Each location is a business record whose premises address was matched to a county office parcel (record types on this page: LA business tax registry). The match method and confidence are shown on every row.
A record at an address is evidence that the business operates there, not a lease: records lag moves by months, and businesses without a local record at an address do not appear.

Facts from public records are uncopyrightable; each tenancy row carries its source and match confidence.
