- 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.
