About the official source
This is a statewide map, not a county site. ORMAP statewide tax lot viewer (Oregon) covers parcels across Oregon, and Clatsop 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. As of our October 2026 test, anyone could open it without signing in or paying.
Finding a property on this statewide map
- Open ORMAP statewide tax lot viewer (Oregon) in a new tab and zoom to Clatsop County (around Astoria).
- Type a street address into the search box, or click directly on a parcel.
- Review the parcel attributes; field names vary by state.
- Confirm anything important with the county assessor, since the statewide layer is a compiled copy.
If an address search comes up empty, try the parcel number from a tax bill or deed instead, or click the lot on the map.

A note on accuracy
Treat the map as a guide, not a boundary survey: parcel outlines are often shifted a bit from the real corners. A licensed surveyor settles exact lines.
