Prices are the consideration recorded in Detroit's public property records. Where a qualification code exists it is the assessor's judgement of whether a transfer was arm's length; transfers without one appear unrated rather than assumed clean. Whether a building is on the market today, and at what price, is not a public record and is not shown here — asking prices, listings and lease terms live in private commercial databases.

Data provenance — public records only
- Detroit — City of Detroit open-data parcel roll (taxpayer names and mailing addresses, nightly), the assessor sales view with prices and counterparties, and the city's energy benchmarking ordinance datasets. The licence roll covers regulated trades only, 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.
