The Arizona Rancho is a rambling multistory building located on the southern edge of Holbrook's downtown business district. For most of its existence it has been a lodging facility-first a boarding house, then a hotel and motel. Originally constructed as a private residence between 1881 and 1883, it began as a small building with a rectangular floorplan. Over the succeeding years, a series of additions was made as the building was operated first as a boarding house and then as a hotel; these additions produced an L-shaped building. In the 1940s, a walled compound was constructed that included not only the L-shaped building but also an attached block of motel rooms and several other additions. - NRHP Registration Form, 10 October 1997
