Active Health Orders


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. 

Health Orders for the General Public

Social Distancing Order

Date of Order: 6/16/2020

This Order supersedes the June 5, 2020, Order of the Health Officer directing all individuals to socially distance (“Prior Order”). This Order continues to restrict most activity, travel, and governmental and business functions to essential needs and to the Outdoor Activities and Outdoor Businesses that the prior Order allowed to resume.  But in light of progress achieved in slowing the spread of COVID-19 in the County of Contra Costa (the “County”), and in accordance with a variance obtained by the County from the State of California on June 9, 2020, which allows the County to move more quickly, or in a different order, through Stage 2 of the State of California’s COVID-19 roadmap to recovery, this Order eases restrictions to allow additional businesses to resume or begin operating, subject to conditions set forth in applicable industry guidelines issued by the State. This Order also modifies restrictions that applied to outdoor recreation activities, childcare facilities, outdoor dining, campgrounds and outdoor pools.
