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

Antioch Municipal Code, consistent with standard California practice, limits bona fide residential garage sales to a small number per household per calendar year to preserve the distinction between casual personal-property sales and ongoing retail activity. Common limits (verify current Title 3 / Chapter 5 language): up to 2 to 4 sales per household per year, with each sale lasting no more than 2 or 3 consecutive days, and sales restricted to daylight hours (commonly 8:00 a.m. to 6:00 p.m.). Frequency limits apply per residential address, not per resident — a family with multiple adults cannot individually claim separate allotments. Sales by a professional estate sale company on behalf of a resident do not count toward the resident's allotment but require the company to hold an Antioch business license. Community/neighborhood sales coordinated by an HOA may be counted as one event or as individual household sales depending on how the city treats the specific event — HOAs should confirm with the Finance/Business License division before advertising. Exceeding the frequency limit creates several legal issues: (1) the activity becomes retail requiring a business license under AMC Title 3; (2) sales must be reported and taxed under CDTFA regulations, losing the occasional-sale exemption; (3) in residential zones, ongoing retail may violate zoning (home business rules do not typically authorize open sales to the public from a residence); (4) code enforcement may issue administrative citations escalating under AMC Chapter 1-3. Complaints from neighbors about traffic, parking, or repeated events are a common trigger. HOA CC&Rs in Antioch subdivisions (Lone Tree, Deer Valley, Vineyards) frequently set stricter limits, sometimes permitting only 1–2 sales per year and requiring HOA notice.
