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

In unincorporated Placer County, garage-sale and yard-sale signs fall under the general sign regulations of Placer County Code Section 17.54.170 (Signs). The county does not advertise a dedicated garage-sale permit, but temporary signs are limited in size, location and duration. Temporary window signs are limited to 25 percent of the window area and may be in place no longer than 30 days in any 60-day period. Other temporary banners, signs and materials are limited to a maximum aggregate area of 100 square feet per site and a maximum of 45 days per year. The single most important placement rule for garage-sale signs is that no sign may be placed within a public right-of-way or easement without written permission from the Placer County Department of Public Works. That means signs stapled to utility poles, attached to road signs, or staked in the roadside right-of-way are prohibited and subject to removal. Signs must be located on private property with the owner's consent. Because First Amendment law restricts content-based sign rules, the county applies its size, placement and duration limits to temporary signs generally rather than singling out garage-sale messages. Property owners planning a garage sale should keep signs on private property, remove them promptly after the sale, and consult the full text of Section 17.54.170 or CDRA Planning for the specific limits in their zone district and in the Tahoe Basin, where additional standards apply.
