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

Garage-sale and open-house signage in unincorporated Mono County is governed by the General Plan Land Use Element, Chapter 07 - Signs. Section 07.020(9) states that temporary signs in residentially designated areas shall be limited to garage sales and open-house signs and shall be limited to 3 square feet in size. The same provision sets a timing rule for temporary event and holiday signage: banners, signs, or decorative materials may not be erected more than 30 days preceding the event and shall be removed upon its conclusion. For a garage sale or open house, that means signage should go up shortly before the sale and come down promptly afterward, and each sign may not exceed 3 sq ft. The provision distinguishes these temporary commercial-style residential signs from political and noncommercial-message signs, which are expressly exempted from the paragraph's restrictions. The County does not require a sign permit for these small temporary residential signs. Because Mono County combines its General Plan and Zoning Code into a single document, these standards apply countywide across the unincorporated area; sign placement within a state-highway right-of-way is separately restricted by state law and Caltrans.
