Dublin, CA Sign Regulations: Political Signs (2026)

Dublin does not single out 'political signs' but regulates them within the category of temporary non-commercial signs in Chapter 8.84 of the Zoning Ordinance, consistent with the First Amendment limits courts place on content-based sign rules. According to the City's Temporary Non-Commercial Signs guidance and Section 8.84.140(K), these signs may be displayed for up to 60 consecutive calendar days and must be removed within seven days following the conclusion of the event that is the subject of the sign (such as an election). Each individual sign may be no more than 16 square feet per side, with a maximum aggregate area of 80 square feet per lot. The signs are exempt from a sign permit but may be placed only on private property with the property owner's written permission. They may not be placed within the public right-of-way or attached to public property, including streets, street medians, street trees, sidewalks, utility poles, public fences, public open-space areas, or parks. Signs also cannot be placed within 660 feet of, and visible from, the right-of-way of Interstate 580 or Interstate 680. California Elections and Outdoor Advertising laws give additional protections to temporary political signs statewide, but Dublin's time, place, and size standards are the operative local rules.
