San Leandro, CA Sign Regulations: Political Signs (2026)

Per the City's Campaign Signs page and San Leandro Zoning Code Chapter 4.12 (Signs), the maximum allowable size of a political sign is 16 square feet. Before installing any temporary political sign anywhere in the City, the person installing the sign — or the person on whose behalf the signs are installed — must file a Declaration of Intent with the City Clerk (or Zoning Enforcement Official's designee) at least two days prior to installation. The declaration includes an agreement to remove non-compliant signs and to pay the City's removal costs. Signs are allowed on private property with the owner's consent but are prohibited on all city-owned property (parks, parkways, utility poles, medians, etc.). For Caltrans rights-of-way, a separate Statement of Responsibility must be filed with the State Department of Transportation; signs may be posted no sooner than 90 days before the election and must be removed within 10 days afterward, with no signs allowed within highway rights-of-way or within 660 feet of a Landscaped Freeway. For HOA residents, California Civil Code §4710 (Davis-Stirling Act) preempts HOA bans on noncommercial signs up to 9 sq ft (and flags/banners up to 15 sq ft) made of paper, cardboard, cloth, plastic, or fabric within the owner's separate interest.
