Questions about this building

Does 364 Sumpter Street, Brooklyn have open violations?

Yes. 364 Sumpter Street, Brooklyn had 34 open violations on September 26, 2026: 34 from HPD. 10 are Class C, the class HPD treats as immediately hazardous.

Is 364 Sumpter Street, Brooklyn getting better or worse?

Certifications are being filed about as fast as new violations come in. 7 certifications filed and 5 new Class C in the last 180 days, neither far ahead. 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 364 Sumpter Street, Brooklyn?

Since September 28, 2023, certifications were filed on 7 Class C violations, all 7 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 364 Sumpter Street, Brooklyn have active DOB violations?

Yes. 2 active DOB violations. The newest was issued June 30, 2023. 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.

Are any HPD emergency repair orders at 364 Sumpter Street, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since September 28, 2023: a general construction order, opened May 22, 2026, awarded for $1,987. 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.

Is 364 Sumpter 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 364 Sumpter Street, Brooklyn built?

The city's record gives 1923 as the year 364 Sumpter Street, 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 364 Sumpter Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 20 residential units at 364 Sumpter 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 DOB violations, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders 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 DOB violations, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders 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.
