Why

• Built 2005, 10 residential units, class D1.
• 421-a abatement (2010-2025) expired 1yr ago, but DHCR registry still shows 10 stabilized units as of 2024 — HSTPA 2019 generally keeps post-abatement units stabilized.

Tools

1. Get help with your DHCR rent history (NYC PEU) ↗ The NYC Mayor's Public Engagement Unit walks tenants through requesting their DHCR rent history at no cost. The rent history is the only document that definitively shows whether your specific unit is rent-stabilized and what the legal regulated rent is.
2. Check your lease for the 421-a or J-51 rider ↗ If your building has an abatement, your lease should include a rider disclosing it and stating that your unit is rent-stabilized while the abatement runs. Missing rider is itself a red flag.
3. File a rent overcharge complaint (Form DRA-910) ↗ If your rent looks higher than the stabilized maximum on your rent history, you can file DRA-910 with HCR. Treble damages and attorney fees are recoverable.
4. Find a tenant attorney ↗ Housing Court Answers maintains a directory of free and low-cost tenant lawyers across NYC. Overcharge cases often qualify for free legal representation.
