Alameda County allows political signs on private property with First Amendment protections. Signs in public right-of-way are prohibited. No permit required for residential political signs.
Alameda County permits political signs on private residential property in unincorporated areas under First Amendment protections established by Reed v. Town of Gilbert (2015), which prohibits content-based sign regulation. No permit is required for temporary political signs on private property. Size and setback limits in the county zoning code apply based on zoning district, typically allowing signs under 6 square feet in residential zones. Political signs are prohibited in the public right-of-way (sidewalks, medians, utility poles) and can be removed by Public Works without notice. Signs must be removed within a reasonable time after the election, typically 10 days. HOA restrictions are limited by California Civil Code 4710.
