About this building
The building’s floor space is 4.7 times the size of its lot: 21,730 sq ft of building on a 4,658 sq ft lot.
Comparisons with neighboring buildings, as of October 31, 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 42 open HPD violations, 18 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 2018 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 25 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 latch at door leading….
- 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.
2105 Blackrock Avenue sits in Bronx, ZIP 10472. The closest subway is Castle Hill Av (6) (8-minute walk), served by the 6 line.
Building Condition
Oldest open violation: December 2018 · Most recent: October 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.

18 lead-paint hazards cited and later remediated (most recent 2023); no open hazards on record. Remediation addresses the cited conditions, not necessarily every painted surface.
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 1927). 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.
Also on record: 6 procedural §27-2056 violations (failure to file required lead paperwork, most recent 2023) — a records failure, not evidence of a lead hazard.
