Health Orders | Coronavirus

Legal authority for County Health Officer orders addressing the COVID-19 pandemic is in the California Health and Safety Code, which grants broad powers to the Health Officer to protect public health during local emergencies and prevent the spread of contagious diseases. The statutes include Health and Safety Code sections 101040 and 120175. As actions taken under this statutory authority, Health Officer orders are measures taken to preserve the public health, which is an exercise of the police power contained in the California Constitution. 

Social Distancing Order

Amended: 7/11/2020

Contra Costa County is experiencing a significant increase in community transmission and illness from COVID-19. The rate of occurrence of new cases per day and hospitalization rates have been steadily rising since early June.  The percentage of test results positive for the virus has been steadily rising since June 20, 2020.  For those reasons, this amended health order imposes additional restrictions on certain businesses and activities that were previously cleared for operation because they present a high risk for disease transmission due to the prolonged contact between persons who come together in these businesses and engage in these activities. 

Based on our current understanding of the transmission of the COVID-19 virus, local case investigations, and knowledge gained from case investigations and outbreaks across the region and the state, there is a heightened concern about settings where people from multiple households gather.  Gatherings where people are together for a prolonged period of time, especially indoors, and settings where people remove their masks to eat and drink, appear to pose the highest risk for transmission at this time.


The following summarizes these restrictions:


  • Restaurants and other food facilities:  Specific face covering requirements are imposed at establishments that are open for outdoor dining only.  Indoor dining remains prohibited. (See face coverings health order and Appendix C-1 below)

  • Providers of religious services and cultural ceremonies:  Indoor religious services and cultural ceremonies are prohibited.  Outdoor religious services and cultural ceremonies may be held in accordance with applicable State guidance.

  • Protests:  Indoor protests are prohibited.  Outdoor protests may take place in accordance with applicable State guidance.

  • Social Bubble gatherings: Persons over age 2 are required to wear face coverings, except when eating or drinking, and all gatherings must take place outdoors.
