History

The area was first occupied by Indigenous peoples who discovered and used the hot springs that the area is named after. The Mexican government deeded 50,000 acres to Lazaro Piña as Rancho Agua Caliente, a land grant 10 miles (16 km) long on the east side of Sonoma Creek, in 1840. In 1849 Thaddeus M. Leavenworth acquired 320 acres of the Rancho in what became present-day Agua Caliente, Fetters Hot Springs, Boyes Hot Springs, and part of Maxwell Farm. In 1889, property was being sold in the area as being near the "celebrated old Indian Medicine Spring."

George and Emma Fetters opened the Fetters Hot Springs resort in 1908. Flamboyant restaurateur Juanita Musson opened her second Sonoma Valley restaurant in the old Fetters hotel around 1970, but it burned to the ground five years later. The land stood vacant for almost forty years until the Fetters Apartments, built as affordable housing for sixty families, opened in 2017.
