Mamdani urges NYC landlords to identify the AI used in their apartment images.

      The apartment featured in the StreetEasy photo is bright, spacious, and appears roomier than the actual dimensions suggest. Soon, under a proposal from New York City Mayor Zohran Mamdani, that listing will have to acknowledge the enhancements.

      On July 16, his administration released the Rental Ripoff Report, a 23-point agenda based on the testimonies of over 2,400 tenants. The most recent proposal would require landlords and brokers to reveal when listing images have been digitally modified, including AI edits—similar to the labeling used by platforms when they auto-label AI-generated videos.

      The enforcement of this requirement would be handled by the city’s Department of Consumer and Worker Protection, which will formulate the rules. The underlying principle is straightforward: edited images can make a property appear larger, brighter, or better maintained than it truly is, a gap that even watermarking tools aimed at detecting deepfakes struggle to remedy once an image circulates online.

      A related measure targets misleading rental advertisements directly, with the city indicating it will work alongside listing platforms such as StreetEasy and Zillow. Both initiatives address the growing disparity between the properties showcased online and the actual units prospective renters visit.

      While virtual staging is not a new concept, recent generative tools have made it almost instantaneous and difficult to identify: empty rooms can be furnished in moments, cracked ceilings can be concealed, and dim studios can be transformed into sunlit spaces. Renters often realize the disparity only during the viewing, if they are able to secure one, or after the lease has been signed.

      Mamdani, a democratic socialist who assumed office this year, has prioritized rental issues, particularly as AI continues to transform everything from listing images to property valuations. In June, the city's Rent Guidelines Board implemented a rent freeze on approximately one million stabilized apartments, a promise that was central to his campaign.

      The report emerged from five months of hearings across the city's five boroughs, where the highest number of complaints (16%) were related to pests, followed closely by mold and leaks. Overall, 2,419 individuals participated, including many who spoke at private sessions and others who shared their experiences online, detailing unexplained fees and unmet repair requests.

      Many of the 23 recommendations seem more focused on practical issues than on technology policy, covering items such as expedited housing court proceedings, recurring fines for serious violations, and formal recognition of tenant unions. One proposal even suggests testing smaller elevators in older buildings, while another aims to reassess credit checks and the “40 times the rent” income requirement that excludes many renters.

      “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,” Mamdani stated when releasing the report.

      His consumer-protection commissioner portrayed the AI provision as an extension of the powers the department currently employs to regulate the rental market, which includes this year’s ban on tenant-paid broker fees. However, landlord groups are not fully convinced. Real estate organizations claim that the rent freeze will lead to the deterioration of older buildings due to a lack of income, and some caution that an influx of new disclosure rules will increase costs and complications without addressing the supply issue. The administration argues that transparency in listings is the most cost-effective reform on the agenda.

      The AI provision comes amid broader concerns regarding how opaque software influences rental pricing and options, from algorithms purportedly driving rents up to location data used to manipulate prices in airfare and car rentals. The theory is that transparency is less expensive than monitoring every detail, and it’s easier to communicate to a public that has grown skeptical of overly flattering images.

      None of these proposals have become law yet. The consumer-protection regulations still need to be developed, and much of the broader agenda depends on the City Council or Albany, meaning that the warning label on your ideal apartment remains a proposal rather than a reality for now.
