Questions about this building

Does 21 West End Avenue, Manhattan have open violations?

Yes. 21 West End Avenue, Manhattan had 4 open violations on October 10, 2026: 1 from HPD and 3 from OATH/ECB. None is Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 5 years, since December 18, 2020.

When were certifications filed on Class C violations at 21 West End Avenue, Manhattan?

Since October 12, 2023, certifications were filed on 2 Class C violations: 1 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.

Has 21 West End Avenue, Manhattan been in housing court?

Yes. 1 housing court case here, opened in 2024. 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.

Does 21 West End Avenue, Manhattan have a certificate of occupancy?

Its latest certificate of occupancy is temporary, issued February 25, 2021. 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 21 West End Avenue, Manhattan?

ENERGY STAR score 47 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 did 21 West End Avenue, Manhattan last file its bedbug report?

On December 10, 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 21 West End Avenue, Manhattan covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered under Article 321, the path for certain affordable housing and houses of worship (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 21 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 21 West End Avenue, Manhattan built?

The city's record gives 2013 as the year 21 West End Avenue, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a condominium with 43 floors.

How many apartments does 21 West End Avenue, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 616 residential units at 21 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, HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, DOB NOW work permits, DOB certificates of occupancy, Local Law 84 energy reports, HPD's annual bedbug reports, DOB's Local Law 97 covered buildings list and the city's PLUTO tax-lot file. 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, HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, DOB NOW work permits, DOB certificates of occupancy, Local Law 84 energy reports, HPD's annual bedbug reports, DOB's Local Law 97 covered buildings list and the city's PLUTO tax-lot file. 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.
