Mask mandates in Bay Area counties
Alameda
On Thursday, June 2, Alameda County health officials announced they were reinstating a mask mandate for most indoor public settings beginning on June 3, regardless of vaccination status.
The new health order does not apply to the city of Berkeley, which has its own public health department.
This means both unvaccinated and vaccinated people are once again required to wear masks in most indoor public spaces, including businesses, restaurants and bars, government offices, public transportation, bus and train stations, hospitals and correctional centers.
An existing indoor mask mandate remans in effect for health care settings, congregate settings like correctional facilities and homeless shelters, and long-term care facilities, and in K-12 schools and child care settings.
An earlier indoor mask mandate at all schools that are part of Berkeley Unified School District began May 23. District officials announced this change on May 20 and added that BUSD " is experiencing an increase in the number of classroom clusters which indicate likely transmission in school."
The mask mandate for BUSD schools will be in place until the end of the 2021-2022 school year.
San Francisco
On June 2, following Alameda County's announcement of a renewed indoor mask mandate, San Francisco officials told KQED that they don't have plans to reinstate a similar mask mandate at this time.
As of Feb. 16, people who are up to date with their eligible COVID-19 vaccinations — this includes booster shots if you currently qualify — can take their masks off in indoor public spaces in San Francisco. Officials confirmed that San Francisco aligned with the state's guidance to extend this to unvaccinated people as of March 1.
