Gladstone Houses
Why it's listed
Two Craftsman-style houses sit on a steep, wooded site at the end of Cline Gulch, northeast of French Gulch in Shasta County. Both were built for I. O. Jillson, owner of the Gladstone Mine, and are attributed to designer Gustav Stickley. The Upper House, from about 1909, is a story-and-a-half building with a steep gable roof. The larger Lower Mansion, built about 1912-1914, has an L-shaped plan and a triple-intersecting hipped roof. Both have redwood shingle walls, extensive interior woodwork, and rock or hillside foundations engineered with help from the mine's staff. Plans for the Upper House appeared in The Craftsman in 1909, and the Lower Mansion was featured in 1914. The houses are listed for their link to Jillson, whose mining operations contributed to the local economy, and for their Craftsman design. Few such buildings survive in the area. The Lower Mansion is vacant and in poor condition, while the Upper House is in fair condition and little altered.
Significance in brief: The houses are tied to I. O. Jillson, a prominent Northern California gold mine owner, who built them while running the Gladstone Mine between 1901 and 1916. They are also attributed to Gustav Stickley, the leading figure of the American Arts and Crafts movement, and both appeared in The Craftsman magazine. Few Craftsman buildings exist in the Shasta County area, and none are known to be by a designer of Stickley's renown.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved. See what listing means in practice.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
