Heritage House
Also known as: Bettner House
Why it's listed
Built in 1891 at 8193 Magnolia Avenue in Riverside, this three-story Queen Anne mansion has a white frame exterior, a steep shingle roof and an octagonal tower at one front corner. It still sits on its original site, facing the double avenue of magnolia, pepper, palm and eucalyptus trees. The house was built by the widow of James Bettner, a leader in the early citrus industry and a founder of the California Fruit Growers Exchange, later Sunkist. Architect John H. Walls of the Los Angeles firm Morgan and Walls designed it. Original features survive, including extensive interior paneling, six tile-bordered fireplaces, a wood-burning kitchen stove, shutters and an adobe cooler, along with the carriage house. The nomination presents the property as a rare survivor of the affluent homes along Magnolia Avenue and as a link to Southern California's citrus boom. A local non-profit bought it in 1969 and began restoring it as a museum and educational center.
Significance in brief: The nomination argues the house is significant in local history and culture through its link to the early citrus industry in Southern California. It was built by the widow of James Bettner, a leader in the citrus industry and a founder of the California Fruit Growers Exchange, later Sunkist. It is also a fine example of the 1890s homes that lined Magnolia Avenue, designed by architect John H. Walls of Morgan and Walls.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
