Questions about this building

Does 21 Judge Street, Brooklyn have open violations?

Yes. 21 Judge Street, Brooklyn had 26 open violations on September 26, 2026: 25 from HPD and 1 from OATH/ECB. 10 are Class C, the class HPD treats as immediately hazardous.

Is 21 Judge Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 10 open Class C, with 0 certifications filed and 2 new Class C in the last 180 days, too few to call a direction. That window ends September 26, 2026. It compares certifications filed with new Class C violations, and it describes what happened, not what anyone intends.

Does 21 Judge Street, Brooklyn have an OATH hearing coming up?

Yes. A hearing on a DOB summons is set for April 16, 2027. 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.

Has DOB received complaints about 21 Judge Street, Brooklyn?

Yes. 1 DOB complaint in the last 12 months. It was filed May 23, 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 21 Judge Street, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since September 28, 2023: a general construction order, opened September 18, 2025, awarded for $600. 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.

Does 21 Judge Street, Brooklyn have a certificate of occupancy?

Its latest certificate of occupancy is a final one, issued July 24, 2014. A certificate of occupancy says how a building may be used and occupied. A temporary one lets people move in while work finishes and has to be renewed until DOB issues the final one. DOB's records here start in July 2012, so an older certificate may not show.

Is 21 Judge 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 21 Judge Street, Brooklyn built?

The city's record gives 2009 as the year 21 Judge 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 21 Judge Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 15 residential units at 21 Judge 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 complaints, the Rent Guidelines Board's stabilized-building lists, DOB certificates of occupancy, 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 OATH hearing dates, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB certificates of occupancy, 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.
