Who runs this map

This map is published by or for Somerset County itself, so it reflects the local parcel layer rather than a third-party copy. When we tested the link in October 2026 it opened with no login and no fee.

Finding a property on this map

  1. Open the link. This viewer is an ArcGIS Experience Builder app, so its layout is custom to the publisher.
  2. Look for a search box or search widget and type in a street address or parcel ID.
  3. Click a parcel to see its details in a pop-up or side panel.
  4. Check the toolbar for a layer list or basemap switcher if you want aerials or other layers.

Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.

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.
