Questions about this building

Does 346 Montgomery Street, Brooklyn have open violations?

Yes. 346 Montgomery Street, Brooklyn had 97 open violations on September 27, 2026: 95 from HPD and 2 from OATH/ECB. 25 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 15 years, since September 6, 2011.

Is 346 Montgomery Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 25 open Class C, with 0 certifications filed and 6 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 346 Montgomery Street, Brooklyn?

Since September 29, 2023, certifications were filed on 2 Class C violations, all 2 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 346 Montgomery Street, Brooklyn have active DOB violations?

Yes. 1 active DOB violation, issued May 2, 2018. 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 346 Montgomery Street, Brooklyn in housing court?

Yes. 2 open housing court cases. The newest opened July 15, 2026. 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 346 Montgomery Street, Brooklyn?

Yes. 1 DOB complaint in the 12 months to September 25, 2026. It was filed March 16, 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 346 Montgomery Street, Brooklyn marked completed?

Yes. 5 completed HPD emergency repair orders since September 29, 2023, awarded for $7,326 in total. The most recent of the 5, a general construction order, was opened August 28, 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 was the boiler at 346 Montgomery Street, Brooklyn last inspected?

On November 26, 2025. DOB requires a boiler in a building with 6 or more apartments to be inspected once every calendar year, with the report filed within 14 days of the inspection. Low-pressure boilers in residential buildings with 5 or fewer apartments are exempt.

When did 346 Montgomery Street, Brooklyn last file its bedbug report?

On May 12, 2026, 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 346 Montgomery 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 346 Montgomery Street, Brooklyn built?

The city's record gives 1923 as the year 346 Montgomery 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 346 Montgomery Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 24 residential units at 346 Montgomery 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, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, DOB boiler inspection reports, 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, DOB boiler inspection reports, 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.
