From New York City's own data: HPD housing violations and OATH/ECB hearing results, read whole rather than sampled. It also draws on OATH/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, 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 OATH/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, 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.
