Summary

Jefferson County prohibits all fireworks inside its county park system. Section 240.080(Q) states flatly that fireworks are prohibited in County parks, with no exception carved out for holidays, permits or supervised displays, and the Parks Department and Sheriff's Office enforce it alongside the chapter's other open-flame and weapons restrictions.

These county ordinances apply to unincorporated areas of Jefferson County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Use Of Fireworks Prohibited. All fireworks shall be prohibited in County parks.

Full Breakdown

080(Q) of the Article III park regulations, adopted under Ordinance No. 09-0347 in 2009 and amended through Ordinance No. 26-0207 in 2026, bans fireworks outright on any Jefferson County-owned, -maintained or -controlled park property. 070, defines 'fireworks' broadly as 'a device designed for a visual or audible display through the combustion of explosive or flammable compositions,' so the prohibition sweeps in consumer fireworks, novelty items and professional displays alike unless a different County authorization applies elsewhere. 080(E), which bans personal charcoal or wood grills and limits open flame to Department-provided fire devices or a permitted campsite fire.

Because the fireworks ban is written into the park-regulations article, it applies specifically to park property; it does not itself regulate fireworks sale or discharge on private property elsewhere in unincorporated Jefferson County, which falls under separate state and county fire-safety authority. 080(S).

Violations & Fines

Possessing or discharging fireworks in a Jefferson County park violates Section 240.080(Q). Park regulation violations are enforced by the Department of Parks and Recreation and the Jefferson County Sheriff's Office, and offenders can be cited, ordered to leave the park, and referred for prosecution; unauthorized weapons discharge under the related Section 240.080(B) carries the same park-property enforcement.

Frequently Asked Questions

Can I set off fireworks in a Jefferson County park on the 4th of July?
No. Section 240.080(Q) prohibits fireworks in every Jefferson County park with no holiday or special-event exception written into the rule; the ban applies to every County-owned, -maintained or -controlled park property year-round, regardless of the occasion or whether the display is supervised.
Does this fireworks ban apply outside the county parks too?
Section 240.080(Q) is written into the park-regulations article, so by its own text it governs County park property. It does not itself set rules for fireworks sale or discharge on private property elsewhere in unincorporated Jefferson County, which is addressed under separate state and county fire authority.
What counts as 'fireworks' under this park rule?
Section 240.070 defines fireworks as any device designed for a visual or audible display through the combustion of explosive or flammable compositions, a definition broad enough to cover consumer fireworks, novelty items and professional display fireworks, so nothing in that category is exempt inside a county park.
