The University of Wisconsin-Platteville recognizes its commitment to the requests of facility use by the University Community and residents of the state to the extent resources permit. The document sets forth the policies governing the use of all campus facilities (buildings and surrounding and connecting grounds). Non-University groups may use facilities only upon the invitation of or under the sponsorship of a University department or organization as specified in UWS 21.
The Use of University Facilities Policy located here: https://uwplatt.teamdynamix.com/TDClient/111/Portal/KB/ArticleDet?ID=12914, outlines process and delegated authority.
