Political candidates and their supporters will be permitted to place campaign signs within Vista's public right-of-way beginning September 30, 2026, according to city regulations governing the upcoming November 3 election.

Under Vista's municipal code, campaign signs may be displayed in designated public areas for a limited window—no earlier than 35 days before the election and must be taken down within five days after election day. The regulations also cap sign dimensions at six square feet per side.

City rules prohibit attaching signs to trees, utility poles, traffic control devices, concrete surfaces, or any publicly maintained infrastructure. Signs cannot be placed on roadway medians or areas intended for vehicle traffic. If a sign is positioned within a parkway strip, the property owner of that strip must provide consent. The city engineer reserves authority to remove any signs deemed a public safety hazard.

Separate criminal penalties apply to anyone who affixes campaign materials to electrical utility poles, according to warnings from San Diego Gas and Electric's legal counsel. Such actions violate California's criminal code and could result in prosecution.

Candidates should also be aware that certain areas within Vista fall under state, county, or federal jurisdiction rather than city control. State law prohibits temporary political signs within 660 feet of landscaped freeway right-of-way. Campaign organizers are responsible for determining which agency has authority over specific locations before posting signs.
