Questions about this building

Does 1631 St Marks Avenue, Brooklyn have open violations?

Yes. 1631 St Marks Avenue, Brooklyn had 20 open violations on September 27, 2026: 20 from HPD. 11 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 7 years, since August 6, 2019.

Is 1631 St Marks Avenue, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 11 open Class C, with nothing filed or new 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 1631 St Marks Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 64 Class C violations: 62 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 1631 St Marks Avenue, Brooklyn have active DOB violations?

Yes. 1 active DOB violation, issued August 16, 1993. 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.

Are any HPD emergency repair orders at 1631 St Marks Avenue, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since September 29, 2023: a general construction order, opened September 29, 2025, awarded for $490. 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 did 1631 St Marks Avenue, Brooklyn last file its bedbug report?

On December 18, 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.

When was 1631 St Marks Avenue, Brooklyn built?

The city's record gives 1910 as the year 1631 St Marks Avenue, Brooklyn 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 4 floors.

How many apartments does 1631 St Marks Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 8 residential units at 1631 St Marks Avenue, Brooklyn. 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, HPD emergency repair orders, 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 DOB violations, HPD emergency repair orders, 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.
