Snohomish County, WA Fire Regulations: Fireworks (2026)

RCW 70.77 (State Fireworks Law) defines consumer and display fireworks, sets statewide licensing requirements for sellers and public displays, and establishes the default statewide discharge windows: June 28 through July 5 around Independence Day and limited New Year's Eve hours. RCW 70.77.250(4) authorizes counties and cities to adopt more restrictive local rules but provides that any new local restriction must wait at least one year before taking effect. Snohomish County uses that authority through county ordinances enforced by the Sheriff's Office: the legal discharge window in unincorporated Snohomish County is reduced to July 4 only, 9:00 a.m. to 11:59 p.m. - discharge before or after that window is illegal countywide. New Year's Eve discharge in unincorporated Snohomish County is not permitted. The Southwest Urban Growth Area - the unincorporated area south of Everett/Mukilteo, north of Edmonds/Lynnwood, and around Mill Creek - has been a year-round no-discharge zone since 2020-2021, and the County Council in 2024 adopted an ordinance prohibiting the sale of fireworks in that same area beginning in summer 2025 (subject to RCW 70.77.250's one-year delay). Firecrackers, sky rockets, missile-type rockets, M-80s, dynamite, and any homemade fireworks are illegal anywhere in Washington under RCW 70.77.124 and RCW 70.77.131. Fireworks are also prohibited on all state and county park land and on federal lands. Reports of illegal discharge go to the Snohomish County Sheriff's non-emergency line (425-407-3999); 911 is reserved for active fire or injury.
