Questions about this building

Does 2121 1 Avenue, Manhattan have open violations?

Yes. 2121 1 Avenue, Manhattan had 1 open violation on October 10, 2026: 1 from HPD. None of them is Class C, but counting every year, HPD has 24 Class C violations still open here. The oldest open HPD violation has been open 40 years, since September 2, 1986.

When were certifications filed on Class C violations at 2121 1 Avenue, Manhattan?

Since October 12, 2023, a certification was filed on 1 Class C violation, 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 2121 1 Avenue, Manhattan have active DOB violations?

Yes. 1 active DOB violation, issued June 30, 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 2121 1 Avenue, Manhattan been in housing court?

Yes. 3 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.

When was the boiler at 2121 1 Avenue, Manhattan last inspected?

On December 15, 2025. 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 2121 1 Avenue, Manhattan last file its bedbug report?

On December 18, 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.

When was 2121 1 Avenue, Manhattan built?

The city's record gives 1910 as the year 2121 1 Avenue, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a residence with stores or offices with 4 floors.

How many apartments does 2121 1 Avenue, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 6 residential units at 2121 1 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 NOW work permits, DOB boiler inspection reports, HPD's annual bedbug reports 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, DOB violations, HPD's housing court cases, DOB NOW work permits, DOB boiler inspection reports, HPD's annual bedbug reports 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.
