Who runs this map
This map is published by or for San Diego County itself, so it reflects the local parcel layer rather than a third-party copy. Our October 2026 check found the map open to the public, with no account or payment needed.
Searching for a parcel, step by step
- Open the official link; it loads in ArcGIS Map Viewer, Esri's standard web map.
- Zoom to the area you want, or enter an address in the search field.
- Select a parcel to see its pop-up details.
- Try the Basemap gallery for satellite views, and the Measure tool if you want a rough distance or area.
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.

Maps vs. surveys
Keep in mind that a GIS parcel layer is a tax map, not a survey. For exact boundaries, look at the recorded deed and plat or hire a licensed land surveyor.
