Where the parcel data comes from
This is a statewide map, not a county site. ORMAP statewide tax lot viewer (Oregon) covers parcels across Oregon, and Columbia County is one part of it. A statewide layer can trail the county's own books by weeks or months, so treat it as a fast first look rather than the final word. Our October 2026 check found the map open to the public, with no account or payment needed.
