As Colorado has seen a continued decline in coronavirus spread, several counties have lifted the mask mandates that swept through the Denver metro area in recent months.

Here’s a look at where and when mask mandates ended or will fall away.

Adams, Arapahoe

The Tri-County Health Department board voted to let the mask mandates for schools and public indoor places in Adams and Arapahoe counties expire Feb. 5. The board moved to end the mandates at a Jan. 31 meeting.

Tri-County also provides certain public health services in Douglas County but no longer has authority over countywide public health orders, such as mask mandates, in that county. The newly formed Douglas County Health Department has not issued a mask mandate.

Amid the change in mask policy, an announcement from Cherry Creek School District Superintendent Christopher Smith said: “Please note, the CDC still requires all passengers and drivers of school buses to wear a mask.”

Denver

The Tri-County Health decision came on the heels of Denver’s move to allow its mask mandate for most indoor public spaces to expire on Feb. 3.

Soon after, Denver Public Schools updated its mask guidance after the Denver Department of Public Health and Environment announced that its public health order requiring masks in schools will expire at the end of the day on Feb. 25, according to a Feb. 9 announcement on the school district’s website.

Masks will no longer be required but will be strongly recommended for all students, staff and visitors across DPS, the announcement said.

Jefferson

During a special meeting on Feb. 10, the Jefferson County Board of Health voted to rescind the public health order that required masks in all public indoor settings, including school and child care settings, effective 11:59 p.m. Feb. 11, according to a news release. 

The Jeffco Public Schools district had previously announced that the mask requirement would be lifted Feb. 18, but the date was later moved up to the start of Feb. 12.

Clear Creek

Clear Creek County rescinded its public health order requiring masks in all indoor places open to the public. The county commissioners, acting as the board of health, unanimously voted on Feb. 3 to rescind the order, which had been in place since Dec. 7.

Masks and COVID-19 testing at schools in the area will be optional starting Feb. 26. The Clear Creek County commissioners, again sitting as the board of health, voted unanimously to lift the requirements at their Feb. 15 meeting.

Broomfield

In recent months, Broomfield had remained one of the few places in the metro area without a broad indoor mask mandate.

Then, Broomfield announced that masks would be required indoors city- and county-wide for everyone age 2 and older starting Jan. 7 through Feb. 3.

“In response to the Marshall fire taking Avista Hospital offline, and dramatic increases in cases of omicron in Broomfield, data shows Broomfield must take action to protect the health and safety of our community,” an announcement on Broomfield’s website said.

Later, the website announced that Broomfield’s mask requirements would expire at 11:59 p.m. on Feb. 3.

That means the requirement for mask wearing in public indoor spaces in general and in schools and child care facilities were to both expire at that time, according to Carolyn Romero, Broomfield spokesperson.

Boulder

The Boulder County Board of Health voted to rescind Public Health Order 2021-08 and Public Health Order 2021-07 effective at 5 p.m. Feb. 18, according to a news release.

Public Health Order 2021-08 required all individuals 2 and older to wear masks in all indoor settings regardless of vaccination status. Public Health Order 2021-07 required masks for all child care settings, PK-12 schools and youth activities regardless of vaccination status, according to the release.
