Questions about this building

Does 634 Osborn Street, Brooklyn have open violations?

Yes. 634 Osborn Street, Brooklyn had 60 open violations on September 27, 2026: 60 from HPD. 13 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 32 years, since August 12, 1994.

Is 634 Osborn Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 13 open Class C, with 0 certifications filed and 1 new Class C in the last 180 days, too few to call a direction. 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 634 Osborn Street, Brooklyn?

Since September 29, 2023, certifications were filed on 6 Class C violations, all 6 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 634 Osborn Street, Brooklyn in housing court?

Yes. 1 open housing court case. 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.

Are any HPD emergency repair orders at 634 Osborn Street, Brooklyn marked completed?

Yes. 4 completed HPD emergency repair orders since September 29, 2023, awarded for $4,263 in total. The most recent of the 4, a general construction order, was opened January 19, 2026. 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 634 Osborn Street, 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.

When was 634 Osborn Street, Brooklyn built?

How many apartments does 634 Osborn Street, Brooklyn have?

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 housing court cases, 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 housing court cases, 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.
