Seattle does not impose specific limits on the number of garage sales a household may hold per year, but sales that become too frequent or large may be classified as commercial activity requiring a business license.
The Seattle Municipal Code does not specify a maximum number of garage sales per year or per household. Residential garage sales are expected to be occasional in nature and incidental to the residential use of the property. There is no bright-line rule distinguishing an occasional sale from a commercial operation, but factors such as frequency, volume of merchandise, source of goods (personal vs. purchased for resale), and regularity may be considered. If SDCI determines that garage sale activity has become a regular commercial business, the property owner may be required to obtain a business license and the activity may be subject to home occupation or commercial zoning requirements. Neighborhood-organized multi-household sales and community yard sales are common and generally not subject to additional regulation.
There are no specific frequency-based violations for garage sales. However, commercial-scale operations conducted without a business license from a residential property may face enforcement for zoning violations and unlicensed business activity.
