Permits come from Miami-Dade County, with job cost and square footage added from the City of Miami's file where the building sits in the city. Arrivals and departures are business-tax receipts opened and closed at this address. None of this is an availability listing. A permit means work was authorised, not that space is for rent, and a closed receipt can mean a business moved, renamed or simply stopped renewing. It is the record that runs ahead of a listing, which is the only part of "what is coming available" that is public at all.
