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

Glenn County Code Chapter 15.620 (Sign Standards) lists the categories of exempt and permitted signs, but it does not single out 'garage sale' or 'yard sale' signs. The closest exempt categories are temporary real estate and event-type signs - for example, Section 15.620.030(L) covers temporary real estate signs (for sale, rent or lease, model home and open house signs), and Section 15.620.030(O) covers temporary 'Temporary Sales and Events' banners and signs tied to an event or grand opening, limited to a maximum aggregate area of 100 square feet per site and removed within seven days following the event. A garage sale sign that is not addressed by a specific exemption is still subject to the chapter's general provisions: Section 15.620.020(A) requires the written consent of the property owner on which any regulated sign is located, and Section 15.620.020(D) requires signs to be located outside of county street and road rights-of-way except where a variance is granted by the Planning Commission. The chapter's prohibited-sign rules (Section 15.620.040) also apply - signs that imitate traffic signs or obstruct traffic visibility are barred. Because Title 15 does not establish a dedicated garage-sale-sign permit or duration, residents should treat garage sale signs as temporary signs subject to these general rules and confirm placement with Glenn County Planning & Community Development Services.
