Fireworks may legally be sold in unincorporated Snohomish County between noon on June 28 and noon on July 6 of each year. Fireworks discharge violations are a Class 1 civil infraction punishable by a $500 penalty in accordance with SCC 30.53A.400 and SCC 10.70.110(1)(a), and subject to a court order of restitution.
Unincorporated South Snohomish County has banned the discharge of fireworks as of 2021 (map link). In the remainder of unincorporated areas of the county where fireworks may be legally discharged, they are allowed only on the Fourth of July from 9 a.m. until midnight. Snohomish Regional Fire and Rescue has also created an interactive Firework Discharge Information Map allowing you to enter street addresses to determine firework rules by location.
Jurisdictions within the county have their own regulations related to firework discharge, and many have banned fireworks. Please view the “Stay Safe and Legal this Fourth of July” flyer for more information about each jurisdiction’s rules.
