Latest Information about San Mateo County

As of March 17, the County of San Mateo was the FIRST Bay Area County to move into the Moderate (Orange) Tier under California's Blueprint for a Safer Economy. Under the Orange Tier, there is a significant increase in indoor capacities for restaurants, museums/zoos/aquariums, gyms, wineries/breweries, movie theaters, among other things.

The State of California announced that on June 15, California will fully reopen as long as the vaccine supply is sufficient for Californians (16 years and older) who wish to be inoculated and if hospitalization rates are stable and low. Read Governor Newson’s announcement for more information.

In regards to domestic travel, the CDC recommends delaying travel until a person is fully vaccinated because travel increases your chance of getting and spreading COVID-19. If you are not fully vaccinated and must travel, follow CDC’s recommendations for unvaccinated people. Travelers are still required to wear a mask, keep their distance, and wash their hands frequently. This guidance applies to travel within the United States and U.S. territories.

From the California Department of Public Health's perspective, non-essential travelers from other states or countries, regardless of COVID-19 vaccination status, are strongly discouraged from entering California and should adhere to the quarantine and testing procedures.

Additionally, the Biden Administration has imposed an international travel ban affecting inbound traffic from these countries. U.S. citizens returning from travel abroad must show proof of negative COVID test and abide by applicable quarantine rules.


On Friday, April 2, the California Department of Public Health announced that it is in the process of issuing meeting and event guidelines that will allow gatherings effective April 15!

In San Mateo County's current Orange Tier, outdoor gatherings are limited to 100 people, and capacity increases to 300 if all guests are tested or show proof of full vaccination. In this tier, indoor activities are allowed if all guests are tested or show full proof of vaccination; capacity is limited to 150 people.

San Mateo County is soon expected to advance to the Yellow Tier, where outdoor gatherings will be limited to 200 people, and capacity increases to 400 if all guests are tested or show proof of full vaccination. In this tier, indoor activities are allowed if all guests are tested or show full proof of vaccination; capacity is limited to 200 people. 

The state is soon expected to announce guidance for a Green Tier that will allow large conventions. View the updated sector chart to see which activities and businesses are allowed in each tier.


As of April 16, 2021, many employers in the hospitality/tourism sector are required to hire back laid-off employees first (before hiring others), if the employees were let go for a reason related to the COVID-19 pandemic. Senate Bill 93 (SB 93) went into law on April 16th with immediate effect, and it impacts employers’ hiring process and decisions through December 31, 2024. This new law affects the following categories of employers: hotels, private clubs, event centers, airport hospitality operations, airport service providers, and building service providers. The experts at Hoge Fenton will conduct a webinar on this subject on April 28, 2021, at 12:00 PM. Read more about this new legislation.

Cleaning and Disinfection for Community Facilities

The Centers for Disease Control and Prevention has offered guidance providing recommendations on the cleaning and disinfection of rooms or areas occupied by those with suspected or with confirmed COVID-19. It is aimed at limiting the survival of SARS-CoV-2 in key environments. These recommendations will be updated if additional information becomes available.

These guidelines are focused on community, non-healthcare facilities such as schools, institutions of higher education, offices, daycare centers, businesses, and community centers that do, and do not, house persons overnight. These guidelines are not meant for cleaning staff in healthcare facilities or repatriation sites, households, or for others for whom specific guidance already exists.
