- City records show 127 open HPD violations, 30 immediately hazardous (Class C) under 678 St Nicholas Avenue — the address HPD files this building’s records under, not the address on this page. Ask which are still unresolved in the unit and the landlord’s timeline to clear them.
- The oldest open violation on record dates to 2009 — why has it stayed open this long, and is it in or near this unit?
- We found no DHCR rent-stabilization unit count for this building. That is not the same as the building being market-rate — a registration can be on file with no unit figure, or not have been filed at all. Ask the landlord directly whether the unit is rent-stabilized, and request your own rent history from DHCR.
- Confirm the condition behind the most recent open violation was actually repaired, not just marked closed: Repair the broken or defective plastered surfaces and paint in a uniform color at south….
- Confirm in person that the immediately-hazardous (Class C) conditions — typically heat, hot water, leaks, mold or pests — are genuinely fixed, not just marked closed.
678 Saint Nicholas Avenue sits in Manhattan, ZIP 10030. The closest subway is 145 St (A,C,B,D) (2-minute walk), served by the A, B, C, and D lines.
Building Condition
Oldest open violation: February 2009 · Most recent: July 2025. HPD marks a violation open until it is certified as corrected, so an old date can mean an unresolved condition or a repair that was never certified.

2 open lead-paint hazard violations on record (most recent 2009). These are HPD violations recorded against the building — not a test of any specific apartment.
6 earlier hazards cited and remediated.
Under NYC Local Law 1 (Admin Code §27-2056.5), lead paint is presumed present in common areas and in apartments where a child under 6 resides, in multiple dwellings built before 1960 (this building: built 1920). The presumption stands unless the owner obtained a lead-free or lead-safe exemption from HPD. Those exemption records aren’t published as open data, so we can’t confirm one either way.
