Questions about this building

Does 280 East 91 Street, Brooklyn have open violations?

Yes. 280 East 91 Street, Brooklyn had 26 open violations on September 26, 2026: 26 from HPD. 11 are Class C, the class HPD treats as immediately hazardous.

Is 280 East 91 Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 11 open Class C, with 3 certifications filed and 0 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.

When were certifications filed on Class C violations at 280 East 91 Street, Brooklyn?

Since September 28, 2023, certifications were filed on 13 Class C violations, all 13 by the original certify-by date. HPD now marks 1 of them Invalid 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.

Does 280 East 91 Street, Brooklyn have active DOB violations?

Yes. 9 active DOB violations. The newest was issued November 14, 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.

What is the ENERGY STAR score for 280 East 91 Street, Brooklyn?

ENERGY STAR score 40 for 2023, against a median of 66 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.

Is 280 East 91 Street, Brooklyn covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered from 2035 as an income-restricted building (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.

When was 280 East 91 Street, Brooklyn built?

The city's record gives 1920 as the year 280 East 91 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 280 East 91 Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 31 residential units at 280 East 91 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, Local Law 84 energy reports, DOB's Local Law 97 covered buildings list 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, Local Law 84 energy 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.
