Which floors show activity

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.

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.
