Top insights
- More open HPD violations than ~65% of buildings in this ZIP (45 open)
- 16 open hazardous (Class C) violations
- Built in 2011 (city records)
- Rent-stabilized: 30 units registered
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 45 open HPD violations, 16 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 2017 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 30 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: Abate the infestation consisting of mice in the entire apartment.
- 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.
1523 Undercliff Avenue sits in Bronx, ZIP 10453. No subway stations are within an 800-meter walk — expect to rely on buses or rideshare.
Building Condition
Oldest open violation: September 2017. 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.
