Floors are read from suite numbers on San Francisco business records (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

Data provenance — public records only
- San Francisco — Assessor secured roll (use classes, stories, areas, assessed values — California law excludes owner names from open data, and no bulk sale-price source exists), the universal registered-business roll with suite-level addresses, and current energy benchmarking joined by parcel.
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.
