Built in 1918 as a gift to Corona Williams and Robert Anderson. The house had colonial mansion decoration, and the inside of the house resembled east coast architecture. In 1983 the house was sold to Peggy W. Woodring, Robert Bell and, JoAnne Fabian. Unfortunately the house was empty and ran down that they had to remodel everything. After remodeling the house had an increase in the number of bedrooms to 11 and bathrooms to 5 and a half. In 2006 the house was placed on the market and the executive committee of the Board of Trustees of Dominican University of California became interested in the house.
The interest for Magnolia house was due to its close proximity to campus, Caleruega, and the availability of more office space. In February 15, 2007 Dominican purchased Magnolia house for $5.4 million. Magnolia house is now home to admissions and Human Resources.
