Is 664 Union Avenue, Bronx getting better or worse?

Certifications are being filed about as fast as new violations come in. 6 certifications filed and 5 new Class C in the last 180 days, neither far ahead. 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 664 Union Avenue, Bronx?

Since September 29, 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.

Has DOB received complaints about 664 Union Avenue, Bronx?

Yes. 3 DOB complaints in the 12 months to September 25, 2026. The newest was filed July 24, 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. A conversion complaint says an apartment may have been added or changed without approval. It is a complaint, not a finding.

Does 664 Union Avenue, Bronx have a certificate of occupancy?

Its latest certificate of occupancy is a final one, issued April 14, 2025. 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 664 Union Avenue, Bronx last file its bedbug report?

On March 11, 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 664 Union Avenue, Bronx built?

The city's record gives 1901 as the year 664 Union Avenue, Bronx was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up apartment building with 3 floors.

How many apartments does 664 Union Avenue, Bronx have?

The Department of City Planning's PLUTO tax-lot file lists 10 residential units at 664 Union Avenue, Bronx. 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 hearing dates, HPD's housing court cases, DOB complaints, DOB certificates of occupancy, 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 OATH hearing dates, HPD's housing court cases, DOB complaints, DOB certificates of occupancy, 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.
