Constructed in 1901, the Stevens-Haustgen House bungalow features wide porches and low rooflines. This style was typical of homes built in California at the turn of the century. It was built by Constance Stevens, who lived in the nearby Stevens House, to be used as a rental property. In 1911 a man named Edward Haustgen purchased the house and rented it out to his sisters Anna and Marguerite from 1937-1952. Today, the house is the location of the Heritage Gallery which features changing exhibits. Visitors can tour the house as part of the Rosson House Museum tour.
