Questions about this building

Does 851 West End Avenue, Manhattan have open violations?

Yes. 851 West End Avenue, Manhattan had 1 open violation on October 10, 2026: 1 from HPD. 1 is Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 8 years, since November 30, 2017.

Is 851 West End Avenue, Manhattan getting better or worse?

Open violations are sitting, with little movement either way. 1 open Class C, with nothing filed or new in the last 180 days. That window ends October 10, 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 851 West End Avenue, Manhattan?

Since October 12, 2023, certifications were filed on 24 Class C violations, all 24 by the original certify-by date. 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 851 West End Avenue, Manhattan have active DOB violations?

Yes. 2 active DOB violations. The newest was issued December 13, 2017. 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 851 West End Avenue, Manhattan been in housing court?

Yes. 5 housing court cases here since 2015. HPD takes buildings to housing court to get violations fixed and heat and hot water restored, and it joins tenants' own repair cases, called tenant actions. A case stays open until the court closes it.

Are any HPD emergency repair orders at 851 West End Avenue, Manhattan marked completed?

Yes. 2 completed HPD emergency repair orders since October 12, 2023, awarded for $799 in total. The most recent of the 2, a general construction order, was opened January 15, 2024. 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 851 West End Avenue, Manhattan?

Rated Safe in the latest facade report, filed May 3, 2023 (inspection cycle 9). An earlier report in this cycle, filed December 16, 2022, rated it Unsafe. Reports in earlier inspection cycles rated it Unsafe in 2017 and SWARMP in 2020. SWARMP means safe with a repair and maintenance program. 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 851 West End Avenue, Manhattan have a certificate of occupancy?

Its latest certificate of occupancy is a final one, issued August 14, 2026. 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.

When was the boiler at 851 West End Avenue, Manhattan last inspected?

On August 1, 2026. DOB requires a boiler in a building with 6 or more apartments to be inspected once every calendar year, with the report filed within 14 days of the inspection. Low-pressure boilers in residential buildings with 5 or fewer apartments are exempt.

When did 851 West End Avenue, Manhattan last file its bedbug report?

On March 23, 2026, for the year to October 31, 2025. HPD asks the owner of every building with 3 or more apartments for this report once a year, covering November 1 to October 31, including buildings that had no bedbugs.

Is 851 West End Avenue, Manhattan 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 851 West End Avenue, Manhattan built?

The city's record gives 1905 as the year 851 West End Avenue, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up building with 6 floors.

How many apartments does 851 West End Avenue, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 18 residential units at 851 West End Avenue, Manhattan. 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/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, DOB NOW work permits, DOB certificates of occupancy, HPD emergency repair orders, DOB boiler inspection reports, HPD's annual bedbug reports, the city's PLUTO tax-lot file and DOF's property sales records. This page is current through October 10, 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.

Sources. HPD housing violations and OATH/ECB hearing results, plus OATH/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, DOB NOW work permits, DOB certificates of occupancy, HPD emergency repair orders, DOB boiler inspection reports, HPD's annual bedbug reports, the city's PLUTO tax-lot file and DOF's property sales records. Counts cover HPD Class B and C violations from the last 3 years that HPD still shows open, and OATH/ECB summonses from the same 3 years that the city still shows active. The city's own pages can show more, never fewer.
