Building and Safety Certificate of Occupancy

Address/APN-resolved certificate rows emit floor area under zoning and building-code definitions, residential dwelling-unit count, number of stories, approved occupancy where populated, and permit/work facts with issue and status dates. These are useful permit-vintage building facts, not a complete physical-configuration inventory; the product does not provide year built, roof, systems, a building count, or a structure identifier for multi-structure disambiguation.

For a covered Los Angeles certificate row, the official dataset emits the structure's approved-use occupancy where populated, CofO number and issue date, latest certificate status and status date, address and assessor-parcel keys, and a dated source vintage. This supplies dated recorded building occupancy and certificate-status evidence, not proof of present operations or controlling current legal occupancy; 82.89% of checked rows lack occupancy and no successor-certificate identifier is emitted.

Assessor-parcel keyed certificate rows emit floor area, residential dwelling-unit count, stories, work description, valuation, and related permit and certificate dates/status. These provide partial permit-vintage parcel-improvement configuration, not a complete current assessor inventory; building count, age, broad construction attributes, and multi-structure disambiguation are absent.

Assessor book-page-parcel keyed certificate rows emit the raw occupancy value defined by LADBS as approved use for the structure, together with CofO issue date, latest status, status date, and source vintage. This is useful permit/certificate-associated occupancy classification for the parcel record, not parcel-wide proof of every structure's use, present operations, or current controlling occupancy; occupancy is null in 82.89% of checked rows.

Parcel/address-resolved certificate rows publish the related PCIS and old permit identifiers, permit type, subtype and category, project and event codes, permit issue date, work description, and CofO status and status date. This is supplemental evidence of work that reached an issued-permit/certificate record, not a complete permit lifecycle or complete permit history.
