Is 351 West 45 Street, Manhattan getting better or worse?

Open violations are sitting, with little movement either way. 10 open Class C, with 2 certifications filed and 3 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 45 Street, Manhattan?

Since September 29, 2023, certifications were filed on 11 Class C violations, all 11 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 351 West 45 Street, Manhattan have active DOB violations?

Yes. 7 active DOB violations, most of them for low-pressure boilers. The newest was issued November 14, 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 351 West 45 Street, Manhattan?

Yes. 16 DOB complaints in the 12 months to September 25, 2026. The newest was filed May 2, 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 DOB work permits in effect at 351 West 45 Street, Manhattan?

Yes. 5 DOB work permits in effect. The latest, for General Construction work, was issued April 24, 2026. A permit in effect allows the work it names. It does not mean the work has started or finished, or that it fixes any violation on this page.

When did 351 West 45 Street, Manhattan last file its bedbug report?

Its 4 buildings had all filed by 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 45 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 45 Street, Manhattan built?

The city's record gives 1920 as the year 351 West 45 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 5 floors.

How many apartments does 351 West 45 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 80 residential units at 351 West 45 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 DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB NOW work permits, 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 DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB NOW work permits, 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.
