About this building
The building’s floor space is 2.8 times the size of its lot: 6,200 sq ft of building on a 2,186 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 6 open HPD violations, 1 immediately hazardous (Class C) under 454 Union 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 2011 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 5 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: Install the missing or repair/replace the defective window guard(s) in accordance….
- 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.
448 Union Avenue sits in Brooklyn, ZIP 11211. The closest subway is Metropolitan Av/Lorimer St (G,L) (1-minute walk), served by the G, J, L, and M lines.
Building Condition
Oldest open violation: November 2011 · Most recent: May 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.

5 lead-paint hazards cited and later remediated (most recent 2025); 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 1930). 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.
