Vacaville, CA Property Maintenance: Garage Sale Rules (2026)

Based on a review of the published Solano County Code, there is no standalone garage-sale, yard-sale, or rummage-sale ordinance for the unincorporated area, and no county-issued garage-sale permit or numeric limit on the number of sales per year was found. This contrasts with many cities that cap residential sales (for example, a set number of days or events per year) and require a permit. In unincorporated Solano County, an occasional household garage sale of the residents' own goods is generally treated as an incidental residential activity rather than a regulated commercial use. The line the County Code does draw is in Chapter 28, the Zoning Regulations: a recurring or commercial-scale sales operation run from a home can become a 'home occupation' (Section 28.72.40), which requires a business license under Chapter 14 and must remain clearly incidental to the residential use without changing the residential or rural character of the property. A genuinely commercial, ongoing retail operation would not qualify as an incidental garage sale. Residents should also keep sale merchandise, signage, and traffic from creating a public nuisance under Chapter 10, and should not leave leftover items as an unlawful accumulation of waste (Section 23-20) or post signs in violation of county sign rules. Because the published code does not appear to set garage-sale limits, anyone planning frequent or large sales should confirm current requirements directly with the Solano County Department of Resource Management.
