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

No garage-sale-sign-specific provision was located in unincorporated Lassen County's Title 18 Zoning Code. Temporary signs, including yard/garage-sale signs, are governed by the county's general sign provisions in Chapter 18.102 (section 18.102.030). Those provisions illustrate the county's small-sign approach: for example, one nonilluminated sign not larger than 3 square feet is allowed for a home occupation, and on parcels smaller than 20,000 square feet such a sign must be attached to a building and may not be freestanding, while on parcels of 20,000 square feet or larger it may be freestanding. As a practical and legal matter, temporary signs should be placed only on private property with the owner's permission and must not be located within the public road right-of-way or attached to utility poles, traffic signs, or other public infrastructure, where they can be removed by the county or Caltrans. Garage-sale signs should be taken down promptly after the sale. Because the precise size, duration, and placement limits for temporary signs are set in Chapter 18.102, confirm the current standard for your situation with Lassen County Planning and Building Services before posting signs.
