Certificate of occupancy status

Official City of Los Angeles open-data product exposing LADBS Certificate of Occupancy records through dataset 3f9m-afei, an anonymous SODA API, and downloadable full files. Rows carry CofO number, issue date, latest certificate status and status-effective date; assessor book/page/parcel, legal-description and street-address keys; the related PCIS permit; permit and building facts; and, where populated, an `occupancy` value explicitly defined as the approved use for the structure. Public metadata identifies LADBS, official provenance, CC0 1.0 dedication, a weekly committed refresh, and data updated 2026-08-17; the checked live data contained 128,551 rows with CofO issue dates from 2005-01-26 through 2026-08-14. This is a certificate-record dataset, not proof of present operations: 82.89% of checked rows have null occupancy, no separate certificate-type or successor identifier is emitted, and current interpretation must be pinned to `cofo_issue_date`, `status_date`, `latest_status`, and the dataset-level source vintage.

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approved use, occupancy group, floor/area schedules, effective or expiration date, document URL, or an explicit current/superseded flag.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.
