Lassen County, CA Fire Regulations: Fireworks (2026)

Lassen County is a forested-mountain and high-desert county where most land is State Responsibility Area with High and Very High wildfire risk, so fireworks are tightly restricted. CAL FIRE's Lassen-Modoc Unit states that the use of 'Safe and Sane' fireworks is allowed only within the Susanville city limits, while 'the use of fireworks in the rest of Lassen County is illegal' — even state-approved 'Safe and Sane' fireworks are illegal when used in a community where they are banned. Under California's State Fireworks Law (Health & Safety Code sections 12500 et seq.), 'dangerous' fireworks — sky rockets, bottle rockets, Roman candles, aerial shells, firecrackers, and any device that explodes, flies into the air, or moves on the ground uncontrollably — are illegal statewide without a special license, while 'safe and sane' fireworks may be used only where a local jurisdiction allows them. Because the unincorporated county does not allow them, possessing or lighting any firework outside Susanville is unlawful. CAL FIRE Fire Marshal Dennis Mathisen has warned that 'Even using Safe and Sane fireworks can be dangerous if used improperly.' On Lassen National Forest land, the U.S. Forest Service notes that fireworks and explosives are always prohibited.
