Questions about this building

Does 509 West 142 Street, Manhattan have open violations?

Yes. 509 West 142 Street, Manhattan had 39 open violations on October 10, 2026: 37 from HPD and 2 from OATH/ECB. 8 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 9 years, since October 18, 2016.

Is 509 West 142 Street, Manhattan getting better or worse?

Open violations are sitting, with little movement either way. 8 open Class C, with 2 certifications filed and 4 new Class C in the last 180 days, too few to call a direction. That window ends October 10, 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 509 West 142 Street, Manhattan?

Since October 12, 2023, certifications were filed on 5 Class C violations, all 5 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 509 West 142 Street, Manhattan have active DOB violations?

Yes. 3 active DOB violations. The newest was issued April 27, 2022. 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 509 West 142 Street, Manhattan been in housing court?

Yes. 2 housing court cases here since 2014. 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 509 West 142 Street, Manhattan?

Yes. 1 DOB complaint in the 12 months to September 25, 2026. It was filed May 1, 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 509 West 142 Street, Manhattan marked completed?

Yes. 3 completed HPD emergency repair orders since October 12, 2023, awarded for $3,374 in total. The most recent of the 3, a general construction order, was opened August 7, 2026. 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.

When was the boiler at 509 West 142 Street, Manhattan last inspected?

On July 7, 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 509 West 142 Street, Manhattan last file its bedbug report?

On April 24, 2026, 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 509 West 142 Street, Manhattan built?

The city's record gives 1910 as the year 509 West 142 Street, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator building with 6 floors.

How many apartments does 509 West 142 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 12 residential units at 509 West 142 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/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, DOB complaints, HPD emergency repair orders, 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 complaints, HPD emergency repair orders, 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.
