That window ends October 10, 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 129 Carlton Avenue, Brooklyn?

Since October 12, 2023, certifications were filed on 3 Class C violations, all 3 by the original certify-by date. HPD now marks 1 of them Invalid Certification. 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 129 Carlton Avenue, 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.

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

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 DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOF's exemption rolls, DOB boiler inspection reports, HPD's annual bedbug reports and the city's PLUTO tax-lot file. This page is current through October 10, 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 DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOF's exemption rolls, DOB boiler inspection reports, HPD's annual bedbug reports 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.
