Seattle does not impose specific time-of-day restrictions on garage sales, but the noise ordinance (SMC 25.08) establishes quiet hours that effectively limit early morning and late evening sale activity in residential areas.
The Seattle Municipal Code does not specify permitted hours for garage sales. However, the noise ordinance (SMC 25.08) establishes residential quiet hours from 10 PM to 7 AM on weekdays and 10 PM to 9 AM on weekends and holidays. Garage sale activity that generates noise during these hours could trigger complaints and enforcement. As a practical matter, most garage sales operate during daylight hours, typically from 8 or 9 AM to 4 or 5 PM. Early-morning setup and late-evening activity should be conducted quietly to avoid noise complaints from neighbors. Sales are typically held on weekends but weekday sales are also permitted. There are no restrictions on which days of the week a garage sale may be held.
While there are no garage-sale-specific time violations, noise generated during residential quiet hours (10 PM to 7 AM weekdays, 10 PM to 9 AM weekends) can result in noise ordinance violations with fines. Neighbor complaints about early or late activity are handled through the noise code.
