New violations are coming in faster than certifications are filed. 12 new Class C against 0 certifications filed 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 247 Hart Street, Brooklyn?
Since September 28, 2023, certifications were filed on 8 Class C violations, all 8 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 247 Hart Street, Brooklyn have active DOB violations?
Yes. 1 active DOB violation, issued July 25, 1994. 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 247 Hart Street, Brooklyn marked completed?
Yes. 2 completed HPD emergency repair orders since September 28, 2023, awarded for $1,020 in total. The most recent of the 2, a general construction order, was opened May 27, 2026. 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.
Is 247 Hart Street, Brooklyn rent stabilized?
