Seattle Fire Code Section 308.1.4 prohibits open-flame cooking devices and LP-gas containers larger than 1 lb on combustible balconies of multi-family buildings (3+ units) when within 10 feet of combustible construction. Electric grills are exempt. Single-family backyards have no city restrictions beyond fire-safety setbacks from buildings.
Seattle Fire Code (SFC) Section 308.1.4, adopted from IFC 308.1.4 with local amendments, bans open-flame cooking devices, including charcoal grills, on balconies and within 10 feet of combustible construction in any building containing three or more residential units. LP-gas cylinders larger than 1 lb may not be stored or used on multi-family balconies. Exception: one- and two-family dwellings; balconies served by an automatic sprinkler system; and listed electric heating elements. Single-family backyard grilling is unregulated by city code but must comply with SFC 307.4 minimum 15-foot distance for any open burn from any structure. Storage of LP-gas at residential premises: indoor storage limited to 1 lb cylinders only; outdoor cylinders up to 100 lb water capacity (typical 20 lb BBQ tank) must be at least 5 feet from doorways, windows, and openings into combustible buildings per SFC 6109.6.
First violation: $250 administrative penalty under SFC 109. Continued violation: $500-$1,000 per occurrence. Seattle Fire Marshal can issue Notice and Order to abate within 24 hours; non-compliance is a misdemeanor under SMC 22.602. Building owners often enforce stricter no-grilling policies in leases due to insurance requirements.
