration says it will use executive action, agency rulemaking, legislation, and litigation to carry out the recommendations. Among the executive and rulemaking steps: investigating every heat complaint individually rather than lumping together complaints from the same building, letting tenants schedule certain building inspections, speeding up responses to elevator-outage complaints, addressing the root causes of residential fires, and strengthening protections against harassment based on immigration status.

The Mayor's Office to Protect Tenants will also convene a Legislative Task Force to study deeper reforms to the housing-quality enforcement system. Ideas on the table include adding financial penalties for landlords who fail to remediate mold under the Underlying Conditions Program, strengthening the Alternative Enforcement Program for chronic violators, modernizing a property-registration process that is still paper-based and does not require owners to provide an email address, and letting the Department of Housing Preservation and Development serve violations through digital notice.

Fees, brokers, and the broader crackdown

The report also folds in the city's recent push on rental fees. The Department of Consumer and Worker Protection pointed to its enforcement of the FARE Act, which bars landlords from forcing renters to pay a broker fee when the landlord is the one who hired the broker. Council Member Pierina Sanchez, who chairs the Committee on Housing and Buildings, said her legislative priorities include modernizing property registration, strengthening enforcement, and holding repeat offenders accountable while supporting responsible owners in genuine financial distress.
