Questions about this building

Does 331 Lexington Avenue, Brooklyn have open violations?

Yes. 331 Lexington Avenue, Brooklyn had 9 open violations on October 10, 2026: 9 from HPD. 3 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 5 years, since April 20, 2021.

Is 331 Lexington Avenue, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 3 open Class C, with 2 certifications filed and 0 new Class C in the last 180 days, too few to call a direction. That window ends October 10, 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 331 Lexington Avenue, Brooklyn?

Since October 12, 2023, certifications were filed on 4 Class C violations, all 4 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 331 Lexington Avenue, Brooklyn have active DOB violations?

Yes. 1 active DOB violation, issued September 23, 2024. 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 331 Lexington Avenue, Brooklyn been in housing court?

Yes. 2 housing court cases here since 2018. 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.

What is the ENERGY STAR score for 331 Lexington Avenue, Brooklyn?

ENERGY STAR score 98 for 2022, against a median of 65 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.

Does 331 Lexington Avenue, Brooklyn have a property tax exemption?

The building has an NYC Housing Authority tax exemption on DOF's 2026/27 roll. An exemption lowers a property's tax bill by reducing its assessed value.

When was 331 Lexington Avenue, Brooklyn built?

The city's record gives 1994 as the year 331 Lexington Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up building with 3 floors.

How many apartments does 331 Lexington Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 48 residential units at 331 Lexington 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 OATH/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, DOF's exemption rolls, DOB NOW work permits, Local Law 84 energy reports and the city's PLUTO tax-lot file. This page is current through October 10, 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/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, DOF's exemption rolls, DOB NOW work permits, Local Law 84 energy 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.
