Sun House
Also known as: Hudson-Carpenter Estate
Why it's listed
Sun House is a redwood craftsman-bungalow at 431 South Main Street in Ukiah, built in 1911-1912 to a design by architect and artist George L. Wilcox. The square, board-and-batten dwelling has seven rooms, a gable roof with wide eaves, two brick fireplaces, redwood paneling and beams, and an artist's studio. It stands on 0.4 acre among redwoods, oaks and gardens. Grace Hudson, a nationally recognized painter, and her husband, Dr. John Hudson, an ethnologist who recorded the Pomo language and collected baskets and other artifacts, lived and worked here from 1911 to 1937. The nomination presents the house as the most important example of this early twentieth-century style in Mendocino County, notable for its use of local redwood and Indian-inspired designs worked into the wood. Later owners kept it largely original, and it was sold to the City of Ukiah to serve as an art and historical museum. Only minor alterations, such as a 1938 roof change and a 1940s bedroom enlargement, are noted.
Significance in brief: The nomination argues the house is the most important example of craftsman/bungalow architecture of the early 1900s in Mendocino County, built of massive local redwood. It is also tied to owner-builders Grace Hudson, a nationally recognized painter, and Dr. John Hudson, an ethnologist who recorded the Pomo language and collected artifacts. The house retains the integrity it had during the Hudsons' time.

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.
