Reopening San Mateo Businesses

San Mateo County has been issued a variance so that more activities and business are allowed. The Health Officer issued a new Health Order on June 17, 2020 emphasizing individual behavior and the practices businesses must follow as they resume operations. The new Health Order is effective immediately and aligns with the Governor’s Phase 2 Reopening Plan.

Businesses in San Mateo County will now follow the state’s schedule for reopening but must adhere to the local order’s COVID-19 safety measures and follow state guidance. Businesses and individuals must follow additional safety precautions such as wearing face coverings and abiding by behavioral restrictions explained in the Health Order. Just because restrictions have been relaxed, does not mean the health crisis is over. If rates of infection increase, the Health Officer may reinstate closures and restrictions.

Statewide COVID-19 Hotline:

833-422-4255 (833-4CA-4ALL)

The statewide call center will be open 7 days a week:

Mon – Fri: 8:00 am to 8:00 pm
Sat & Sun: 8:00 am to 5:00 pm

County Face Covering and Social Distancing Requirements

As the county aligns with the state’s Resilience Roadmap, face covering and social distancing requirements remain in place:

Face Covering Requirements

Businesses are required to have employees, contractors, owners, and volunteers wear a face covering in the workplace and when they are interacting with others. Face coverings are also required where food is prepared or packaged for sale or distribution. Please review the County’s Health Order for additional information. The County has developed Face Covering Signage that businesses can download, print and post.

The Health Order emphasizes the need for individuals to comply by with face covering requirements. In general, even when not required by this Order, individuals (except for children aged two years or less) are strongly encouraged to wear face coverings when in public.  

Social Distancing Requirements

The County requires businesses to fill out a Social Distancing Protocol form and post a copy of the Social Distancing Protocol at each public entrance of the facility.

Businesses Allowed to Reopen and Industry-specific Guidance 

The requirements for businesses are outlined in the Health Order and appendix. Businesses must adhere to industry-specific guidelines from the state, which may be found below or at and

Each business must create and implement a written, worksite-specific COVID-19 plan and post your completed health and safety plan so the public is aware that you have complied with State guidance. The State has created a checklist for some sectors, which can be used as a framework for the plan. If no checklist exists, a business must still create a plan. If you cannot find applicable guidance, your business might not be allowed to reopen yet. 

Reopening Requirements

As businesses reopen, everyone will need to create a safer, low-risk environment. Before reopening, all facilities must:

  1. Perform a detailed risk assessment and create a site-specific protection plan
  2. Train employees on how to limit the spread of COVID-19. This includes how to screen themselves for symptoms and when to stay home.
  3. Set up individual control measures and screenings
  4. Put disinfection protocols in place
  5. Establish physical distancing guidelines

It’s important that employees with COVID-19 know they should stay home. Your sick leave policies will need to support that. See information on:
