Establishes certain criteria for the rent guidelines board to use for purposes of determining annual rent adjustments

S 2219 requires New York City's Rent Guidelines Board to use specific criteria when calculating annual rent adjustments for rent-stabilized properties. The bill mandates the Board to consider all property sizes, categorize owners by unit count (including rent-stabilized units), gross rent, and income, and publicly disclose data sources like the Department of Finance's real property forms. It also restricts hardship rent increases to owners with 20 or fewer units citywide and prohibits these increases for limited liability companies and large real estate firms. This directly affects rent-stabilized housing landlords and tenants in New York City by changing how rent adjustments are calculated and who qualifies for certain increases.
