The Sarah Eliza Harris House, located at 375 E. 200 North in Beaver, Utah, is a historic house built up around an original adobe cabin from c.1865. The main part was built c.1874; an east addition with an unusual bay window was built c.1895 (probably built by mason Louis W. Harris who owned it during 1884-1897, and probably incorporating brick underneath stucco). It is significant because of its age, its use of adobe in its 16-inch (0.41 m) thick walls, and its generally unaltered condition since 1895. It was listed on the National Register of Historic Places in 1983.
