Rent stabilization

Rent-stabilized units: 2018: 122 → 2024: 113
Down 9 units (7%) since 2018 — a signal of deregulation and tenant turnover pressure.
Are you paying a legal rent?
If your apartment is one of these stabilized units, you have rights most renters don't: yearly increases capped by the NYC Rent Guidelines Board, a guaranteed lease renewal, and eviction protections. Overcharges are common — and refundable if you catch them.
Check it free: request your apartment's official rent history from NY State (HCR). It lists every registered rent since 1984 and shows whether you're being overcharged.
Free from NY State's rent agency (HCR) — request your own apartment; the history is mailed to you in ~2–6 weeks. Information, not legal advice; whether your specific unit is stabilized depends on its own history. Rent stabilization & the 2026 rent freeze, explained →
