Questions about this building

Does 605 Grand Avenue, Brooklyn have open violations?

Yes. 605 Grand Avenue, Brooklyn had 26 open violations on September 26, 2026: 6 from OATH/ECB and 20 from HPD. 12 are Class C, the class HPD treats as immediately hazardous.

Is 605 Grand Avenue, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 12 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 605 Grand Avenue, Brooklyn?

Since September 28, 2023, certifications were filed on 2 Class C violations, all 2 after 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 605 Grand Avenue, Brooklyn have active DOB violations?

Yes. 11 active DOB violations. The newest was issued June 30, 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.

Has DOB received complaints about 605 Grand Avenue, Brooklyn?

Yes. 2 DOB complaints in the last 12 months. The newest was filed May 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 DOB work permits in effect at 605 Grand Avenue, Brooklyn?

Yes. 3 DOB work permits in effect. The latest, for General Construction work, was issued January 16, 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 605 Grand 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 605 Grand Avenue, Brooklyn built?

The city's record gives 1930 as the year 605 Grand 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 3 floors.

How many apartments does 605 Grand Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 9 residential units at 605 Grand 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, DOB complaints, 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, DOB complaints, 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.
