Questions about this building

Does 20 Bay 34 Street, Brooklyn have open violations?

Yes. 20 Bay 34 Street, Brooklyn had 22 open violations on September 26, 2026: 22 from HPD. 11 are Class C, the class HPD treats as immediately hazardous.

Is 20 Bay 34 Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 11 open Class C, with nothing filed or new 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 20 Bay 34 Street, Brooklyn?

Since September 28, 2023, certifications were filed on 4 Class C violations, all 4 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 20 Bay 34 Street, Brooklyn have active DOB violations?

Yes. 4 active DOB violations, most of them for low-pressure boilers. The newest was issued June 20, 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 DOB work permits in effect at 20 Bay 34 Street, Brooklyn?

Yes. 2 DOB work permits in effect. The latest, for Boiler Equipment work, was issued March 10, 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.

Is 20 Bay 34 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 20 Bay 34 Street, Brooklyn built?

The city's record gives 1926 as the year 20 Bay 34 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 20 Bay 34 Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 19 residential units at 20 Bay 34 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, DOB NOW work permits 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, DOB NOW work permits 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.
