Data provenance — public records only
- Denver — City and County of Denver open-data parcels (owner names, mailing addresses, office classes, commercial areas), the recorded sales and transfers table with prices and counterparties, and Energize Denver benchmarking. The city's licence roll covers regulated trades only and carries no premises addresses, so no tenant layer is possible.
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.
