Questions about this building

Does 250 Clarkson Avenue, Brooklyn have open violations?

Yes. 250 Clarkson Avenue, Brooklyn had 36 open violations on September 27, 2026: 34 from HPD and 2 from OATH/ECB. 14 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 19 years, since May 24, 2007.

Is 250 Clarkson Avenue, Brooklyn getting better or worse?

Certifications are being filed faster than new violations come in. 13 certifications filed against 6 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 250 Clarkson Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 48 Class C violations, all 48 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 250 Clarkson Avenue, Brooklyn have an OATH hearing coming up?

Yes. 2 hearings scheduled on DOB summonses, the first on February 8, 2027. DOB summonses are heard at OATH, the city's hearings office, and OATH can move a hearing to a later date. When nobody shows up, the summons is decided by default, the costliest way one ends.

Does 250 Clarkson Avenue, Brooklyn have active DOB violations?

Yes. 3 active DOB violations, most of them for construction. The newest was issued December 1, 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.

Has DOB received complaints about 250 Clarkson Avenue, Brooklyn?

Yes. 1 DOB complaint in the 12 months to September 25, 2026. It was filed November 8, 2025. 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.

What is the ENERGY STAR score for 250 Clarkson Avenue, Brooklyn?

ENERGY STAR score 14 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 250 Clarkson Avenue, Brooklyn last inspected?

On July 28, 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 250 Clarkson Avenue, Brooklyn last file its bedbug report?

On December 15, 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 250 Clarkson 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 250 Clarkson 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 250 Clarkson Avenue, Brooklyn built?

The city's record gives 1962 as the year 250 Clarkson Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator apartment building with 6 floors.

How many apartments does 250 Clarkson Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 100 residential units at 250 Clarkson 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 hearing dates, DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, 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 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 OATH hearing dates, DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, 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.
