McDonald Mansion
Also known as: Mableton
Why it's listed
Mableton, also called the McDonald Mansion, is a large Victorian house at 1015 McDonald Avenue in Santa Rosa. A San Francisco financier built it in 1876 as the finest structure in the 160-acre McDonald Addition. The frame house rises well above its grounds, with a columned veranda on three sides, a paneled baronial entry hall with a skylight, eleven bedrooms, and a carriage house and gazebo nearby. Its design blends stick style, Gothic, Greek Revival and Galveston elements, and its large formal rooms were unusual for the North Coast. The nomination calls it probably among the largest houses of its style in California. It is also linked to Colonel Mark L. McDonald, who developed Santa Rosa's water works and horsedrawn streetcar system. The house later served as a setting for civic events and a Disney film. At the time of nomination it looked run down because of overgrown grounds, but inspections found it sound and restoration feasible.
Significance in brief: The nomination argues the house is architecturally unusual, combining stick style, Gothic, Greek Revival and Galveston-style features with generous formal rooms rare on the North Coast. It is also tied to Colonel Mark L. McDonald, a financier who developed Santa Rosa's water works and streetcar system. The property has local recognition and was a filming location for Disney's "Pollyana".

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.
