About the Angel Island Immigration Station Hospital

The former Immigration Station Hospital was rehabilitated for adaptive re-use as a museum for the immigrant story as well as a small conference center operated by California State Parks. The interpretive exhibits connect the past to current immigrant stories.

The 10,000 sf Hospital, constructed c.1908, represents a major part of the immigrant experience for those entering the United States on the West Coast. Programming following a workshop with all stakeholders guided the future rehabilitation design, and use of the building. The Program Document and updated HSR, guided the team of preservation architect, civil, structural, mechanical, electrical, and plumbing engineers, and cost estimator to develop an overall rehabilitation design. The mix of funding sources and timing of funding required phasing of construction. First was initial stabilization and remediation of the building; Second was infrastructure scope of electrical service and distribution rough-in, elevator and egress path bridges; Third was functional improvements scope of the seismic upgrade, mechanical, electrical, and plumbing systems, along with tenant improvements of most but not all rooms; Fourth was tenant improvements of the remaining unfinished rooms followed by the installation of the museum and interpretive elements.
