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

Garage-sale signage is governed by Concord's content-neutral temporary-sign regulations within Development Code Title 18. Signs must be placed exclusively on private property with the property owner's permission — posting on public utility poles, traffic-sign posts, streetlight poles, trees in the parkway, medians, or the public right-of-way is prohibited. Violations may be summarily removed by city staff without notice and can result in citations under the sign code (fines typically escalating $50/$100/$250 for repeat offenses, plus removal costs). Size is limited to residential temporary-sign standards (approximately 6 square feet, 4 feet tall), and illumination is prohibited. Signs must be removed promptly after the garage sale ends — typically within 24 to 48 hours — to avoid becoming a durable nuisance. Directional signs off-premises (e.g., at nearby intersections) still must be on private property with consent. Under Reed v. Gilbert, Concord cannot treat garage-sale signs differently from other temporary signs based on content, but size/placement/duration limits apply equally. Enforcement is complaint-driven and through routine Code Enforcement patrols on weekends. Sellers should also check that their garage-sale frequency complies with Concord's garage-sale regulations (see garage-sales category).
