Glenn County, CA Sign Regulations: Political Signs (2026)

Glenn County regulates signs in Chapter 15.620 (Sign Standards) of the Unified Development Code. Temporary political signs are listed among the 'exempt signs' in Section 15.620.030(I), meaning they do not require a sign permit and their area is not counted toward a site's total permitted sign area. The provision sets clear limits: political signs may not exceed 'four square feet total for each property in residential categories and sixteen square feet total for each property in nonresidential categories,' campaign signs 'shall not be posted more than sixty days preceding the election,' and they 'shall be removed within fourteen days following the election.' Sign permission and placement rules in the chapter also apply - Section 15.620.020(A) requires the property owner's written consent for any regulated sign, and Section 15.620.020(D) requires signs to be located outside of county street and road rights-of-way (except by variance). For signs placed along state highways, the California Outdoor Advertising Act applies and generally exempts temporary political signs from display-permit requirements while still requiring identification and timely removal. Because content-based limits on political signs raise First Amendment issues, these durational and size limits are enforced as time, place and manner standards; questions should be directed to Glenn County Planning & Community Development Services.
