Questions about this building

Is 524 West 123 Street, Manhattan getting better or worse?

Certifications are being filed about as fast as new violations come in. 7 certifications filed and 11 new Class C in the last 180 days, neither far ahead. That window ends September 26, 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 524 West 123 Street, Manhattan?

Since September 28, 2023, certifications were filed on 15 Class C violations, all 15 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.

Has DOB received complaints about 524 West 123 Street, Manhattan?

Yes. 5 DOB complaints in the last 12 months. The newest was filed May 15, 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.

Is 524 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 524 West 123 Street, Manhattan built?

The city's record gives 1926 as the year 524 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 524 West 123 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 10 residential units at 524 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 DOB complaints, the Rent Guidelines Board's stabilized-building lists and the city's PLUTO tax-lot file. This page is current through September 26, 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 complaints, the Rent Guidelines Board's stabilized-building lists 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.
