Questions about this building

Does 2450 Nostrand Avenue, Brooklyn have open violations?

Yes. 2450 Nostrand Avenue, Brooklyn had 16 open violations on October 10, 2026: 16 from HPD. 10 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 6 years, since October 2, 2020.

Is 2450 Nostrand Avenue, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 10 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 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 2450 Nostrand Avenue, Brooklyn?

Since October 12, 2023, certifications were filed on 9 Class C violations, all 9 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 2450 Nostrand Avenue, Brooklyn have active DOB violations?

Yes. 4 active DOB violations, most of them for elevator affirmations of correction. The newest was issued January 26, 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.

Has 2450 Nostrand Avenue, Brooklyn been in housing court?

Yes. 2 housing court cases here since 2009, most of them tenant actions. 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.

Are any HPD emergency repair orders at 2450 Nostrand Avenue, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since October 12, 2023: a general construction order, opened June 6, 2026, awarded for $427. 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 is the ENERGY STAR score for 2450 Nostrand Avenue, Brooklyn?

ENERGY STAR score 45 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 2450 Nostrand Avenue, Brooklyn last inspected?

On September 9, 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 2450 Nostrand Avenue, Brooklyn last file its bedbug report?

On May 1, 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 2450 Nostrand Avenue, 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 2450 Nostrand 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 2450 Nostrand Avenue, Brooklyn built?

The city's record gives 1955 as the year 2450 Nostrand Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator building with 6 floors.

How many apartments does 2450 Nostrand Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 50 residential units at 2450 Nostrand 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, the Rent Guidelines Board's stabilized-building lists, DOB NOW work permits, 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 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, the Rent Guidelines Board's stabilized-building lists, DOB NOW work permits, 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.
