Full Breakdown
Palo Alto permits political, ideological, and campaign signs on private residential property without a permit, consistent with First Amendment protections and the U.S. Supreme Court decision in Reed v. Town of Gilbert, which prohibits content-based regulation of non-commercial signs. Under the Palo Alto Municipal Code sign regulations, temporary non-commercial signs on residential property are generally limited to six square feet per sign face in single-family zones and must not exceed an overall height of about six feet. Signs may not be placed in the public right-of-way (parkstrips, medians, sidewalks, or utility poles), obstruct sight lines at driveways or intersections, or be illuminated in a way that disturbs neighbors. Signs must be maintained in good condition and removed within a reasonable time after the election or campaign concludes (commonly within 10 days). Posting signs on public property, light poles, or trees is prohibited and will be removed by Public Works.
