When were certifications filed on Class C violations at 100 East 51 Street, Brooklyn?
Since September 28, 2023, certifications were filed on 7 Class C violations, all 7 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.

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 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.
Sources. HPD housing violations and OATH/ECB hearing results, plus 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.
