Colorado GIS Maps by County: The Parcel Viewer Each Uses

Which parcel map software each Colorado county uses (58 of 64 verified), how to search the common viewers, and a link to every official map.

Looking for Colorado county GIS maps? Colorado has 64 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 details are.

If you look up land in more than one Colorado county, you will notice the parcel maps don't match. That is because each office chooses its own software. Below, all 64 Colorado entries in our directory are listed with the viewer each one uses, plus tips for the most common types.

The most populous counties

The busiest offices are worth knowing first, since most searches land there.

How to search the most common viewers in Colorado

county web map (18 entries, e.g. Adams County, Arapahoe County, Boulder County)

1. Open the official map link from the county's page; it opens in a new tab.
2. Accept any disclaimer, then look for a search box that takes street addresses, owners or parcel IDs.
3. Zoom in and click a parcel to see its details.
4. Use the map's layer controls to add aerials or other layers if they're offered.

Colorado Public Parcel Map (12 entries, e.g. Custer County, Logan County, Montezuma County)

1. From the county's Platbookmapper page, open the Colorado Public Parcel Map link. It opens in a new tab.
2. Search for an address or parcel number if the viewer has a search box, or pan and zoom to the property.
3. Click a parcel to read the attributes the statewide layer carries. Field names vary from county to county.
4. Statewide layers are compiled copies, so confirm ownership, tax and deed details with the county's own assessor or recorder.

ArcGIS Experience Builder (10 entries, e.g. Cheyenne County, Costilla County, Douglas County)

1. 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.
2. Search by address or parcel ID, or pan to the area.
3. Select a parcel to view the information the publisher makes available.
4. Explore the app's panels for layers, legends or printing.

Every Colorado entry and its viewer

Before you rely on what you find

Treat these maps as a starting point. Parcel outlines are tax-map drawings and can be off from the true line; the recorded deed and a licensed survey are what count. 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.
