All fireworks including Safe and Sane are banned year-round in Rancho Cucamonga. First-offense administrative fines start at 1,000 dollars, and dangerous fireworks are a misdemeanor under state law.
Rancho Cucamonga is a total-ban city for consumer fireworks. Under Municipal Code Chapter 15 and California Health and Safety Code Division 11 (State Fireworks Law), no person may possess, sell, use, give away, discharge, store, or transport any firework within city limits, including those bearing the California State Fire Marshal Safe and Sane seal. This matches neighboring Fontana, Upland, and unincorporated San Bernardino County. Enforcement peaks around Independence Day and New Years Eve when Rancho Cucamonga Police (a San Bernardino County Sheriffs contract) and the Rancho Cucamonga Fire Protection District run joint patrols and a dedicated tip line. The city also offers an anonymous online reporting portal. Administrative citations begin at 1,000 dollars for a first offense and escalate to 2,000 and 3,000 dollars for repeat violations within one year. Possession or use of dangerous fireworks such as aerial shells, M-80s, bottle rockets, or altered Safe and Sane devices is a misdemeanor under Health and Safety Code 12677 punishable by up to one year in county jail, fines up to 1,000 dollars, and civil liability for any fire damage caused. Property owners and tenants can both be cited, and parents may be liable for fines incurred by minors. Foothill homeowners face heightened enforcement because of wildfire risk in the Very High Fire Hazard Severity Zone.
