Which floors show activity
Floors 16-30 show no business on record — 15 unbroken floors, the longest such stretch here. Also quiet: 6-14, 33-39, 1-4, 46-49. That is where the public record shows nobody, in blocks — a place to start asking, not a listing.

Floors are read from suite numbers on Miami-Dade business-tax receipts (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.
Recorded transfers — county roll + state sale file
Sale history
| Recorded | Price | Qualification | Source | Instrument |
|---|---|---|---|---|
| Sep 2021 | $465,000,000 | not rated | County roll | — |
| Jul 2016 | $387,000,000 | not rated | County roll | — |
Prices are the consideration the documentary stamps indicate, as recorded by Miami-Dade County. A qualification code is the property appraiser's judgement of whether a transfer was arm's length; the state publishes it only for the current roll period, so older transfers appear unrated rather than assumed clean. Whether a building is on the market today, and at what price, is not a public record and is not shown here — asking prices, listings and lease terms live in private commercial databases.

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.
