Questions about this building

Does 101 West End Avenue, Manhattan have open violations?

No. On October 10, 2026, 101 West End Avenue, Manhattan had no open HPD violations, counting every year, and no OATH/ECB summons issued in the last 3 years was still active.

When were certifications filed on Class C violations at 101 West End Avenue, Manhattan?

Since October 12, 2023, certifications were filed on 3 Class C violations, all 3 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 101 West End Avenue, Manhattan have active DOB violations?

Yes. 2 active DOB violations. The newest was issued November 19, 2004. 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 101 West End Avenue, Manhattan been in housing court?

Yes. 2 housing court cases here since 2020, most of them tenant actions. 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.

Has DOB received complaints about 101 West End Avenue, Manhattan?

Yes. 3 DOB complaints in the 12 months to September 25, 2026. The newest was filed September 18, 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.

What did the latest facade report find at 101 West End Avenue, Manhattan?

Rated Safe in the latest facade report, filed February 20, 2024 (inspection cycle 9). Reports in earlier inspection cycles rated it Safe in 2008 and 2013, and SWARMP in 2019. 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 101 West End Avenue, Manhattan have a certificate of occupancy?

Its latest certificate of occupancy is temporary, renewed August 20, 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.

What is the ENERGY STAR score for 101 West End Avenue, Manhattan?

ENERGY STAR score 54 for 2024, against a median of 67 for Multifamily Housing that year. Buildings over 25,000 square feet report their energy use to the city every year under Local Law 84. The ENERGY STAR score runs from 1 to 100 and compares a building with similar ones nationwide; 50 is the national median. The score is the one the city publishes, and this page never estimates a Local Law 97 emissions penalty. A lot that reported several properties in one year is not scored here.

When was the boiler at 101 West End Avenue, Manhattan last inspected?

It has 3 boilers, inspected between December 19, 2025 and June 16, 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 101 West End Avenue, Manhattan last file its bedbug report?

On December 4, 2025, 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 101 West End Avenue, Manhattan covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered from 2035 as an income-restricted building (DOB's list, March 1, 2026). Local Law 97 sets greenhouse gas limits for most New York City buildings over 25,000 square feet, and DOB's covered buildings list says which path each building is on. The list reflects DOB's records, which owners can ask DOB to correct. This page never estimates a penalty or says whether a building complies.

Is 101 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 101 West End Avenue, Manhattan built?

The city's record gives 1999 as the year 101 West End Avenue, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator building with 33 floors.

How many apartments does 101 West End Avenue, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 503 residential units at 101 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, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, DOB NOW work permits, DOB certificates of occupancy, Local Law 84 energy reports, DOB boiler inspection reports, HPD's annual bedbug reports, DOB's Local Law 97 covered buildings list, 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, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, DOB NOW work permits, DOB certificates of occupancy, Local Law 84 energy reports, DOB boiler inspection reports, HPD's annual bedbug reports, DOB's Local Law 97 covered buildings list, 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.
