Ontario allows small garage sale directional signs on private property during the sale, but prohibits attaching them to utility poles, street trees, or traffic signs under OMC Chapter 8 and Vehicle Code 21466.5.
The Ontario Sign Code (OMC Chapter 9) treats garage sale signs as temporary, non-commercial event signs. A residential property hosting a permitted garage sale may place one on-site sign up to 4 square feet on the property where the sale takes place, and off-site directional arrows may be placed only on other private property with the owner's permission. Placement on utility poles, traffic signs, light standards, street trees, medians, fences along public right-of-way, or any City-owned property is prohibited under OMC Chapter 8 and California Vehicle Code 21466.5, which makes it unlawful to place any sign on an official traffic device. Staples, nails, and adhesive damage to public poles constitute malicious mischief under Penal Code 594. All signs must be removed within 24 hours after the sale ends. Code Enforcement and Public Works crews routinely remove violating signs, and repeat offenders can face administrative citations ranging from 100 to 500 dollars per sign.
