Questions about this building
Does 1523 Undercliff Avenue, Bronx have open violations?
Yes. 1523 Undercliff Avenue, Bronx had 19 open violations on September 26, 2026: 1 from OATH/ECB and 18 from HPD. 12 are Class C, the class HPD treats as immediately hazardous.
Is 1523 Undercliff Avenue, Bronx getting better or worse?
Open violations are sitting, with little movement either way. 12 open Class C, with 1 certification filed and 1 new Class C in the last 180 days, too few to call a direction. That window ends September 26, 2026. It compares certifications filed with new Class C violations, and it describes what happened, not what anyone intends.
When were certifications filed on Class C violations at 1523 Undercliff Avenue, Bronx?
Since September 28, 2023, certifications were filed on 20 Class C violations: 19 by the original certify-by date, 1 after it. A certification is the filing, dated when it was made, not HPD's acceptance of it. It is compared with the original certify-by date on the notice. A granted postponement moves that date and the city's data keeps only the first, so a certification counted after it may still have met a postponed date.
Does 1523 Undercliff Avenue, Bronx have an OATH hearing coming up?
Yes. A hearing on a DOB summons is set for November 20, 2026. DOB summonses are heard at OATH, the city's hearings office, and OATH can move a hearing to a later date. When nobody shows up, the summons is decided by default, the costliest way one ends.
Does 1523 Undercliff Avenue, Bronx have active DOB violations?
Yes. 4 active DOB violations, most of them for low-pressure boilers. The newest was issued June 20, 2023. The Department of Buildings writes these separately from HPD's housing violations, for things like boilers, elevators, facades, construction and energy filings. Each one stays active until DOB resolves or dismisses it.
Has DOB received complaints about 1523 Undercliff Avenue, Bronx?
Yes. 2 DOB complaints in the last 12 months. The newest was filed August 28, 2026. Anyone can complain to DOB about a building or the work going on in it, and DOB then inspects and decides whether there is a violation. A conversion complaint says an apartment may have been added or changed without approval. It is a complaint, not a finding.
Are any HPD emergency repair orders at 1523 Undercliff Avenue, Bronx marked completed?
Yes. 1 completed HPD emergency repair order since September 28, 2023: a general construction order, opened April 4, 2025, awarded for $400. HPD orders an emergency repair when a hazardous condition cited in a violation, or in another agency's emergency order, is not corrected, and does the work itself or through a contractor. The amounts are what the orders were awarded for, not a bill: this page does not show what was charged to the property or whether it was paid. Orders for lab tests, such as dust-wipe and asbestos samples, are not counted.
What did the latest facade report find at 1523 Undercliff Avenue, Bronx?
Rated Safe in the latest facade report, filed April 6, 2022 (inspection cycle 9). Buildings taller than six stories must have their exterior walls inspected once in every inspection cycle under the city's Facade Inspection Safety Program (every five years under DOB's current rule), and each inspection report is filed with DOB as Safe, SWARMP (safe with a repair and maintenance program) or Unsafe. No Report Filed means DOB has no report for that cycle. The rating is from the latest filing and does not describe the facade today; DOB's page for the building shows anything filed since.
Does 1523 Undercliff Avenue, Bronx have a certificate of occupancy?
Its latest certificate of occupancy is a final one, issued February 1, 2013. A certificate of occupancy says how a building may be used and occupied. A temporary one lets people move in while work finishes and has to be renewed until DOB issues the final one. DOB's records here start in July 2012, so an older certificate may not show.
Is 1523 Undercliff Avenue, Bronx rent stabilized?
The building has rent-stabilized apartments on its 2024 registration. That comes from the Rent Guidelines Board's list of buildings with at least one stabilized apartment registered that year. Buildings that registered late are left off, and a 421-a or J-51 building can leave stabilization when its tax benefit ends. A particular apartment's status is for NYS HCR to say.
When was 1523 Undercliff Avenue, Bronx built?
The city's record gives 2011 as the year 1523 Undercliff Avenue, Bronx was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator apartment building with 8 floors.
How many apartments does 1523 Undercliff Avenue, Bronx have?
The Department of City Planning's PLUTO tax-lot file lists 15 residential units at 1523 Undercliff Avenue, Bronx. The count is for the whole tax lot.
Where do these numbers come from?
From New York City's own data: HPD housing violations and OATH/ECB hearing results, read whole rather than sampled. It also draws on OATH hearing dates, DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, DOB certificates of occupancy, HPD emergency repair orders and the city's PLUTO tax-lot file. This page is current through September 26, 2026. The city's data changes daily, so a violation certified after that can still show as open here; the city's own page for this building is linked above.
