Questions about this building

Does 721 Willoughby Avenue, Brooklyn have open violations?

Yes. 721 Willoughby Avenue, Brooklyn had 46 open violations on September 26, 2026: 45 from HPD and 1 from OATH/ECB. 12 are Class C, the class HPD treats as immediately hazardous.

Is 721 Willoughby Avenue, Brooklyn getting better or worse?

Certifications are being filed faster than new violations come in. 7 certifications filed against 3 new Class C in the last 180 days. That window ends September 26, 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 721 Willoughby Avenue, Brooklyn?

Since September 28, 2023, certifications were filed on 19 Class C violations, all 19 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.

Does 721 Willoughby Avenue, Brooklyn have an OATH hearing coming up?

Yes. A hearing on a DOB summons is set for October 28, 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.

Does 721 Willoughby Avenue, Brooklyn have active DOB violations?

Yes. 4 active DOB violations, most of them for boiler filings under Local Law 62/91. The newest was issued December 1, 2024. 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 721 Willoughby Avenue, Brooklyn in housing court?

Yes. 1 open housing court case, opened May 12, 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 721 Willoughby Avenue, Brooklyn?

Yes. 2 DOB complaints in the last 12 months. The newest was filed July 15, 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.

What did the latest facade report find at 721 Willoughby Avenue, Brooklyn?

Rated Safe in the latest facade report, filed July 16, 2023 (inspection cycle 9). Buildings taller than six stories must have their exterior walls inspected once in every inspection cycle under the city's Facade Inspection Safety Program (every five years under DOB's current rule), and each inspection report is filed with DOB as Safe, SWARMP (safe with a repair and maintenance program) or Unsafe. No Report Filed means DOB has no report for that cycle. The rating is from the latest filing and does not describe the facade today; DOB's page for the building shows anything filed since.

Are any DOB work permits in effect at 721 Willoughby Avenue, Brooklyn?

Yes. 1 DOB work permit in effect, for Mechanical Systems work, issued July 31, 2026. A permit in effect allows the work it names. It does not mean the work has started or finished, or that it fixes any violation on this page.

Is 721 Willoughby Avenue, Brooklyn covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered under Article 321, the path for certain affordable housing and houses of worship (DOB's list, March 1, 2026). Local Law 97 sets greenhouse gas limits for most New York City buildings over 25,000 square feet, and DOB's covered buildings list says which path each building is on. The list reflects DOB's records, which owners can ask DOB to correct. This page never estimates a penalty or says whether a building complies.

When was 721 Willoughby Avenue, Brooklyn built?

The city's record gives 1976 as the year 721 Willoughby Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator apartment building with 4 floors.

How many apartments does 721 Willoughby Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 267 residential units at 721 Willoughby 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 OATH hearing dates, DOB violations, HPD's housing court cases, DOB complaints, DOB facade filings, DOB NOW work permits, DOB's Local Law 97 covered buildings list and the city's PLUTO tax-lot file. This page is current through September 26, 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, DOB violations, HPD's housing court cases, DOB complaints, DOB facade filings, DOB NOW work permits, DOB's Local Law 97 covered buildings list 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.
