Who runs this map
This is a statewide map, not a county site. Washington Current Parcels layer (ArcGIS Map Viewer) covers parcels across Washington, and Grant County is one part of it. Statewide parcel layers are usually stitched together from county files, so the newest splits or sales may show up on the county's own records first. Our October 2026 check found the map open to the public, with no account or payment needed.

- Click a lot to read its details.
- For deeds, taxes or official copies, take the parcel number to the county's own offices.
