Boulder County Fire Restrictions

Boulder County, Colo. - Sheriff Curtis Johnson has enacted Stage 1 fire restrictions, effective noon, March 30, 2026, for unincorporated areas of western Boulder County.

Reference the Boulder County site for the most up-to-date and official information. 

Although the eastern part of unincorporated Boulder County was already under Stage 1 fire restrictions as of December 22, 2025, the unseasonably hot and dry weather has resulted in the need for restrictions throughout the entirety of unincorporated Boulder County. Fire restrictions are being implemented due to increasing fire danger, lack of moisture, and the forecast for hot temperatures. The fire restrictions will be in effect until the fire danger in our fuels and weather has consistently subsided.

Anyone found in violation of fire restrictions may be convicted of a civil infraction and may be subject to a $500 fine. Higher fines may be imposed for subsequent offenses.

The fire restrictions PROHIBIT:

  • Building, maintaining, attending, or using an open fire, campfire, or stove fire on public lands. This includes charcoal barbecues and grills;
  • Fireworks sales, use, and possession, including permissible fireworks;
