Questions about this building

Is 42 Hawthorne Street, Brooklyn getting better or worse?
Open violations are sitting, with little movement either way. 14 open Class C, with nothing filed or new in the last 180 days. That window ends September 26, 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 42 Hawthorne Street, Brooklyn?
Since September 28, 2023, certifications were filed on 11 Class C violations: 8 by the original certify-by date, 3 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.
Does 42 Hawthorne Street, Brooklyn have active DOB violations?
Yes. 15 active DOB violations, most of them for boiler filings under Local Law 62/91. The newest was 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.
Is 42 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.

When was 42 Hawthorne Street, Brooklyn built?

Where do these numbers come from?

It also draws on DOB violations, the Rent Guidelines Board's stabilized-building lists and the city's PLUTO tax-lot file. This page is current through September 26, 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.
