Is 937 Jefferson Avenue, Brooklyn getting better or worse?

Certifications are being filed faster than new violations come in. 60 certifications filed against 13 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 937 Jefferson Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 20 Class C violations: 11 by the original certify-by date, 9 after it. 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 937 Jefferson Avenue, Brooklyn have active DOB violations?

Yes. 11 active DOB violations, most of them for boiler filings under Local Law 62/91. The newest was issued May 15, 2014. 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 937 Jefferson Avenue, Brooklyn?

Yes. 2 DOB complaints in the 12 months to September 25, 2026. The newest was filed August 13, 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.

When was the boiler at 937 Jefferson Avenue, Brooklyn last inspected?

On April 8, 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 937 Jefferson Avenue, Brooklyn last file its bedbug report?

On December 5, 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 937 Jefferson 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 937 Jefferson Avenue, Brooklyn built?

The city's record gives 1905 as the year 937 Jefferson 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 4 floors.

How many apartments does 937 Jefferson Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 8 residential units at 937 Jefferson 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 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, DOB complaints, the Rent Guidelines Board's stabilized-building lists, 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.
