It is also argued to be an excellent example of Queen Anne architecture in the county, and the mule barn an excellent turn-of-the-century livestock barn. It is the only extant ranch house from Camarillo's early development period.","narrative":"Built in 1892, the Camarillo Ranch House is a two-story Queen Anne residence in Camarillo, California, with a three-story octagonal tower, a wraparound veranda and fish-scale shingle detailing. It was the home of rancher Adolfo Camarillo, who became one of the largest landowners and most influential citizens in Ventura County. The surrounding ranch once covered 10,000 acres, but most of its outbuildings were demolished in 1999 for new development. The 4.49-acre parcel retains the house, a ca. 1905 wood-frame mule barn moved in one piece, and a 1967 stable. The house was restored in 1999-2000 and now operates as a museum and event site owned by the city. Its significance rests on Camarillo's role in county agriculture between 1892 and 1952, on the house as a fine local example of Queen Anne architecture, and on the mule barn as a typical turn-of-the-century livestock barn. It is the only surviving ranch house from Camarillo's early development.","period_of_significance":"1892-1952","architect_builder":"Anlauf, Herman; Ward, Franklin","architectural_style":"Late Victorian: Queen Anne; Other: Wood-frame Mule Barn","criteria":["B","C"],"status_note":"Owned by the City of Camarillo and operated as a house museum and event venue; restored 1999-2000 and described as in excellent condition.
