Garage-sale signs in Concord must be placed only on private property with owner consent and removed within 24β48 hours of the sale's end. Posting on utility poles, street signs, medians, or in the public right-of-way is prohibited and subject to summary removal and fines. Signs are limited to general temporary-sign size standards (~6 sq ft).
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 β 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 β typically within 24 to 48 hours β 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).
