About this building
City records list 1950 as the year built — newer than 87% of the 881 buildings we cover in ZIP 11233. 8 apartments — the most of any of the 16 buildings we cover on this block. The building’s floor space is 2.1 times the size of its lot: 6,732 sq ft of building on a 3,200 sq ft lot.
Comparisons with neighboring buildings, as of October 28, 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 14 open HPD violations, 2 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 2021 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 3 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: Post notice, in form approved by the department, stating the name and location….
- 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.
237 Ralph Avenue sits in Brooklyn, ZIP 11233. The closest subway is Ralph Av (C) (4-minute walk), served by the A, C, and J lines.
Building Condition
Oldest open violation: March 2021 · Most recent: May 2021. 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.

No HPD lead-paint violations are on record for this building. That means no complaint or inspection was filed — not that the building is lead-free.
Built 1950. 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. 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.
