When were certifications filed on Class C violations at 664 Union Avenue, Bronx?
Since September 28, 2023, certifications were filed on 5 Class C violations: 4 by the original certify-by date, 1 after it. 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 664 Union Avenue, Bronx have an OATH hearing coming up?
Yes. A hearing on a DOB summons is set for October 16, 2026. DOB summonses are heard at OATH, the city's hearings office, and OATH can move a hearing to a later date. When nobody shows up, the summons is decided by default, the costliest way one ends.
Is 664 Union Avenue, Bronx in housing court?
Yes. 1 open housing court case, opened June 8, 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.

Yes. 3 DOB complaints in the last 12 months. The newest was filed July 24, 2026.
