Antioch, CA Garage & Yard Sales: Frequency, Duration & Permits (2026)

The Antioch Municipal Code defines GARAGE SALE, within the zoning ordinance's definitions article (AMC § 9-5.203), as the sale of predominantly used personal property from a residence, occurring as an accessory use of a residential property, for a period of no more than three consecutive days and no more than three times in a calendar year. That definition does double duty: it is both the permission and the limit. Because a garage sale is classified as an accessory use rather than a standalone commercial use, a resident does not need a separate business license or use permit to hold one, as long as it stays inside that three-day, three-times-a-year box.

The same section draws a hard line on what falls outside it. Selling unused (i.e., new) property, or running a sale longer than three consecutive days, or holding more than three sales in a calendar year, converts the activity into what the code calls RETAIL, GENERAL AND SPECIALTY. That is a commercial land use category, and residential zoning districts in Antioch do not list general retail as a permitted or accessory use. A resident who blows past the frequency or duration cap is no longer conducting an accessory garage sale under the zoning code; they are operating an unpermitted retail business out of a home, which triggers the code's general zoning enforcement and business-license requirements rather than any garage-sale-specific process.

The rule is self-enforcing through the definition itself: there is no permit application or fee tied to staying within the three-and-three limit, but there is also no administrative exception to extend it. A fourth sale in the same calendar year, or a sale that runs into a fourth day, simply does not meet the GARAGE SALE definition anymore.
