Walnut Creek, CA Garage & Yard Sales: Garage Sale Permits (2026)

Walnut Creek Municipal Code Chapter 5-3 treats residential garage sales (also called yard sales, estate sales, or moving sales) as incidental to residential use and exempt from business license requirements when conducted within specified limits. Rules: (1) maximum 2-3 garage sale events per calendar year per residential address (varies by interpretation; enforcement discretion applied to clearly-commercial operations); (2) each event limited to 3 consecutive days; (3) sales must occur on private property (driveway, front yard, garage) — not in public rights-of-way; (4) hours limited to daylight — typical 8 AM to sunset, no amplified sound; (5) items sold must be personal household property, not purchased for resale. Estate sales conducted by professional estate liquidators following a death or major downsizing event are typically treated as one-time and permitted. Operations exceeding the frequency limits or featuring goods clearly purchased for resale (new merchandise, identical multiples, commercial quantities) are deemed commercial retail requiring a city business license and appropriate zoning — typically not permitted in residential zones. Sales tax applies to garage sale proceeds exceeding $1,500/year under California BOE Regulation 1595 (occasional sales exemption). Local complaints about traffic, parking, or signage may trigger code enforcement review.
