Political Signs: Martinez vs Walnut Creek

Political and other non-commercial signs are strongly protected in Martinez and may be posted on private residential property at any time, with no pre-election or post-election duration limits. Under Reed v. Town of Gilbert (2015) and California Elections Code section 18370, political signs are treated the same as other temporary non-commercial signs, generally limited to 6 square feet and 4 feet tall when freestanding.

Walnut Creek treats political signs the same as other temporary yard signs under content-neutral rules: 6 sq ft aggregate on private property. California Elections Code §18370 and constitutional free speech protections prohibit the city from imposing election-specific time limits or content restrictions.
