Questions about this building

Does 1974 51 Street, Brooklyn have open violations?

Yes. 1974 51 Street, Brooklyn had 7 open violations on October 10, 2026: 7 from HPD. 3 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 7 years, since September 11, 2019.

Is 1974 51 Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 3 open Class C, with 5 certifications filed and 1 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 1974 51 Street, Brooklyn?

Since October 12, 2023, certifications were filed on 18 Class C violations, all 18 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 1974 51 Street, Brooklyn have active DOB violations?

Yes. 5 active DOB violations. The newest was issued June 20, 2023. 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.

Are any HPD emergency repair orders at 1974 51 Street, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since October 12, 2023: a general construction order, opened October 29, 2024, awarded for $2,260. 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 1974 51 Street, Brooklyn?

ENERGY STAR score 64 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 1974 51 Street, Brooklyn last inspected?

On April 28, 2025. 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 1974 51 Street, Brooklyn last file its bedbug report?

On December 12, 2024, for the year to October 31, 2024. 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 1974 51 Street, Brooklyn covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered from 2026 as a rent-regulated 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.

Is 1974 51 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 1974 51 Street, Brooklyn built?

The city's record gives 1928 as the year 1974 51 Street, 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 4 floors.

How many apartments does 1974 51 Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 47 residential units at 1974 51 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 OATH/ECB summonses from DOB and FDNY, DOB violations, the Rent Guidelines Board's stabilized-building lists, 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, the Rent Guidelines Board's stabilized-building lists, 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.
