All fireworks, including Safe and Sane, are illegal to possess, sell, or discharge in Sunnyvale. Santa Clara County has a countywide ban and Sunnyvale enforces strict fines starting at 1000 dollars.
Sunnyvale Municipal Code Chapter 16.52 incorporates the California Fire Code and bans all consumer fireworks within city limits. This includes sparklers, fountains, and any device classified as Safe and Sane under California Health and Safety Code Section 12500. Santa Clara County adopted a countywide ban in 2019, and Sunnyvale actively enforces it with social host liability, meaning property owners can be fined even if guests set off the fireworks. The minimum administrative fine is 1000 dollars for a first offense and can exceed 2500 dollars for repeat violations. Only licensed public displays permitted through the Sunnyvale Fire Marshal are allowed. The Department of Public Safety staffs a fireworks tip line and responds aggressively around July 4th.
