Masking Requirements and Guidance

Here’s a quick breakdown of the new rules for outdoor and indoor settings:

  • Capacity limitations: No restrictions

  • Physical distancing: No restrictions for attendees, customers and guests. Workers on the job must maintain physical distancing and schools should keep student desks at least 3 feet apart.

  • Masking: Fully vaccinated people do not need to wear masks in most settings. Unvaccinated people must still wear masks in indoor public settings and businesses. Everyone must still wear masks in the workplace, on public transit, medical facilities, K-12 schools and correctional facilities and shelters.


Fully Vaccinated People

  • Masks are not required in most settings, except where required for All People (exceptions listed below)


Unvaccinated or Partially Vaccinated People

  • Masks are required for unvaccinated individuals in indoor public settings and businesses (examples: retail, restaurants, theaters, family entertainment centers, meetings, state and local government offices serving the public)


All People

Both fully vaccinated and unvaccinated people must wear masks in these settings:

  • Public transit (examples: airplanes, ships, ferries, trains, subways, buses, taxis, and ride-shares)

  • Transportation hubs (examples: airport, bus terminal, marina, train station, seaport or other port, subway station, or any other area that provides transportation)

  • Workplace: Masks must continue to be worn on the job. Cal/OSHA will be reviewing its masking guidance for employers and workers on June 17. 

  • K-12 schools, childcare facilities and other youth settings (indoors)

  • Businesses that choose to require masks for all customers

  • Healthcare settings (including long-term care facilities)
