Historic Building Survey plaque: "1 William Heath Davis House, 1850. The Davis House is the oldest surviving structure from San Diego's New Town. It is an example of a prefabricated, "salt-box" style home. Built on the East Coast, shipped around Cape Horn, and assembled in San Diego, the Davis House originally stood on Sate and Market, but was moved to 11th Avenue, then finally to its present site in 1984. Along with being a residence, it also has served as a county hospital."
