California Commits $190 Million to Expand Bay Area Addiction Treatment Capacity

More than $190 million in state funding will flow to eight new mental health and drug treatment facilities across the Bay Area, part of a $6.4 billion bond voters narrowly approved in 2024 to address California's acute shortage of treatment beds.

Governor Gavin Newsom announced the latest round of Proposition 1 grants Wednesday, totaling nearly $1.2 billion statewide. The bond was designed to build behavioral health treatment infrastructure for people struggling with mental illness and addiction—conditions that, when severe and under-treated, can send individuals into emergency rooms, jails, or homelessness.

Among the Bay Area projects approved by the California Department of Health Care Services are $7 million for an outpatient mental health center in Berkeley with 80 treatment slots, approximately $14 million for a 44-bed residential drug treatment facility on Treasure Island in San Francisco, and $25 million for an integrated sobering and treatment center in San Mateo with 69 beds.

"With this final round of awards, we're not slowing down," Newsom said in a statement. "We're building a behavioral health system that actually meets the scale of the crisis—one that delivers treatment, support, and real stability for people who've been left behind for far too long."

Filling Critical Gaps in Peninsula Services

The Horizon Recovery Center in San Mateo represents a direct response to a service gap that opened in October 2024 when the county lost its only sobering center. That facility, run by nonprofit Star Vista, had provided a safe medical environment where people arrested for driving under the influence could sober up rather than being booked into jail.

The closure followed a state agency decision to change how it reimburses providers of treatment services, forcing law enforcement to bring more intoxicated individuals to the county's main jail in Redwood City.

Horizon Treatment Services, which will operate the new $25.5 million facility, plans a multi-stage recovery model. The center will include 16 sobering beds for short-term stays lasting less than 24 hours, 17 beds for intensive detoxification programs where patients may remain up to a week, and 36 beds for longer-term residential treatment spanning several months.

"That's really where a lot of the magic happens," CEO Jaime Campos said of residential treatment. "That's where you're there to change a life. Reestablishing family relationships, or getting custody of your kids back."

The facility is expected to open in San Mateo in 2028 or 2029. San Mateo County's Board of Supervisors allocated $2 million from opioid settlement funds to support the project, and San Mateo Medical Center has backed the effort because officials anticipate it will reduce the number of people in addiction crises arriving in its emergency department.

However, the project has generated neighborhood concerns. Supervisor David Canepa, who does not represent the city of San Mateo, said his office received a surge of complaints from residents worried about the impact of the facility's proposed location in a dense neighborhood near Highway 82 and Tilton Avenue.

"It would stick out like a sore thumb," Canepa said.

Campos said Horizon staff held a community listening session in February and are incorporating feedback into the design. The nonprofit is also prepared to present the project to the San Mateo City Council.

San Francisco Concentrates Recovery Programs on Treasure Island

San Francisco continues expanding addiction treatment capacity on Treasure Island, a man-made island in the middle of the Bay where city officials have begun concentrating recovery programs. The latest Proposition 1 grants include $14.2 million for the San Francisco Department of Public Health to build a 44-bed residential drug treatment facility on the island.

Details of the project were not immediately available, and a spokesperson for the department did not comment on the new funding, referring questions to previous reporting about earlier treatment programs planned for the island.

Statewide Expansion and Implementation Challenges

When completed, the projects from this latest batch of grants and earlier rounds of Proposition 1 funding are expected to add nearly 7,000 treatment beds and more than 27,500 other treatment slots statewide, according to the governor's office.

The newly funded Bay Area facilities are slated to open within a few years, according to the health care agency, although timelines for large state-funded construction projects often shift. The funding announced Wednesday represents the second major round of Proposition 1 grants.

In May 2025, Newsom unveiled $3.3 billion for behavioral health projects across California, including in the Bay Area. Some were initially expected to open by the end of that year, but construction is still underway.

"Adjustments in timelines of large-scale projects are not unusual," Newsom spokesperson Tara Gallegos said in an email, citing permitting, site conditions, and construction challenges.

Newsom championed Proposition 1 as a cornerstone of the state's effort to address homelessness and addiction. The money has rolled out alongside other initiatives, including CARE Court, a collaborative justice process for unhoused people with serious mental illness, and increased pressure on cities to clear homeless encampments.

Additional Proposition 1 funding in this round will support behavioral health treatment projects in Vallejo, Napa, and Fairfield. Solano County received $37 million for its planned Behavioral Health Recovery Campus in Fairfield, which will include residential treatment, a crisis stabilization unit, and a sobering center, slated to open in December 2028.

San Mateo County, home to approximately 750,000 residents, represents one of the most dramatic examples of how state policy changes can disrupt local treatment infrastructure. The loss of its sobering center in 2024 created immediate pressure on law enforcement and emergency services, highlighting the fragility of the safety net for people experiencing addiction crises.

The Horizon Recovery Center's multi-stage design reflects a growing understanding that effective addiction treatment requires a continuum of care—from immediate medical stabilization to intensive detoxification to long-term residential programs where individuals can rebuild their lives. The integration of these services in a single facility represents a departure from the fragmented approach that has characterized much of California's behavioral health system.

As California works to deploy billions in Proposition 1 funding over the coming years, the success of facilities like Horizon Recovery Center may determine whether the state can finally match the scale of its treatment infrastructure to the magnitude of its addiction and mental health crisis.
