Unlawful Activities
Permissible vs. Illegal Fireworks
Permissible fireworks may only be used when no fire restriction or ban is in effect.
Permissible Fireworks
Rule of thumb: if it stays on the ground and doesn't explode — like sparklers and ground spinners — it's generally permissible, and only when no fire restriction or ban is in effect.
Illegal Fireworks
Rule of thumb: anything that explodes or leaves the ground is most likely illegal in Colorado.
Penalty
Penalties associated with the possession and use of fireworks depend on a variety of circumstances, including location, behavior, intent, and outcome. As a result, charges can range from a petty offense to a felony.
What You'll Face Depends on Time, Place, and Manner
The consequences for illegal fireworks are not set in stone. They rise with the risk you create.
Time: Using fireworks during a fire ban, under Stage 1 or Stage 2 fire restrictions, or on a Red Flag warning day — high winds and dry air — sharply increases both the danger and your legal exposure.
Place: Near dry grass, open space, brush, or homes, a single spark can start a wildfire.
Manner: Reckless use that ignites a fire or injures someone can escalate from a minor fireworks violation to far more serious criminal charges — and to personal financial responsibility for suppression costs and property damage that can reach into the hundreds of thousands of dollars.
The safest choice on a high-risk day is not to use them at all.
Always check current fire restrictions before using any fireworks.

Pet Safety
According to our animal control officers, more dogs get lost around July 4 than any other time of the year. Keep your pets properly confined to avoid escape due to fear of fireworks. Have your dog's license and identification up to date so that in the event your pet does escape, Animal Control can facilitate a quick return.
