Questions about this building

Does 45 St Nicholas Avenue, Manhattan have open violations?

Yes. 45 St Nicholas Avenue, Manhattan had 43 open violations on September 26, 2026: 43 from HPD. 16 are Class C, the class HPD treats as immediately hazardous.

Is 45 St Nicholas Avenue, Manhattan getting better or worse?

New violations are coming in faster than certifications are filed. 11 new Class C against 5 certifications filed in the last 180 days. 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 45 St Nicholas Avenue, Manhattan?

Since September 28, 2023, certifications were filed on 77 Class C violations: 75 by the original certify-by date, 2 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.

Does 45 St Nicholas Avenue, Manhattan have active DOB violations?

Yes. 1 active DOB violation, issued November 14, 2025. 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.

Is 45 St Nicholas Avenue, 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 45 St Nicholas Avenue, Manhattan built?

The city's record gives 1900 as the year 45 St Nicholas Avenue, 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 45 St Nicholas Avenue, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 12 residential units at 45 St Nicholas Avenue, 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 violations, 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 violations, 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.
