Questions about this building

Is 424 13 Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 1 open Class C, with nothing filed or new in the last 180 days. 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 424 13 Street, Brooklyn?

Since October 12, 2023, a certification was filed on 1 Class C violation, after 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.

Does 424 13 Street, Brooklyn have active DOB violations?

Yes. 21 active DOB violations, most of them for low-pressure boilers. The newest was issued June 30, 2023. 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.

When was the boiler at 424 13 Street, Brooklyn last inspected?

It has 7 boilers, all inspected in 2026, the latest on May 18. 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 424 13 Street, Brooklyn last file its bedbug report?

On May 18, 2026, 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 424 13 Street, Brooklyn built?

The city's record gives 1891 as the year 424 13 Street, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up building with 4 floors.

How many apartments does 424 13 Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 20 residential units at 424 13 Street, 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 OATH/ECB summonses from DOB and FDNY, DOB violations, DOB NOW work permits, 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 OATH/ECB summonses from DOB and FDNY, DOB violations, DOB NOW work permits, 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.
