Rancho Cucamonga, CA Sign Regulations: Garage Sale Signs (2026)

Under Rancho Cucamonga Development Code Chapter 17.74, garage sale signs are considered temporary signs and are subject to strict placement limits. Each residence may display a modest on-property sign advertising the sale during the hours the sale is active, typically no larger than 6 square feet and not illuminated. Off-site directional signs are generally not permitted in residential neighborhoods, and attaching any sign to a utility pole, street light, traffic sign, street tree, or other public infrastructure is a violation subject to removal and potential fines under Municipal Code. Signs in the parkway strip between the sidewalk and curb are in the public right-of-way and are not allowed. Signs must be removed promptly at the conclusion of each sale day and permanently at the end of the sale; leaving old signs up after the sale can trigger Code Enforcement action. Public Works staff routinely remove illegally posted signs on weekends and may bill the owner listed on the sign for removal costs. Residents should consider neighborhood apps, online classifieds, or HOA bulletin boards as alternatives to unlawful off-site signage.
