Governor Abbott Lifts Mask Mandate, Opens Texas 100 Percent

Governor Greg Abbott has issued an Executive Order (GA-34) lifting the mask mandate in Texas and increasing capacity of all businesses and facilities in the state to 100 percent.

This executive order rescinds most of the Governor's earlier Executive Orders related to COVID-19. Effective Wednesday, March 10, 2021, all businesses of any type may open to 100% capacity. Additionally, this order ends the statewide mask mandate in Texas. Businesses may still limit capacity or implement additional safety protocols at their own discretion.

If COVID-19 hospitalizations in any of the 22 hospital regions in Texas get above 15% of the hospital bed capacity in that region for seven straight days, a County Judge in that region may use COVID-19 mitigation strategies. However, County Judges may not impose criminal penalties for not following COVID-19 orders nor may penalties be imposed for failing to wear a face mask. If restrictions are imposed at a County level, those restrictions may not include reducing capacity to less than 50% for any type of entity.
