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's housing court cases, Local Law 84 energy 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.
