Hawkins, the county physician and health officer of Douglas County.

While Hawkins anticipated that Douglas County would need a modern hospital for its growing population, the county's population actually fell at the 1920 census, and the community struggled to keep its hospital open.

The Gardnerville Branch Jail is a historic jail located at 1440 Courthouse St. in Gardnerville, Nevada. The jail was built in 1910 and served as Douglas County's only jail from 1910 to 1915. Prior to 1910, the only county jail was in Genoa, the county seat; however, since Gardnerville was several miles from Genoa, it resorted to housing prisoners in the local judge's granary. As the granary was considered unfit for holding prisoners, the community petitioned the county to construct a new jail. However, local leaders in Minden, who wanted to move the county seat to their town, protested the move, as they suspected that Gardnerville was attempting to claim the county seat itself. Nonetheless, the county approved the construction of the new jail. The jail housed its first prisoners before construction even finished, as the Genoa jail burned down; one prisoner was briefly chained to a post until the new jail could accommodate him. Once completed, the jail served the county until 1915, when Minden became the county seat and opened its own county jail.Once it no longer served as the county jail, the Gardnerville jail took on another, racist purpose. Gardnerville was a sundown town, and it rang a bell every night to order American Indians out of town. In addition, the unemployed were considered vagrants and were not allowed on the town's streets after dark. The jail housed violators of both of these policies until it closed in the 1950s.The jail was added to the National Register of Historic Places on May 16, 2003.

The Minden Flour Milling Company is a historic flour mill located at 1609 U.S. Highway 395 in Minden, Nevada. Built in 1906, the mill was the largest of five flour mills built in the Carson Valley and is the only one still in existence. The building has a transitional design in two respects, as it reflects the change from early European-influenced mills to 20th-century American mills as well as the move from smaller rural mills to large mills built along railroads. The mill features a masonry bearing-wall style of construction, a concrete foundation considered novel at the time, and well-crafted masonry and woodwork. The operators of the mill had a significant influence on Minden commerce, as they were instrumental in both the extension of the Virginia and Truckee Railroad to the town and the expansion of electric power to the area. By the 1920s, the mill had become "one of the biggest milling concerns in the state"; it could process 100 barrels of flour a day and also produced chicken and cattle feed. The mill operated until the 1960s.The mill was added to the National Register of Historic Places on November 14, 1978.
