Where do these numbers come from?

It also draws on DOB violations, HPD emergency repair orders and the city's PLUTO tax-lot file. This page is current through September 27, 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.

The city's own pages can show more, never fewer.
