Questions about this building

Does 599 Flatbush Avenue, Brooklyn have open violations?

Yes. 599 Flatbush Avenue, Brooklyn had 64 open violations on September 27, 2026: 54 from HPD and 10 from OATH/ECB. 24 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 10 years, since August 31, 2016.

Is 599 Flatbush Avenue, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 24 open Class C, with 3 certifications filed and 1 new Class C in the last 180 days, too few to call a direction. 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 599 Flatbush Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 39 Class C violations, all 39 by the original certify-by date. HPD now marks 1 of them 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 599 Flatbush Avenue, Brooklyn have active DOB violations?

Yes. 7 active DOB violations. The newest was issued February 12, 2025. 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 599 Flatbush Avenue, Brooklyn in housing court?

Yes. 2 open housing court cases. The newest opened July 30, 2025. 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 599 Flatbush Avenue, Brooklyn?

Yes. 3 DOB complaints, 2 of them conversion complaints, in the 12 months to September 25, 2026. The newest was filed March 12, 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 599 Flatbush Avenue, Brooklyn marked completed?

Yes. 2 completed HPD emergency repair orders since September 29, 2023, awarded for $2,545 in total. The most recent of the 2, a general construction order, was opened April 1, 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.

When did 599 Flatbush Avenue, Brooklyn last file its bedbug report?

On December 25, 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 599 Flatbush Avenue, 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 599 Flatbush Avenue, Brooklyn built?

The city's record gives 1931 as the year 599 Flatbush Avenue, Brooklyn 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 4 floors.

How many apartments does 599 Flatbush Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 11 residential units at 599 Flatbush 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 DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, 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 DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, 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.
