The Lake County GIS Department is primarily responsible for maintaining Lake County's electronic spatial databases and creating products that assist with decision-making, records management, data collection, and information visualization.
Additionally, this office is responsible for assigning new addresses within the County that are outside of incorporated city limits, aiding in the creation of new road names, and providing the base with which the Plat Room parcel records are maintained. This office uses the backdrop of geospatial expertise to provide solutions for a wide array of information needs.
The GIS Department standard pricing was set by Lake County Board of Commissioners Resolution 22-21. If you have any questions regarding pricing or services, please email the GIS Department, call the office at (406) 883-7212, or visit us in person in the Lake County Courthouse.
To apply for a new address, please fill out the Address Application. Once an application is received, it can take 2 to 3 weeks to assign an address, dependent on weather.
