Questions about this building

Does 351 West 51 Street, Manhattan have open violations?

Yes. 351 West 51 Street, Manhattan had 13 open violations on September 27, 2026: 1 from OATH/ECB and 12 from HPD. 10 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 39 years, since May 11, 1987.

Is 351 West 51 Street, Manhattan getting better or worse?

Open violations are sitting, with little movement either way. 10 open Class C, with 1 certification filed and 0 new Class C in the last 180 days, too few to call a direction. That window ends September 27, 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 351 West 51 Street, Manhattan?

Since September 29, 2023, certifications were filed on 18 Class C violations: 11 by the original certify-by date, 7 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.

Does 351 West 51 Street, Manhattan have an OATH hearing coming up?

Yes. A hearing on a DOB summons is set for March 5, 2027. 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 351 West 51 Street, Manhattan have active DOB violations?

Yes. 2 active DOB violations, most of them for construction. The newest was issued October 29, 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.

When was the boiler at 351 West 51 Street, Manhattan last inspected?

On August 18, 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 351 West 51 Street, Manhattan last file its bedbug report?

On December 1, 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 351 West 51 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 351 West 51 Street, Manhattan built?

The city's record gives 1920 as the year 351 West 51 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 3 floors.

How many apartments does 351 West 51 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 10 residential units at 351 West 51 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, the Rent Guidelines Board's stabilized-building lists, DOB boiler inspection reports, HPD's annual bedbug reports and the city's PLUTO tax-lot file. This page is current through September 27, 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, the Rent Guidelines Board's stabilized-building lists, 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.
