Which floors show activity
Floors 1-2 show no business on record — 2 unbroken floors, the longest such stretch here. Also quiet: 10-11, 13-14. 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.
The building's own benchmarking filing
Energy performance
From the building's own filing under the City of Miami's benchmarking ordinance. An ENERGY STAR score of 75 or above means the building outperforms three quarters of comparable buildings nationally. It is a self-reported figure, verified by the city only to the extent the ordinance requires.

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.
