Los Angeles County office buildings — the public record

Every office-class parcel in Los Angeles County — who owns it and what the assessor values it at and which businesses the public record places inside. Built exclusively from government data: County Assessor annual roll (use codes, areas, values; California law redacts owner names from bulk data) and the city Office of Finance active-business registry, whose addresses carry floor and suite numbers. No listing sites, no scraping — every page cites its sources.

What this metro does not have yet. Owner mailing addresses are not published either, so landlord portfolios cannot be grouped the way they are in Miami. Rather than fill the gap with an inference, the sections are absent.

Derived from county business-tax suite numbers

Buildings with a floor-by-floor view

Business-tax receipts carry suite numbers, and in a tower the suite prefix is the floor. Where enough of them agree with the county roll, the building page shows which floors the public record places businesses on. It is an occupancy signal, not a vacancy report.

Building names are editorial labels for well-known towers; all facts are the county's. Assessed values are the taxable-roll figures — not market prices.

Federal lease inventory — actual rent paid

The one rent figure that is public

Across 108 active federal office leases in Miami-Dade, the median rent is $42.49 per rentable square foot per year, with the middle half between $36 and $52. Asking rents are proprietary; the federal government publishes what it actually pays, lease by lease, and those leases appear on the building pages they belong to. One tenant is not a market — federal space is often agency-fitted and leased on government terms.

Data provenance — public records only

Miami-Dade County Property Appraiser — assessment roll — Parcel identity, site address, recorded owner, use code, areas, year built and assessed values, via the county's public GIS services (MD_LandInformation, PaGis layer).
Miami-Dade County Local Business Tax roll — Business-tax receipts: business name, premises address (incl. suite/floor), account status and start date, via the county's public GIS services.
Florida Division of Corporations (Sunbiz) — corporate data file — Registered entities: document number, status, filing date, registered agent and principal address, from the state's public quarterly data file.
Miami-Dade County Property Appraiser — recorded sale — The last recorded transfer price and date for the parcel, from the county's public property point view.
Florida Department of Revenue — Sale Data File — Every transfer in the current roll period with the property appraiser's sale qualification code, vacant/improved code, multi-parcel flag and the clerk's recording reference.
U.S. General Services Administration — lease inventory — Active federal leases published monthly: annual rent actually paid, rentable square feet, effective and expiration dates, termination right, renewal options remaining and the lessor's name.

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.
