Questions about this building

Is 2427 Dean Street, Brooklyn getting better or worse?

Certifications are being filed faster than new violations come in. 20 certifications filed against 1 new Class C 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 2427 Dean Street, Brooklyn?

Since October 12, 2023, certifications were filed on 2 Class C violations, all 2 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 2427 Dean Street, Brooklyn been in housing court?

Yes. 1 housing court case here, opened in 2008. HPD takes buildings to housing court to get violations fixed and heat and hot water restored, and it joins tenants' own repair cases, called tenant actions. A case stays open until the court closes it.

Does 2427 Dean Street, Brooklyn have a certificate of occupancy?

Its latest certificate of occupancy is a final one, issued May 25, 2022. A certificate of occupancy says how a building may be used and occupied. A temporary one lets people move in while work finishes and has to be renewed until DOB issues the final one. DOB's records here start in July 2012, so an older certificate may not show.

When did 2427 Dean Street, Brooklyn last file its bedbug report?

On April 29, 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 2427 Dean Street, Brooklyn built?

The city's record gives 1920 as the year 2427 Dean 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 2427 Dean Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 7 residential units at 2427 Dean 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, DOF's tax lien sale lists, HPD's housing court cases, DOB certificates of occupancy, HPD's annual bedbug reports, the city's PLUTO tax-lot file and DOF's property sales records. 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, DOF's tax lien sale lists, HPD's housing court cases, DOB certificates of occupancy, HPD's annual bedbug reports, the city's PLUTO tax-lot file and DOF's property sales records. 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.
