Summary

Longmont bans discharging any fireworks on city streets, alleys, sidewalks, parks or other city property without a sparkler permit, and bans discharge from vehicles or near grassland and combustible material. Selling to or purchasing by anyone under 16 is also illegal, and only permissible fireworks like sparklers and fountains may be possessed under Municipal Code § 10.60.030.

A. Except as an authorized part of a city-conducted or city-sponsored event, it is unlawful for any person to discharge or cause to be discharged any fireworks: 1. On any city street or alley, city sidewalk, city park or other city property, unless authorized by a sparkler permit issued by the public safety chief or designee. 2. From within or upon any type of vehicle (motorized or not, moving or not). 3. In, on, or adjacent to, any grassland, combustible vegetation, or other combustible materials. 4. Upon or adjacent to the property of another so as to cause sparks, flame, smoke, heat, sound, or odor to migrate to the property of another. 5.

Full Breakdown

030 of the Longmont Municipal Code lists seven numbered prohibitions governing fireworks within city limits. Unless the display is an authorized part of a city-conducted or city-sponsored event, such as the July 4th celebration, it is unlawful to discharge fireworks on any city street, alley, sidewalk, park or other city property unless a sparkler permit has been issued by the public safety chief or designee. Discharge from within or on top of any vehicle, motorized or not, moving or not, is banned outright, as is discharge in, on, or adjacent to grassland, combustible vegetation, or other combustible materials.

Discharge that sends sparks, flame, smoke, heat, sound, or odor onto a neighbor's property is separately prohibited, protecting adjoining owners even on a resident's own lot. A sparkler permit issued for city property must carry safety conditions set by the public safety chief to limit fire risk to nearby combustibles and injury to people. Selling fireworks to anyone under 16, or purchasing fireworks while under 16, is a separate violation under subsections B and C. Subsection D lets the city manager, after consulting the public safety chief, ban discharge of even permissible fireworks during a fire ban or declared emergency, which can suspend the rule citywide on short notice during dry conditions.

Subsection E clarifies that discharging permissible fireworks on private property is otherwise lawful. Subsection F makes possession of any fireworks other than permissible fireworks unlawful outright, and subsection G authorizes any sworn police officer or firefighter to confiscate non-permissible fireworks found in plain sight. 020 defines permissible fireworks as cylindrical fountains, cone fountains, wheels, ground spinners, illuminating torches, colored fire, dipped sticks, sparklers, snakes and glow worms; everything else, including firecrackers, M-80s, aerial shells, torpedoes, skyrockets, bottle rockets and Roman candles, is unlawful to possess or discharge anywhere in the city. 040, with a 30-day advance application, a $1,000,000 insurance certificate, a $250 cash bond per location, and a $1,000 permit fee.

Violations & Fines

Violations of Title 10 offenses, including chapter 10.60, are punishable under the general penalty in section 10.02.020: a fine of up to $999.00, imprisonment of up to 180 days, or both, imposed by Longmont Municipal Court on conviction. Officers responding to illegal fireworks calls can also confiscate any fireworks that are not on the permissible list under subsection G, separate from any citation issued. Because sections B and C make both selling to and buying by minors under 16 distinct offenses, an adult supplying fireworks to a teenager and the teenager purchasing them can each be cited.

Frequently Asked Questions

Can I set off fireworks in my own Longmont backyard?
Only permissible fireworks such as sparklers, fountains, wheels and ground spinners under section 10.60.020, and only if they will not send sparks, flame, smoke, heat, sound, or odor onto a neighbor's property under section 10.60.030(A)(4). Firecrackers, bottle rockets, and anything aerial or explosive remain unlawful to possess anywhere in the city.
Can I set off fireworks in a city park?
No, not without a sparkler permit from the public safety chief or designee. Section 10.60.030(A)(1) bans discharge on any city street, alley, sidewalk, park, or other city property unless that permit has been issued, and any permit carries safety conditions on the use.
What happens if Longmont declares a fire ban during a dry summer?
The city manager can ban discharge of even permissible fireworks during a ban on fires or a declared emergency under section 10.60.030(D). That suspends the normal private-property exception citywide until the ban is lifted.
What is the penalty for illegal fireworks in Longmont?
A conviction under Title 10, which includes the fireworks chapter, carries a fine of up to $999.00, up to 180 days in jail, or both, under the general penalty in section 10.02.020. Police and fire personnel can also confiscate non-permissible fireworks on sight.
Can a business sell fireworks in Longmont?
Only from a fireworks stand under a permit issued through section 10.60.040, which requires a 30-day advance application, a state retailer license, $1,000,000 in insurance, a $250 cash bond per location, and a $1,000 permit fee, and it cannot sell to anyone under 16.
