Based on COVID-19 case count and test positivity rate, the State implemented four color-coded tiers representing levels of restrictive/less-restrictive guidelines for counties:
- Purple Tier 1 (widespread) – most non-essential indoor businesses remain closed
- Red Tier 2 (substantial) – some non-essential indoor businesses operations are closed
- Orange Tier 3 (moderate) – some business operations are open with modifications
- Yellow Tier 4 (minimal) – most business operations are open with modifications
Local county health officials may choose to be more restrictive than this framework. This framework also notes signals of concern, including impacted healthcare capacity that may lead toward state intervention. The California Department of Public Health is monitoring data (such as case count and positivity rate) and health equity measures (such as access to testing and contact tracing) to evaluate a county’s progress.

Together we can help San Mateo County move further into reopening.
Remember to wear face coverings when in public, wash your hands frequently, maintain at least six feet of distance when in public, and limit mixing with people outside of your household.
