Questions about this building

Does 526 West 123 Street, Manhattan have open violations?

Yes. 526 West 123 Street, Manhattan had 21 open violations on September 27, 2026: 21 from HPD. 16 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 2 years, since September 10, 2024.

Is 526 West 123 Street, Manhattan getting better or worse?

New violations are coming in faster than certifications are filed. 10 new Class C against 5 certifications filed 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 526 West 123 Street, Manhattan?

Since September 29, 2023, certifications were filed on 9 Class C violations, all 9 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.

When was the boiler at 526 West 123 Street, Manhattan last inspected?

On October 25, 2025. 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 526 West 123 Street, Manhattan last file its bedbug report?

On December 26, 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 526 West 123 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 526 West 123 Street, Manhattan built?

The city's record gives 1926 as the year 526 West 123 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 526 West 123 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 10 residential units at 526 West 123 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 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 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.
