Ontario, CA Sign Regulations: Garage Sale Signs (2026)

City Code Sec. 04 permits exactly one double-faced sign at the property where the sale is held, capped at six square feet on any one side, and that sign may be posted only on the days of the sale itself, meaning it must come down once the sale ends each day the ordinance is read to require removal outside the permitted sale window. This sign rule sits inside a broader garage-sale chapter San Bernardino County residents in Ontario should know: Sec. m. Sec. 07 bars selling anything but the seller's own personal property, meaning new merchandise or consigned resale items cannot be offered.

Sec. 08 confines garage and yard sales to properties owned and permitted for residential use, so a sale, and its sign, cannot be run from a commercial or industrial parcel. Sec. 06 puts enforcement in the hands of the Police Department and any City officer charged with enforcing City laws, and requires sellers to arrange merchandise so fire, police, and health officials can access the sale at all times. A licensed nonprofit rummage sale under a temporary use permit (Title 9, Chapter 1, Article 11) is exempt from this chapter's sign and frequency limits, per the Sec. 01 definition.
