San Francisco will provide 50 locked mental health treatment beds at UCSF Health Hyde Hospital on Nob Hill and a 44-bed residential addiction center on Treasure Island.

The facilities are part of almost $100 million in expanded access to recovery and treatment services announced by Mayor Daniel Lurie on Thursday.

The 50 subacute locked beds will rehabilitate space at the former Saint Francis Memorial Hospital for people under mental health conservatorship. Six acute psychiatric beds will also be added to an existing 24-bed unit there.

The city will put 44 residential addiction treatment beds at a new city-owned behavioral health facility on Treasure Island, the mayor said. 

San Francisco will also transform an unused city building at 1660 Mission St. into a hub for coordinated behavioral health care and a sobering center, according to the mayor’s office. 

“San Franciscans struggling with addiction and serious mental illness should have a path to treatment and recovery,” Lurie said in a press release. “With more residential addiction treatment, locked beds, and recovery services, we can connect more people to care, keep them on the path to stability, and get people off the streets.”

Construction of the 44-bed residential substance use facility on Treasure Island will begin in winter 2026.  

A 64,000-square-foot, six-story building at Tradewinds Avenue and Mackey Lane will also be home to hundreds of recovery housing beds, including 172 existing Treasure Island beds, which will be relocated from former U.S. Navy housing.  

The San Francisco Department of Public Health and UCSF Health applied for capital funding for these projects under Proposition 1, a $4 billion program approved by California voters in March 2024.
