DOB NOW: Certificate of Occupancy

Official daily-updated NYC Open Data dataset of certificates of occupancy issued through DOB NOW from March 2021 onward. Records resolve by BIN, street address, borough/block/lot and BBL, and publish DOB job filing, certificate application and C of O identifiers, request and issuance dates, issued status, filing type and sequence, dwelling-unit count, and geographic reference fields. This is an issued-certificate index: it does not publish approved use, occupancy group, floor/area schedules, effective or expiration date, document URL, or an explicit current/superseded flag. Absence must not be interpreted as evidence of present use, illegal occupancy, safety, or noncompliance.
