New York Bans AI-Enabled Rent Price Fixing
New York Gov. Kathy Hochul signed a law banning landlords from using AI-enabled price-setting software, making New York the first U.S. state to outlaw algorithmic rent pricing after several city-level bans. The statute not only forbids using such tools to set rents or lease terms but treats landlords who do so as engaging in collusion—whether knowingly or with reckless disregard—creating a distinct antitrust violation. State officials point to an estimated $3.8 billion in additional tenant costs in 2024 tied to these algorithms and cite prior federal and investigative scrutiny of firms like RealPage. The law takes effect in 60 days, tightening state antitrust enforcement and aiming to curb algorithm-driven rent inflation during the housing affordability crisis.
