A $500M donation from the Helen Diller Foundation will help UCSF rebuild its Parnassus Heights Hospital in the Inner Sunset District of San Francisco. The educational and health institution will begin planning to rebuild the hospital by 2030 following state seismic requirements, the San Francisco Business Times reports. The hospital construction is expected to cost at least $1.5B.

UCSF is not the only healthcare institution undergoing a hospital rebuild. Due to current seismic standards, hospitals across the state have had to draw up plans for massive renovations and many have used this opportunity to add beds and new buildings.

UCSF Benioff Children’s Hospital in Oakland is expanding its hospital, and Stanford completed a major rebuild of its main building at Lucille Packard Children’s Hospital in December. The 521K SF building more than doubled the size of its pediatric and obstetric hospital campus and added 149 patient beds. Stanford Hospital is nearing completion of its new 824K SF seven-story hospital that will offer 368 beds. The hospital is expected to open sometime this year.

Marin General Hospital in Greenbrae is undergoing a $535M replacement project with Phase 1 to be completed in mid-2020. This phase will include a new modernized four-story 260K SF hospital replacement and new towers with 114 private rooms, an expanded emergency department and six new operating/procedural suites.

The seismic requirements are resulting in hospital closures in some cases. In Berkeley, Sutter Health plans to end hospital and emergency room services at Alta Bates since it lacks the funding to renovate the hospital to current seismic standards.
