Contra Costa County Face Coverings

“Members of the public must mask when they:

work at an essential business
are inside an essential business, such as a grocery store
visit a healthcare provider or facility
wait in line for or ride public transportation

Businesses must take reasonable measures, such as posting signs, to remind visitors about masking, and not serve customers who do not observe the order. Workers do not need to mask if they are alone in a personal office but must put them on when others enter.”
