About the official source

This map is published by or for Ketchikan Gateway Borough 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.

How to use the Ketchikan Gateway Borough viewer

  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.

Before you rely on the lines

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.
