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.
