Unincorporated Sierra County has no ordinance regulating garage-sale or yard-sale signs on private property. The county code contains no temporary-sign permit or size rule. Signs may not be placed in a state highway right-of-way, which is controlled by California's Outdoor Advertising Act and Caltrans.
The Sierra County Code (current through Ordinance 1145, April 2026) contains no temporary-sign or garage-sale-sign regulation. The Zoning title (Title 15) does not establish permits, durations, or size limits for yard-sale, garage-sale, directional, or other temporary signs, and the only sign reference in the code (SCC 11.04.050) concerns official traffic and parking signs. As a result, there is no county permit requirement or fee for putting up garage-sale signs on your own property. The principal legal constraint comes from California's State Outdoor Advertising Act, administered by Caltrans, which prohibits placing signs within the right-of-way of a state highway; signs placed in a highway right-of-way may be removed by Caltrans. On county roads, signs that obstruct sight distance, traffic control devices, or the traveled way can also be removed as a safety hazard, and any sign that is injurious to safety or obstructs free use of a road could be treated as a public nuisance under SCC 8.20.030. Best practice in unincorporated Sierra County is to keep garage-sale signs on private property with the owner's permission, set back from the roadway, remove them promptly after the sale, and never attach them to utility poles, street signs, or place them in the public right-of-way. Confirm any specific rules with the Sierra County Planning or Public Works department.
No county garage-sale-sign penalty exists because there is no such ordinance. However, signs placed in a state highway right-of-way may be removed by Caltrans, and signs that obstruct a roadway or sight lines on county roads can be removed as a safety hazard or abated as a public nuisance under SCC 8.20.030.
