Sammamish, WA Fire Regulations: Outdoor Burning (2026)

Outdoor burning of yard waste and debris is not allowed in Sammamish. The city falls under the jurisdiction of the Puget Sound Clean Air Agency (PSCAA), which regulates outdoor burning across King, Kitsap, Pierce, and Snohomish Counties. In PSCAA's urbanized areas, which include Sammamish, burning yard waste is not allowed at any time. Land-clearing fires are prohibited across all four counties, and burning trash, using burn barrels, or trying to 'smoke out' a neighbor is always illegal. The only outdoor fires generally permitted are small recreational fires (campfires, charcoal grills, fire pits, and chimineas) that do not exceed three feet in diameter or two feet in height and burn only charcoal, dried firewood, or manufactured firelogs. Eastside Fire & Rescue, the fire authority serving Sammamish, additionally imposes a seasonal outdoor-burning moratorium from June 15 through September 30 each year and may require a free burn permit for open recreational fires. Residential burning of natural vegetation, where allowed at all under a permit, is restricted to natural leaves, clippings, and yard refuse and prohibits rubber, asphalt, petroleum products, plastics, garbage, and dead animals. Because Sammamish is in an urbanized no-burn zone, residents should compost or dispose of yard waste rather than burn it.
