About this building
City records list 1906 as the year built — older than 85% of the 354 buildings we cover in ZIP 10455, and the oldest of the 15 buildings we cover on this block. The building’s floor space is 3.3 times the size of its lot: 12,325 sq ft of building on a 3,750 sq ft lot.
Comparisons with neighboring buildings, as of October 21, 2026.
A difference between the DHCR rent-stabilized count and the PLUTO total is common and does not, on its own, indicate a violation: units can leave rent stabilization legally, the two datasets count units differently, some units may be non-residential, and a registration can be filed incompletely. To check your own apartment, see how to request your rent history from DHCR.

- City records show 121 open HPD violations, 35 immediately hazardous (Class C) at this building. Ask which are still unresolved in the unit and the landlord’s timeline to clear them.
- The oldest open violation on record dates to 2005 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 20 rent-stabilized units here. Ask whether this specific unit is one of them, and ask the landlord for its legal regulated rent and lease history.
- Confirm the condition behind the most recent open violation was actually repaired, not just marked closed: Replace or repair the self-closing doors that is missing or defective hinges at door….
- 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.
634 Prospect Avenue sits in Bronx, ZIP 10455. The closest subway is E 149 St (6) (4-minute walk), served by the 2, 5, and 6 lines.
Building Condition
Oldest open violation: April 2005 · Most recent: September 2026. 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.

1 open lead-paint hazard violation on record (most recent 2005). 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 1906). 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.
