New York's A 4991 would add Real Property Law § 222-a prohibiting a landlord, when setting rent for residential premises, from using or relying on an algorithmic device that uses, incorporates or was trained with nonpublic competitor data. A violation would be a deceptive act or practice under General Business Law § 349, with the remedies of GBL Article 22-A. Would take effect on the ninetieth day after becoming law and apply to rental agreements executed on or after then. Referred to Housing February 10, 2025 and January 7, 2026; it has not passed either chamber.
