Seattle allows temporary garage sale signs on private property but prohibits placement in the public right-of-way, on utility poles, and on public property under SMC sign regulations.
Temporary signs advertising garage sales may be placed on private property without a permit, subject to general temporary sign size limits. Signs are not permitted in the public right-of-way, on street signs, utility poles, traffic signals, or any public property. The city's sign code classifies garage sale signs as temporary signs, which are allowed for limited durations. Signs should be removed promptly after the sale ends. Seattle's right-of-way regulations are enforced by SDOT, and illegally placed signs may be removed without notice. There is no specific limit on the number of signs that may be placed on private property, but they must comply with general sign size requirements for the applicable zone.
Signs placed in the public right-of-way may be removed by the city without notice. Repeated violations of right-of-way sign placement may result in fines. Failure to remove temporary signs after a sale ends may trigger property maintenance complaints.
