the courthouse into regular offices. It is likely but not proven that Orff also designed the separate sheriff's house and jail that were constructed at this time. Small, one-story additions were made to the front corners of the building between 1910 and 1915. The courthouse complex was modified again in the 1930s, when the county received federal New Deal funds to create jobs during the Great Depression. A crew under the Works Progress Administration (WPA) enlarged the courthouse basement and built an elaborate stone entry with street-level doors and stairs up to the original hilltop entrance. They also replaced the retaining wall at the foot of the hill, added a vestibule to the courthouse façade, replaced the windows, and refinished the interior walls. An annex was built into the courthouse hill in 1965 and another in 1980. Disuse and restoration In 1994 the historic courthouse was deemed unsuitable, partly due to noncompliance with the Americans with Disabilities Act of 1990. A new court facility opened in 1996 and most of the county offices had moved off-campus by 2004. Although a grant from the Minnesota Historical Society allowed for replacement of the roof and some windows, the old courthouse was completely vacated in 2006. With the aging building used merely for storage, the Todd County board of commissioners decided in 2009 that the courthouse had to be rehabilitated or demolished. The following year they put the matter to a county-wide vote, prompting the Preservation Alliance of Minnesota to place the courthouse on its "10 Most Endangered Historic Places" list for 2010. Although a study determined that the courthouse was structurally sound, the cost of rehabilitating it would be comparable to knocking it down and constructing a whole new building. Advocates of preservation campaigned by writing letters to the editor to the county's various newspapers and by soliciting letters of support from township supervisors and owners of local Century Farms. The resolution passed in the November 2010 election by fewer than 100 votes. Rehabilitation work began in late summer of 2011. An entrance ramp, elevator, and modernized restrooms addressed the accessibility issues. The arched windows were restored and the masonry was cleaned and repointed. The interior was reconfigured but original features such as the terrazzo floors and a pair of vault doors were preserved. New improvements included modern electrical equipment and a geothermal heat pump. The historic Todd County Courthouse—one of only
