The San Dimas Hotel, also known as Walker House, the Carruthers Home, and the San Dimas Mansion, is a historic structure in San Dimas, California, built by the San Jose Ranch Company in 1887. Originally built as a hotel, the 15,000-square-foot (1,400 m2) structure had 33 rooms and 14 fireplaces. The hotel was built in anticipation of a land boom that never happened, and it never had a paying guest. In 1889, the property was sold to James W. and Sue Walker for $25,000.
