I want to thank you for visiting the County Assessor site. The constitutional duty of the assessor is to evaluate all property in the county for property tax purposes. We do this fairly and equitably according to Wyoming State Law.
Below is a link to the new online ownership map. This map is structured differently than our previous version. On the access page there is a tutorial and "Help" in the “Tools” map tab also gives a brief guide how to navigate the site. For first time users we recommend reading the tutorial before starting. Please contact our office at 307-721-2511 and we will help answer any questions you may have.
The Property Listings page is no longer available. All ownership and property information is available on the County Mapserver.
The data available will be current information except property value. By State law assessors value once a tax year January 1st so values will remain the same all year. Other information such as ownership change, updated mailing address, new subdivisions and new structures will be published daily as information becomes available to our office. Photographs and building sketches are available on the details page.
