Your details stay with us, and go only to the one firm you are introduced to. No lists, no resale.

Questions about this building

Does 21 West 137 Street, Manhattan have open violations?

Yes. 21 West 137 Street, Manhattan had 50 open violations on September 26, 2026: 44 from HPD and 6 from OATH/ECB. 14 are Class C, the class HPD treats as immediately hazardous.

Is 21 West 137 Street, Manhattan getting better or worse?

Open violations are sitting, with little movement either way. 14 open Class C, with 1 certification filed and 8 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 21 West 137 Street, Manhattan?

Since September 28, 2023, certifications were filed on 2 Class C violations, all 2 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 21 West 137 Street, Manhattan have an OATH hearing coming up?

Yes. 3 hearings scheduled on DOB summonses, the first on October 1, 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 21 West 137 Street, Manhattan have active DOB violations?

Yes. 2 active DOB violations. The newest was issued August 1, 2025. 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 21 West 137 Street, Manhattan?

Yes. 2 DOB complaints in the last 12 months. The newest was filed July 27, 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 21 West 137 Street, Manhattan marked completed?

Yes. 1 completed HPD emergency repair order since September 28, 2023: a general construction order, opened June 10, 2025, awarded for $1,782. 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.

Is 21 West 137 Street, 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 137 Street, Manhattan built?

The city's record gives 1920 as the year 21 West 137 Street, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up apartment building with 6 floors.

How many apartments does 21 West 137 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 18 residential units at 21 West 137 Street, 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 hearing dates, DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, 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.

Sources. HPD housing violations and OATH/ECB hearing results, plus OATH hearing dates, DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders 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.
