Boulder County reinstates mask mandate due to Delta variant concerns

Regardless of vaccination status, all residents of Boulder County are now required to wear a face covering while indoors


The Delta variant has been found to be more than twice as contagious as the original COVID-19 strain.

Boulder County officially reinstated a universal mask mandate for public indoor buildings beginning on September 3rd at 5:00 pm. This is required for all county residents ages two and older.

Public Health Order 2021-08, issued by Boulder County Public Health, requires masks during high transmission rates according to the Centers for Disease Control and Prevention (CDC)’s Data Tracker. The ongoing Delta variant surge meets these standards.

According to Boulder County’s published announcement on September 2nd, public indoor spaces “[include] but are not limited to public transportation, private and public offices, retail stores, restaurants, bars, event centers, gyms, recreation centers, and manufacturing facilities”.

It does not apply to private or outdoor spaces. Indoors and in public, however, this mask order does not change based on vaccination status. 

Boulder County Public Health Executive Director Camille Rodriguez said, “By adopting a universal mask order now, we can preserve our healthcare system resources, protect the health of our community, and prevent hugely impactful capacity and social distancing restrictions.”

N95, KN95, and any cloth masks that comply with the CDC’s mask guidelines can be used indoors.
