Castle Rock allows only Colorado 'permissible' (ground-based) fireworks, and only on July 4 between 8 a.m. and 10 p.m. Aerial and audible devices like firecrackers are illegal. During fire restrictions, all fireworks are banned.
Under Town Code 9.16.030, no person shall use permissible fireworks except on the 4th of July between 8 a.m. and 10 p.m. Colorado law (CRS 12-28-101) limits 'permissible fireworks' to ground-based fountains, sparklers, ground spinners, and similar small devices; aerial devices and firecrackers are prohibited statewide. When the Town is under Stage 1 or Stage 2 fire restrictions, all personal and professional fireworks are banned regardless of date. Front-Range fire bans are common in dry summers, so a July restriction can nullify even July-4 use.
Fire-restriction violations carry up to a $1,000 fine, 180 days in jail, or both. Report fireworks to Castle Rock Police dispatch.
