Questions about this building

Does 245 Hawthorne Street, Brooklyn have open violations?

Yes. 245 Hawthorne Street, Brooklyn had 129 open violations on September 27, 2026: 3 from OATH/ECB and 126 from HPD. 72 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 14 years, since May 15, 2012.

Is 245 Hawthorne Street, Brooklyn getting better or worse?

Certifications are being filed faster than new violations come in. 36 certifications filed against 17 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 245 Hawthorne Street, Brooklyn?

Since September 29, 2023, certifications were filed on 200 Class C violations: 191 by the original certify-by date, 9 after it. 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.

Is 245 Hawthorne Street, Brooklyn in HPD's Alternative Enforcement Program?

Yes. In HPD's Alternative Enforcement Program since February 2, 2026. HPD puts a group of buildings with serious, long-running violations into the program each year. While a building is in it, HPD can make repairs itself and charge the cost to the property, and the building stays in until HPD discharges it.

Does 245 Hawthorne Street, Brooklyn have an OATH hearing coming up?

Yes. 3 hearings scheduled on DOB summonses, the first on November 25, 2026. 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 245 Hawthorne Street, Brooklyn have active DOB violations?

Yes. 6 active DOB violations, most of them for construction. The newest was issued September 9, 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.

Has DOB received complaints about 245 Hawthorne Street, Brooklyn?

Yes. 5 DOB complaints in the 12 months to September 25, 2026. The newest was filed September 23, 2026. 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.

Are any HPD emergency repair orders at 245 Hawthorne Street, Brooklyn marked completed?

Yes. 7 completed HPD emergency repair orders since September 29, 2023, awarded for $16,941 in total. The most recent of the 7, a general construction order, was opened October 2, 2025. 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 245 Hawthorne Street, Brooklyn?

ENERGY STAR score 25 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 245 Hawthorne Street, Brooklyn last inspected?

On February 3, 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 245 Hawthorne Street, Brooklyn last file its bedbug report?

On December 3, 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 245 Hawthorne Street, 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 245 Hawthorne 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 245 Hawthorne Street, Brooklyn built?

The city's record gives 1941 as the year 245 Hawthorne Street, 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 245 Hawthorne Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 78 residential units at 245 Hawthorne 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 HPD's Alternative Enforcement Program list, OATH hearing dates, DOB violations, DOB complaints, 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 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 HPD's Alternative Enforcement Program list, OATH hearing dates, DOB violations, DOB complaints, 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.
