No permit is required for a garage sale; however, a garage sale cannot last more than three days, and each household is only allowed two per year. Garage sale signs also do not require a permit but can only be placed on private property within 24 hours of the sale and must be removed within 24 hours after the conclusion of the sale. For a complete list of the garage sale sign requirements, please see Sec. 86-233. Temporary Commercial Signs.
