Governor Brown's Executive Order 21-15 rescinded all remaining Oregon Covid-19 restrictions, effective June 30. This means that agencies and programs may now allow unmasked people on site without checking their vaccination status. However, agencies and programs may choose to continue to require masks or face coverings, provided they can provide accommodations to people who can't wear masks or face coverings due to a disability. Both OHA and BOLI have put out updated guidance that speaks to this.

Here is the key piece from the June 30 OHA guidance:

There are certain settings where masks, face coverings and physical distancing may be required. 

Settings such as the ones listed below may have requirements for masks, face coverings and physical distancing. OHA recommends that individuals check requirements before accessing services in these settings: ....

In other settings where the owner or operator requires individuals to wear a mask, face covering or face shield and physical distance: 

• Individuals should be aware that some businesses, events or facilities may have mask, face covering, face shield requirements and/or physical distancing requirements and may exclude from their business, event or facility those individuals who, regardless of their vaccination status, fail to comply with those requirements.
• Individuals who have a medical condition that makes it hard to breathe or a disability that prevents the individual from wearing a mask, face covering or face shield can request an accommodation from a business, event or facility operator to enable full and equal access to services, transportation and facilities open to the public. 
• OHA recommends that businesses, events or facilities have mask, face covering, face shield requirements and/or physical distancing requirements post a sign (or signs) with those requirements in a place that is visible to all individuals entering the premises.
