In 2009, the Stanford outpatient clinics, which were running out of expansion room, were relocated to the Stanford Medicine Outpatient Center, a large new site in Redwood City, California formerly occupied by the corporate headquarters of Excite@Home. The buildings were extensively remodeled for medical use to provide facilities the clinics' old homes lacked. For example, the Sleep Medicine Center's new sleep lab has thorough soundproofing and can accommodate a few morbidly obese patients. In 2018, these outpatient facilities were expanded to receive the main campuses outgoing Digestive Health Center and endoscopy suite, to make room for the new expansions/renovations at the main Stanford Hospital, in addition to nearly doubling the existing imaging facilities and adding an external parking structure at the Stanford Outpatient Center.
