Questions about this building

Does 521 West 144 Street, Manhattan have open violations?

Yes. 521 West 144 Street, Manhattan had 17 open violations on October 10, 2026: 17 from HPD. 5 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 4 years, since August 30, 2022.

Is 521 West 144 Street, Manhattan getting better or worse?

Open violations are sitting, with little movement either way. 5 open Class C, with 0 certifications filed and 1 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 521 West 144 Street, Manhattan?

Since October 12, 2023, certifications were filed on 6 Class C violations: 5 by the original certify-by date, 1 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.

Has 521 West 144 Street, Manhattan been in housing court?

Yes. 6 housing court cases here since 2006, most of them tenant actions. 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.

Are any HPD emergency repair orders at 521 West 144 Street, Manhattan marked completed?

Yes. 1 completed HPD emergency repair order since October 12, 2023: a general construction order, opened March 12, 2025, awarded for $753. 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.

Does 521 West 144 Street, Manhattan have a certificate of occupancy?

Its latest certificate of occupancy is a final one, issued February 1, 2013. A certificate of occupancy says how a building may be used and occupied. A temporary one lets people move in while work finishes and has to be renewed until DOB issues the final one. DOB's records here start in July 2012, so an older certificate may not show.

When was the boiler at 521 West 144 Street, Manhattan last inspected?

On February 26, 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 521 West 144 Street, Manhattan last file its bedbug report?

On January 1, 2025, 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 521 West 144 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.

Does 521 West 144 Street, Manhattan have a property tax exemption?

The building has a 420-c tax exemption on DOF's 2026/27 roll. An exemption lowers a property's tax bill by reducing its assessed value.

When was 521 West 144 Street, Manhattan built?

The city's record gives 1880 as the year 521 West 144 Street, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up building with 5 floors.

How many apartments does 521 West 144 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 15 residential units at 521 West 144 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, the Rent Guidelines Board's stabilized-building lists, DOF's exemption rolls, DOB certificates of occupancy, 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 HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, DOF's exemption rolls, DOB certificates of occupancy, 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.
