Is 624 Riverdale Avenue, Brooklyn getting better or worse?

New violations are coming in faster than certifications are filed. 16 new Class C against 8 certifications filed 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 624 Riverdale Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 18 Class C violations, all 18 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.

Is 624 Riverdale Avenue, Brooklyn in HPD's Alternative Enforcement Program?

Yes. In HPD's Alternative Enforcement Program since January 31, 2018. HPD puts a group of buildings with serious, long-running violations into the program each year. While a building is in it, HPD can make repairs itself and charge the cost to the property, and the building stays in until HPD discharges it.

Does 624 Riverdale Avenue, Brooklyn have active DOB violations?

Yes. 37 active DOB violations, most of them for boiler filings under Local Law 62/91. The newest was 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 624 Riverdale Avenue, Brooklyn in housing court?

Yes. 3 open housing court cases. The newest opened May 14, 2026. 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.

Has DOB received complaints about 624 Riverdale Avenue, Brooklyn?

Yes. 1 DOB complaint in the 12 months to September 25, 2026. It was filed November 13, 2025. 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. A conversion complaint says an apartment may have been added or changed without approval. It is a complaint, not a finding.

Are any HPD emergency repair orders at 624 Riverdale Avenue, Brooklyn marked completed?

Yes. 2 completed HPD emergency repair orders since September 29, 2023, awarded for $969 in total. The most recent of the 2, a general construction order, was opened December 26, 2025. 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 624 Riverdale Avenue, Brooklyn last file its bedbug report?

On May 12, 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.

How many apartments does 624 Riverdale Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 6 residential units at 624 Riverdale 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 HPD's Alternative Enforcement Program list, DOB violations, HPD's housing court cases, DOB complaints, 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 HPD's Alternative Enforcement Program list, DOB violations, HPD's housing court cases, DOB complaints, 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.
