Simi Valley, CA Property Maintenance: Garage Sale Rules (2026)

Ventura County has no widely published, dedicated garage-sale or yard-sale permit ordinance for its unincorporated areas, and the County's general business-license materials do not call out garage sales as a permitted activity requiring a specific license. In practice, occasional household yard sales are handled as a temporary, incidental use of residential property, which falls under the Resource Management Agency's Planning Division, the body that regulates the use of land and structures in unincorporated areas through the County's zoning ordinances. Because no specific frequency limit, hour restriction, or sign rule is published in the County's online materials for unincorporated yard sales, residents should treat sales as genuinely occasional and incidental to living on the property. Holding very frequent or continuous sales can cross the line into operating a retail business, which would require zoning clearance, a home-occupation/business review, and potentially a business license. General County standards still apply: sales should not create a public nuisance, block sidewalks or roadways, generate prohibited signage, or produce noise that violates other County rules. Given the lack of a published, parcel-specific ordinance, the most accurate course is to contact the RMA Planning Division to confirm whether a particular sale, sign, or frequency is allowed at a specific address before proceeding. Do not assume city rules (such as the City of Ventura's) apply to an unincorporated address.
