UPDATE: On August 2, Marin County joined other Bay Area Counties in requiring the use of masks indoors by all people -- vaccinated or unvaccinated -- out of an abundance of caution due to a rising number of COVID-19 cases.

Masks are not required outdoors, but are strongly recommended in crowded environments.


Guidance for Individuals 

Beginning August 2, everyone must wear a face covering over the nose and mouth in all indoor settings, such as offices, retail stores, restaurants and bars, theaters, family entertainment centers, conference centers, and State and local government offices serving the public.

Everyone is strongly encouraged to also wear masks indoors at private gatherings where vaccination status cannot be confirmed.

Guidance for Businesses, Venue Operators or Hosts**

Individuals, businesses, venue operators, hosts, and others responsible for the operation of indoor public settings must:

  • Require all employees, contractors, visitors, and patrons to wear face coverings in all indoor settings, regardless of their vaccination status; and
  • Post clearly visible and easy-to-read signage at all entry points for indoor settings to communicate the masking requirements to all patrons.

In addition, those responsible for indoor public settings are strongly encouraged to provide face coverings at no cost to individuals required to wear them.

**No person can be prevented from wearing a mask as a condition of participation in an activity or entry into a business.

Masks in the Workplace

Cal/OSHA has aligned workplace mask requirements with general mask guidance from the CDPH. For more information, see Cal/OSHA’s COVID-19 Prevention Emergency Temporary Standards.

Please see current masking guidance for the State of California for masking exceptions.


Wear your mask correctly

  • Put it over your nose and mouth and secure it under your chin
  • Try to fit it snugly against the sides of your face
  • Make sure you can breathe easily
  • A face covering can be made of cloth, fabric, or other breathable material, but it should not have holes
