From the  Jefferson County Sheriff’s Office, E-mail Alert: Jefferson County clarifies the use and possession of fireworks

With the Fourth of July rapidly approaching, the Jefferson County Sheriff’s Office would like to clarify Colorado law as it applies to the use and possession of fireworks in the unincorporated areas of Jefferson County.

A good rule of thumb: any device that explodes or leaves the ground is most likely illegal in Colorado.   Illegal fireworks include but are not limited to firecrackers, cherry bombs, bottle rockets, M-80’s and Roman candles.  It is illegal to sell, use or possess non-permissible fireworks in unincorporated Jefferson County.  Additionally, all fireworks are prohibited in Jefferson County Open Space Parks, Denver Mountain Parks and Forest Service lands.

Colorado law defines permissible fireworks as any device that does not explode or leave the ground.   Examples of permissible fireworks are cylindrical or cone fountains, sparklers, toy smoke devices, snakes and glow worms.  Keep in mind; while permissible fireworks may seem harmless, they continue to account for many fireworks-related injuries each year.

To report illegal fireworks, residents may call the Jefferson County fireworks hotline at


Jefferson County deputies will strictly enforce illegal fireworks violations in the unincorporated areas of the county this coming holiday. Any person who violates the laws pertaining to the sale, possession and use of fireworks commits a class three misdemeanor and may face a fine of up to $750.  For more information on fireworks safety, visit our Web site at  The Jefferson County Sheriff’s Office wishes everyone a happy and safe Independence Day.
