How does BuildingCensus know UNILAB CORP is at these addresses?

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.

Data provenance — public records only

  • Los Angeles County — County Assessor annual roll (use codes, areas, values; California law redacts owner names from bulk data) and the city Office of Finance active-business registry, whose addresses carry floor and suite numbers.

Every fact on this page is drawn from the government records above — no listing sites, no scraped platforms, no third-party images. Facts from public records are uncopyrightable; each tenancy row carries its source and match confidence. Records can lag reality — a business-tax receipt or registration at an address is evidence of occupancy, not a lease confirmation.
