Questions about this building

Does 921 Montgomery Street, Brooklyn have open violations?

Yes. 921 Montgomery Street, Brooklyn had 27 open violations on September 27, 2026: 27 from HPD. 10 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 26 years, since June 19, 2000.

Is 921 Montgomery Street, Brooklyn getting better or worse?

Certifications are being filed faster than new violations come in. 23 certifications filed against 4 new Class C in the last 180 days. 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 921 Montgomery Street, Brooklyn?

Since September 29, 2023, certifications were filed on 127 Class C violations: 116 by the original certify-by date, 11 after it. HPD now marks 1 of them False Certification. 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.

Is an HPD vacate order in effect at 921 Montgomery Street, Brooklyn?

Yes. HPD's vacate order for part of the building has been in effect since June 28, 2013. Reason on the order: fire damage. A vacate order requires all or part of a building to be emptied for the reason on the order, and it stays in effect until HPD rescinds it. HPD Online shows whether an order has been rescinded since.

Does 921 Montgomery Street, Brooklyn have active DOB violations?

Yes. 5 active DOB violations, most of them for elevators. The newest was issued February 22, 2022. 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 921 Montgomery Street, Brooklyn?

Yes. 2 DOB complaints in the 12 months to September 25, 2026. The newest was filed June 30, 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 921 Montgomery Street, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since September 29, 2023: a general construction order, opened May 13, 2025, awarded for $225. 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.

What did the latest facade report find at 921 Montgomery Street, Brooklyn?

Rated SWARMP in the latest facade report, filed July 10, 2023 (inspection cycle 9). SWARMP means safe with a repair and maintenance program. Buildings taller than six stories must have their exterior walls inspected once in every inspection cycle under the city's Facade Inspection Safety Program (every five years under DOB's current rule), and each inspection report is filed with DOB as Safe, SWARMP (safe with a repair and maintenance program) or Unsafe. No Report Filed means DOB has no report for that cycle. The rating is from the latest filing and does not describe the facade today; DOB's page for the building shows anything filed since.

What is the ENERGY STAR score for 921 Montgomery Street, Brooklyn?

ENERGY STAR score 74 for 2024, against a median of 67 for Multifamily Housing that year. Buildings over 25,000 square feet report their energy use to the city every year under Local Law 84. The ENERGY STAR score runs from 1 to 100 and compares a building with similar ones nationwide; 50 is the national median. The score is the one the city publishes, and this page never estimates a Local Law 97 emissions penalty. A lot that reported several properties in one year is not scored here.

When was the boiler at 921 Montgomery Street, Brooklyn last inspected?

On May 26, 2026. 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 921 Montgomery Street, Brooklyn last file its bedbug report?

On December 2, 2025, 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 921 Montgomery Street, Brooklyn covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered under Article 321, the path for certain affordable housing and houses of worship (DOB's list, March 1, 2026). Local Law 97 sets greenhouse gas limits for most New York City buildings over 25,000 square feet, and DOB's covered buildings list says which path each building is on. The list reflects DOB's records, which owners can ask DOB to correct. This page never estimates a penalty or says whether a building complies.

Is 921 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 921 Montgomery Street, Brooklyn built?

The city's record gives 1927 as the year 921 Montgomery Street, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator apartment building with 6 floors.

How many apartments does 921 Montgomery Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 94 residential units at 921 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 HPD vacate orders, DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, HPD emergency repair orders, Local Law 84 energy reports, DOB boiler inspection reports, HPD's annual bedbug reports, DOB's Local Law 97 covered buildings list 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 HPD vacate orders, DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, HPD emergency repair orders, Local Law 84 energy reports, DOB boiler inspection reports, HPD's annual bedbug reports, DOB's Local Law 97 covered buildings list 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.
