Legislative declaration

Legislative declaration. The legislature finds that the use of algorithmic devicesAlgorithmic device"algorithmic device" means a device that uses one or more algorithms to perform calculations of data, including data concerning local or statewide rent amounts being charged to tenants by landlords, for the purpose of advising a landlord concerning the amount of rent that the landlord may consider charging a tenant. "Algorithmic device": (i) includes a product that incorporates an algorithmic device; and (ii) does not include: (A) any report published periodically, but no more frequently than monthly, by a trade association that receives renter data and publishes it in an aggregated and anonymous manner; or (B) a product used for the purpose of establishing rent or income limits in accordance with the affordable housing program guidelines of a local government, the state, the federal government, or other political subdivision.Real Prop. Law § 222-a(3)(a) has been the subject of lawsuits that allege such products pose a heightened risk of anticompetitive conduct, price fixing, and collusion, all of which allegedly result in higher rentsRent"Rent" means the total amount of rent, including concessions and fees, that a residential tenant is required to pay pursuant to a rental agreement.Real Prop. Law § 222-a(3)(c) for residential tenants, and allegedly poses the risk that landlords will outsource pricing decisions, which the legislature determines should always be made by the landlord. Therefore, the legislature declares that, with certain exceptions, the use of an algorithmic deviceAlgorithmic device"algorithmic device" means a device that uses one or more algorithms to perform calculations of data, including data concerning local or statewide rent amounts being charged to tenants by landlords, for the purpose of advising a landlord concerning the amount of rent that the landlord may consider charging a tenant.

Law § 222-a(3)(c) is prohibited.

Section 1 provides the legislative findings and purpose statement. The legislature finds that algorithmic rent-pricing devices have been the subject of lawsuits alleging heightened risk of anticompetitive conduct, price fixing, and collusion, resulting in higher rents for residential tenants. The legislature also expresses concern that landlords will outsource pricing decisions that should always be made by the landlord. This section creates no operative obligation.

Law § 222-a(3)(b).

Subdivision 1 is the bill's core operative prohibition. It bars landlords from employing, using, or relying upon — or causing another person to employ, use, or rely upon — an algorithmic device that uses, incorporates, or was trained with nonpublic competitor data when setting or changing residential rent. The prohibition covers initial rent-setting as well as renewal pricing. The scope is narrowed by the nonpublic-competitor-data qualifier: algorithmic tools that rely only on publicly available data are not prohibited. The carve-outs in the definition of algorithmic device further exclude aggregated trade-association reports and affordable-housing compliance tools.

Real Prop. Law § 222-a(2)
Enforcement — deceptive act or practice

(2) A violation of subdivision one of this section is a deceptive act or practice as provided in section three hundred forty-nine of the general business law, and a person who commits a violation is subject to all penalties and remedies described in article twenty-two-A of the general business law.

Subdivision 2 provides the enforcement mechanism by declaring any violation of subdivision 1 a deceptive act or practice under GBL § 349, incorporating all penalties and remedies available under Article 22-A of the General Business Law. This gives the Attorney General enforcement authority and provides a private right of action to injured tenants. This section creates no independent compliance obligation beyond the prohibition in subdivision 1.

Law § 222-a(3)(c), including concessions and fees, that a residential tenant is required to pay pursuant to a rental agreement.

Subdivision 3 defines the three key terms used in the operative prohibition: algorithmic device, nonpublic competitor data, and rent. The definition of algorithmic device is notable for its breadth — it covers any product incorporating an algorithm that calculates data for the purpose of advising a landlord on rent pricing — and for its two narrow carve-outs: aggregated trade-association reports published no more frequently than monthly, and affordable-housing compliance tools. The definition of nonpublic competitor data expressly includes anonymized data, preventing circumvention through data anonymization.

Effective date and applicability

Law § 222-a(3)(c) that the landlord charges for the occupancy of a residential premises pursuant to any rental agreement that is executed on or after the effective date of this act.
