Montana Coronavirus Closures, Restrictions And Exemptions

An infographic from the CDC illustrates social distancing and mask wearing to limit the spread of COVID-19.

Updated 05/07/21

As of February 12, 2021, there is no statewide mask mandate in Montana, nor limits on business hours. However, more restrictive rules are in place in some localities.

Masks, social distancing and good sanitation practices are still recommended throughout the state.

A new Montana law signed by the governor on May 7, 2021 prohibits local governments from taking certain actions — such as those taken to prevent the spread of the coronavirus — that would affect the bottom line for businesses. As a result of the new law, both Lewis and Clark and Gallatin counties said they could no longer enforce mask mandates.

Gallatin County health officer Matt Kelly says the law will make it "pretty impossible for local health officials to address the pandemic in a meaningful way through rules that affect businesses."

Mask mandates in effect prior to the May 7 law:

  • Big Horn County
  • Fort Belknap Reservation
  • Fort Peck Reservation
  • Gallatin County
  • Hill County
  • Lake County
  • Lewis And Clark County
  • Madison County
  • Missoula County
  • Park County
  • Powell County
  • Rocky Boy's Reservation
  • Whitefish

Statewide directives:

Gatherings: “Any public gatherings or events should be managed in a way that accommodates CDC social distancing guidelines.” This removes all previous capacity limits.

Businesses: Businesses no longer have restrictions on their capacities or hours. Per the new guidelines, they “… should make reasonable efforts to develop and implement appropriate policies based on industry best practices during this emergency.” If there are no industry best practices, Gianforte’s directive points owners and managers towards "federal, state, and local regulations and guidance."

Schools: “Schools should make reasonable efforts to follow industry standards best practices recommended by the Center for Disease Control, the Office of Public Instruction.”
