Questions about this building

Does 3401 Avenue J, Brooklyn have open violations?

Yes. 3401 Avenue J, Brooklyn had 31 open violations on September 26, 2026: 31 from HPD. 17 are Class C, the class HPD treats as immediately hazardous.

Is 3401 Avenue J, Brooklyn getting better or worse?

New violations are coming in faster than certifications are filed. 15 new Class C against 0 certifications filed 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 3401 Avenue J, Brooklyn?

Since September 28, 2023, certifications were filed on 2 Class C violations, all 2 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 an HPD vacate order in effect at 3401 Avenue J, Brooklyn?

Yes. HPD's vacate order for part of the building has been in effect since August 24, 2026. Reason on the order: fire damage. A vacate order requires all or part of a building to be emptied for the reason on the order, and it stays in effect until HPD rescinds it. HPD Online shows whether an order has been rescinded since.

Does 3401 Avenue J, Brooklyn have active DOB violations?

Yes. 10 active DOB violations, most of them for low-pressure boilers. The newest was issued September 23, 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.

Has DOB received complaints about 3401 Avenue J, Brooklyn?

Yes. 1 DOB complaint in the last 12 months. It was filed September 17, 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 is the ENERGY STAR score for 3401 Avenue J, Brooklyn?

ENERGY STAR score 42 for 2024, against a median of 67 for Multifamily Housing that year. Buildings over 25,000 square feet report their energy use to the city every year under Local Law 84. The ENERGY STAR score runs from 1 to 100 and compares a building with similar ones nationwide; 50 is the national median. The score is the one the city publishes, and this page never estimates a Local Law 97 emissions penalty. A lot that reported several properties in one year is not scored here.

Is 3401 Avenue J, 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.

Is 3401 Avenue J, Brooklyn rent stabilized?

The building has rent-stabilized apartments on its 2024 registration. That comes from the Rent Guidelines Board's list of buildings with at least one stabilized apartment registered that year. Buildings that registered late are left off, and a 421-a or J-51 building can leave stabilization when its tax benefit ends. A particular apartment's status is for NYS HCR to say.

When was 3401 Avenue J, Brooklyn built?

The city's record gives 1930 as the year 3401 Avenue J, 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 6 floors.

How many apartments does 3401 Avenue J, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 59 residential units at 3401 Avenue J, 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 vacate orders, DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, Local Law 84 energy reports, 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 HPD vacate orders, DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, Local Law 84 energy reports, 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.
