Rent stabilization is NYC's primary rent regulation system, affecting approximately 1 million apartments. Key features include limited annual rent increases (set by the Rent Guidelines Board), lease renewal rights for tenants, and succession rights. Buildings can become stabilized through tax benefit programs like 421-a and J-51, even if they wouldn't otherwise qualify.
