Data provenance — public records only
- Dallas / Dallas County — Dallas Central Appraisal District certified bundle (owner names, mailing addresses, building classes, gross and net-lease areas, values). Texas non-disclosure means no sale prices exist in any public record, and no universal business licence means no tenant layer. A partial tenant layer comes from the Texas Comptroller's active sales-tax permit roll: suite-level business locations, but only firms with taxable sales — professional services without them do not appear.
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.
