The purpose of the Brown County Property Listing Department is to process the documents that affect land boundary location, title interest and extents, and property taxation status so land interest can be identified, listed, mapped, assessed, and taxed; to preserve and maintain the Public Land Survey System (PLSS) and the records thereof, and provide technical and/or professional assistance to the public concerning issues related to land ownership or location.

The Property Listing Department's function is to carry out statutory duties to create and maintain a current property listing file and mapping system which accurately displays the ownership, mailing address, taxing status, geographic location, enclosed area, and a map of every tax parcel of land within the County. The department also carries out the statutory duties to maintain the Public Land Survey System and file, index and maintain the survey and monument records within the County for retrieval purposes.
