San Ramon, CA Garage & Yard Sales: Garage Sale Permits (2026)

San Ramon treats occasional residential garage sales as incidental to residential use and does not require a business license, permit, or fee for them. This is consistent with California Business & Professions Code 16000 exemptions for occasional casual sales that do not rise to the level of ongoing retail activity. The operational limits that keep a sale within the incidental-use classification: (1) sales must occur entirely on private property (driveway, front yard, garage - not sidewalks or public right-of-way); (2) merchandise must be primarily used household goods belonging to the resident, not newly purchased inventory for resale (resale of new goods triggers Business License requirements and potential Franchise Tax Board obligations); (3) frequency must remain occasional - see the frequency subcategory for specific limits; (4) signs must comply with garage-sale-sign rules (private property only, remove within 24 hours, max 6 sq ft). California sales tax (CDTFA, formerly BOE) has an "occasional sale" exemption for fewer than 3 events per year by non-business sellers, so most garage sales are tax-exempt. However, sales involving firearms, alcohol, tobacco, prescription drugs, motor vehicles, or other regulated goods require separate licensing. Many San Ramon neighborhoods are governed by HOAs that impose additional rules such as: limiting garage sales to community-wide sale days organized by the HOA (common in Gale Ranch, Windemere, Dougherty Valley), requiring signage approval, restricting hours, or setting up neighborhood sale dates for signage efficiency. Check your CC&Rs or HOA portal before scheduling. Multi-family/apartment tenants typically need landlord permission before holding sales in common areas. Estate sales involving a professional estate sale company that stages and prices items usually do require the estate-sale company to have a Business License, and may be subject to different CDTFA treatment.
