Is 511 West 147 Street, Manhattan getting better or worse?

Certifications are being filed faster than new violations come in. 55 certifications filed against 10 new Class C in the last 180 days. 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 511 West 147 Street, Manhattan?

Since September 29, 2023, certifications were filed on 34 Class C violations, all 34 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.

Is 511 West 147 Street, Manhattan in housing court?

Yes. 2 open housing court cases. The newest opened May 19, 2026. 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.

Has DOB received complaints about 511 West 147 Street, Manhattan?

Yes. 3 DOB complaints in the 12 months to September 25, 2026. The newest was filed August 29, 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 511 West 147 Street, Manhattan?

Yes. 1 DOB work permit in effect, for Plumbing work, issued October 15, 2025. 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 511 West 147 Street, Manhattan last file its bedbug report?

On December 16, 2024, for the year to October 31, 2024. 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 511 West 147 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 511 West 147 Street, Manhattan built?

The city's record gives 1930 as the year 511 West 147 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 511 West 147 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 21 residential units at 511 West 147 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 HPD's housing court cases, 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 HPD's housing court cases, 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.
