Floors are read from suite numbers on Houston / Harris County business records (suite 4900 → floor 49). A floor with no record is not necessarily vacant — it may be mechanical, occupied by the owner, or let to a business whose receipt carries no suite. Receipts also lag reality by months. This shows where the public record places businesses, not a rent roll or an availability report. A stretch of quiet floors is not contiguous space for rent — it is contiguous silence in the record, which is the closest thing the public record has to that question and worth exactly what it costs to check.

Data provenance — public records only

  • Houston / Harris County — Harris Central Appraisal District bulk CAMA files (owner names, mailing addresses, appraised values, and per-building net rentable area — data most counties never publish). Texas is a non-disclosure state, so no sale prices exist in any public record, and Houston issues no universal business licence, so no tenant layer is possible. 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.
