Questions about this building

Does 3601 Neptune Avenue, Brooklyn have open violations?

Yes. 3601 Neptune Avenue, Brooklyn had 50 open violations on October 10, 2026: 50 from HPD. 24 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 6 years, since August 24, 2020.

Is 3601 Neptune Avenue, Brooklyn getting better or worse?

Certifications are being filed about as fast as new violations come in. 8 certifications filed and 8 new Class C in the last 180 days, neither far ahead. That window ends October 10, 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 3601 Neptune Avenue, Brooklyn?

Since October 12, 2023, certifications were filed on 11 Class C violations, all 11 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.

Has 3601 Neptune Avenue, Brooklyn been in housing court?

Yes. 5 housing court cases here since 2008, most of them tenant actions. 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 3601 Neptune Avenue, Brooklyn?

Yes. 1 DOB complaint in the 12 months to September 25, 2026. It was filed September 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.

Are any HPD emergency repair orders at 3601 Neptune Avenue, Brooklyn marked completed?

Yes. 3 completed HPD emergency repair orders since October 12, 2023, awarded for $2,685 in total. The most recent of the 3, a general construction order, was opened July 10, 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.

Are any DOB work permits in effect at 3601 Neptune Avenue, Brooklyn?

Yes. 1 DOB work permit in effect, for Suspended Scaffold work, issued August 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.

What is the ENERGY STAR score for 3601 Neptune Avenue, Brooklyn?

ENERGY STAR score 9 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.

When did 3601 Neptune Avenue, Brooklyn last file its bedbug report?

On December 23, 2025, 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.

Is 3601 Neptune 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.

Does 3601 Neptune Avenue, Brooklyn have a property tax exemption?

The building has a Mitchell-Lama tax exemption on DOF's 2026/27 roll. An exemption lowers a property's tax bill by reducing its assessed value.

When was 3601 Neptune Avenue, Brooklyn built?

The city's record gives 1975 as the year 3601 Neptune Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator building with 24 floors.

How many apartments does 3601 Neptune Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 338 residential units at 3601 Neptune 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/ECB summonses from DOB and FDNY, HPD's housing court cases, DOB complaints, DOF's exemption rolls, DOB NOW work permits, HPD emergency repair orders, Local Law 84 energy reports, HPD's annual bedbug reports, DOB's Local Law 97 covered buildings list and the city's PLUTO tax-lot file. This page is current through October 10, 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/ECB summonses from DOB and FDNY, HPD's housing court cases, DOB complaints, DOF's exemption rolls, DOB NOW work permits, HPD emergency repair orders, Local Law 84 energy reports, HPD's annual bedbug 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.
