Idaho GIS Maps by County: The Parcel Viewer Each Uses
Which parcel map software each Idaho county uses (44 of 44 verified), how to search the common viewers, and a link to every official map.
Looking for Idaho county GIS websites? Idaho has 44 counties, and their official parcel maps do not all run on the same software. Knowing which viewer a county uses tells you what the search box expects and where the parcel report is.
Idaho does not run one statewide parcel map that every county uses. Each local government picks its own viewer, so the screen you see in one county can look nothing like the one next door. This guide sorts all 44 Idaho entries in the Platbookmapper directory with the software behind each official map.
Idaho at a glance
- Entries in the directory: 44
- With a verified public parcel viewer: 44
- ArcGIS Experience Builder: 25
- ArcGIS Map Viewer: 13
- ArcGIS Web AppBuilder: 3
- county web map: 3
13 of these entries point to a statewide viewer rather than a county-run site (Idaho statewide Parcels layer in ArcGIS Map Viewer). A statewide map is handy for crossing county lines, but the local office is still where deeds and tax records are kept.

How to search the most common viewers in Idaho
ArcGIS Experience Builder (25 entries, e.g. Adams County, Bannock County, Benewah County)
- Open the official map link from the county's page; an ArcGIS Experience Builder app opens in a new tab. Accept any splash or disclaimer screen.
- Search by address or parcel ID, or pan to the area.
- Select a parcel to view the information the publisher makes available.
- Explore the app's panels for layers, legends or printing.
ArcGIS Map Viewer (13 entries, e.g. Bear Lake County, Bingham County, Blaine County)
- Open the official map link from the county's page; 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.
ArcGIS Web AppBuilder (3 entries, e.g. Ada County, Canyon County, Idaho County)
- Click the official map link on the county's page and wait for the Web AppBuilder viewer to load. Some counties show a terms screen first.
- Search by street address, owner or parcel ID if the search box offers those options.
- Click a lot on the map to read its attributes.
- Turn on aerial imagery from the basemap tool and use the layer list to add things like zoning or flood zones when they're published.

Before you rely on what you find
Online parcel lines are drawn for tax mapping, not surveys, so they can sit a few feet off the real boundary. For anything legal, such as a fence, a sale or a dispute, use the recorded deed and a licensed surveyor. To check flood zones, soils or wetlands for a spot you found, open it on the Platbookmapper Land Map, which pulls FEMA, USDA and U.S. Fish & Wildlife layers.
