Open violations are sitting, with little movement either way. 20 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 3623 15 Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 50 Class C violations, all 50 by the original certify-by date. HPD now marks 9 of them False Certification. 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 3623 15 Avenue, Brooklyn have active DOB violations?

Yes. 2 active DOB violations. The newest was issued November 20, 2013. 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 3623 15 Avenue, Brooklyn in housing court?

Yes. 1 open housing court case, opened March 30, 2021. 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.

Yes. 2 DOB complaints in the 12 months to September 25, 2026. The newest was filed August 13, 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.

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's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, DOB boiler inspection reports, 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's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, 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.
