The statewide rule
- Legal category: Safe and Sane, seal-marked, sold only during the licensed sales window around the holiday.
- Illegal statewide: bottle rockets, firecrackers, Roman candles, aerial shells, M-80s and similar — anything that leaves the ground or explodes.
- Possession or use of dangerous fireworks is charged under the fireworks provisions of the Health & Safety Code, and quantity drives whether it is an infraction, a misdemeanor, or a felony.
- Local penalties stack on top: the City of Los Angeles treats fireworks possession and use as a misdemeanor with fines and possible custody exposure.
It varies by city — check before you buy
Roughly two dozen Los Angeles County cities permit Safe and Sane sales and use on the holiday; most do not, and the City of Los Angeles bans them entirely. In San Diego County, the City of San Diego prohibits consumer fireworks. Because these lists change and enforcement is local, confirm with your own city's fire department before you buy anything — a stand across a city line does not make it legal at your house.
- Confirm your city allows Safe and Sane use, not just sales nearby.
- Use them only on the permitted dates and hours.
- Never use anything in a very high fire hazard severity zone, which covers much of the foothills.
- Buy only from a licensed, permitted stand.
If someone gets arrested
The Fourth of July is one of the busiest booking nights of the year in both counties, and it is not usually fireworks — it is DUI. Intake backs up and release times stretch. We answer 24 hours on holidays, and we cover both the LA County and San Diego County jails. See also are bail bonds open on the weekend.
