Plumas County, CA Sign Regulations: Garage Sale Signs (2026)

Unincorporated Plumas County regulates signs generally through Title 9, Chapter 2, Article 4, Sec. 9-2.416 (Signs), with district sections such as Sec. 9-2.1807 (R-20) referencing those general requirements. There is no separate county ordinance specifically governing garage-sale or yard-sale signs; they are treated as temporary signs subject to the general standards (which include limits keyed to the zone). The most important practical limits come from placement: temporary signs may not be placed in the public road right-of-way or where they obstruct traffic sight distance, and signs within the right-of-way of a state highway are prohibited and subject to removal under California's Outdoor Advertising Act (Business & Professions Code Sec. 5405.3 and related sections), enforced by Caltrans. Best practice in Plumas County is to place a garage-sale sign on your own private property (or with the consent of the owner where it is posted), keep it out of the roadway and clear of intersections, and remove it promptly after the sale. Because the county's general sign standards and any size/duration limits are set in Sec. 9-2.416, and rural mountain road right-of-ways can be wide, confirm specifics with the Plumas County Planning Department before posting off-site signs.
