Is 307 Troutman Street, Brooklyn getting better or worse?
Certifications are being filed faster than new violations come in. 9 certifications filed against 2 new Class C 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 307 Troutman Street, Brooklyn?
Since September 28, 2023, certifications were filed on 25 Class C violations: 24 by the original certify-by date, 1 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 307 Troutman Street, Brooklyn have active DOB violations?
Yes. 1 active DOB violation, issued August 16, 1993. 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.
Does 307 Troutman Street, Brooklyn have a certificate of occupancy?
Its latest certificate of occupancy is a final one, issued June 17, 2021. A certificate of occupancy says how a building may be used and occupied. A temporary one lets people move in while work finishes and has to be renewed until DOB issues the final one. DOB's records here start in July 2012, so an older certificate may not show.
