## Summary

Creates the Prohibition of Algorithmics in Rent Act. Provides that in setting the amount of rent to be charged to a tenant for the occupancy of a residential premises, including determining any change in the amount of rent to be charged for the renewed occupancy of a residential premises, a landlord shall not employ, use, or rely upon, or cause another person to employ, use, or rely upon, an algorithmic device that uses, incorporates, or was trained with nonpublic competitor data. Defines "algorithmic device" to mean 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. Provides that this definition does not include (i) 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 (ii) 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. Amends the Consumer Fraud and Deceptive Business Practices Act to make a corresponding change. Provides that any person who violates the Prohibition of Algorithmics in Rent Act commits an unlawful practice within the meaning of the Consumer Fraud and Deceptive Business Practices Act.
