Questions about this building

Does 400 Herkimer Street, Brooklyn have open violations?

Yes. 400 Herkimer Street, Brooklyn had 137 open violations on September 27, 2026: 10 from OATH/ECB and 127 from HPD. 50 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 35 years, since January 24, 1991.

Is 400 Herkimer Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 50 open Class C, with nothing filed or new in the last 180 days. 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 400 Herkimer Street, Brooklyn?

Since September 29, 2023, certifications were filed on 123 Class C violations, all 123 by the original certify-by date. HPD now marks 4 of them False Certification and 3 Invalid Certification. 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 400 Herkimer Street, Brooklyn have an OATH hearing coming up?

Yes. A hearing on a DOB summons is set for October 14, 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 400 Herkimer Street, Brooklyn have active DOB violations?

Yes. 6 active DOB violations, most of them for low-pressure boilers. The newest was issued July 22, 2026. 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 400 Herkimer Street, Brooklyn in housing court?

Yes. 2 open housing court cases, most of them tenant actions. The newest opened April 13, 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 400 Herkimer Street, Brooklyn?

Yes. 7 DOB complaints in the 12 months to September 25, 2026. The newest was filed September 14, 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 400 Herkimer Street, Brooklyn marked completed?

Yes. 7 completed HPD emergency repair orders since September 29, 2023, awarded for $6,932 in total. The most recent of the 7, a general construction order, was opened May 15, 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.

What did the latest facade report find at 400 Herkimer Street, Brooklyn?

No Report Filed for 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.

What is the ENERGY STAR score for 400 Herkimer Street, Brooklyn?

ENERGY STAR score 95 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 was the boiler at 400 Herkimer Street, Brooklyn last inspected?

It has 2 boilers, both inspected in 2026, the latest on July 10. DOB requires a boiler in a building with 6 or more apartments to be inspected once every calendar year, with the report filed within 14 days of the inspection. Low-pressure boilers in residential buildings with 5 or fewer apartments are exempt.

Is 400 Herkimer Street, 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 400 Herkimer Street, 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 400 Herkimer Street, Brooklyn built?

The city's record gives 1965 as the year 400 Herkimer Street, 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 400 Herkimer Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 154 residential units at 400 Herkimer Street, 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, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, HPD emergency repair orders, Local Law 84 energy reports, DOB boiler inspection reports, DOB's Local Law 97 covered buildings list 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, DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, HPD emergency repair orders, Local Law 84 energy reports, DOB boiler inspection 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.
