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 HPD vacate orders, OATH/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, DOB complaints, the city's PLUTO tax-lot file and DOF's property sales records. 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 records are the authority on what is open today.

Sources. HPD housing violations and OATH/ECB hearing results, plus HPD vacate orders, OATH/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, DOB complaints, the city's PLUTO tax-lot file and DOF's property sales records. 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.
