How much time does it take to nominate a property to the registers?
This depends on the type and location of the property, among other things. The nominator frequently must research and photograph the property and must, of course, complete the required forms and submit them to the Wisconsin Historical Society, where the nomination is reviewed by staff and scheduled for review and approval by the State Historic Preservation Review Board, which meets quarterly. State Register nominations are approved at the state level. National Register nominations are approved by the National Park Service in Washington, D.C. All of this can take about one and a half years.
