Which floors show activity

14 of 34 floors show activityfrom 28 suite-numbered receipts

Floors 5-10 show no business on record — 6 unbroken floors, the longest such stretch here. Also quiet: 31-34, 13-15, 19-21, 2-3. 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.

Federal lease inventory — actual rent paid

Leases on public record

LeaseRentable sq ftAnnual rent$/sq ftTermOptions left
LWA00238—$519,387—Oct 2020 → Oct 2034—

From the General Services Administration's monthly lease inventory: the rent the federal government actually pays, the square feet behind it, the dates, and the renewal options remaining. A fully serviced lease includes services and utilities, so it is not comparable to a net rent. This is one tenant, not the market. Federal space is often fitted for a specific agency and leased on government terms, so treat it as a real, checkable data point rather than an asking rent for the building.

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.

Data provenance — public records only

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.
