The Department of the County Assessor offers a variety of Geographic Information System (GIS) applications for public access. There are several GIS applications including a Map Gallery of PDF maps that you can print or save. While we strive to provide the taxpayers of Jefferson County pertinent information, we are always open to suggestions. If there is an application or information you would like to see on our website reach out to us. We will do our best to locate the data for you.
