Mariposa County, CA Sign Regulations: Political Signs (2026)

Mariposa County Code section 17.336.060 sets the standards that 'shall apply to all political signs throughout Mariposa County, including in planning areas, unless there are specific standards established for a political sign in the adopted area plan for a planning area.' A political sign is defined as one 'intended to encourage a particular vote in a scheduled election,' also called a temporary political sign per section 5405.3 of the State Outdoor Advertising Act. The conditions are: no political sign within the right-of-way of any state highway; none within the easement or right-of-way of, or over any portion of, a county-maintained road; none that impairs traffic safety, sight distance, or traffic flow; none on county property; none placed 'sooner than ninety (90) days prior to the scheduled election'; all political signs 'removed within ten (10) days after the election'; 'No individual political sign shall be larger than thirty-two (32) square feet'; and signs may contain no outline tubing, flashing lights, or moving parts. Signs may only be placed on your own property — the County's zoning ordinance does not allow off-site signs. California Government Code 53074 also generally limits how cities and counties regulate political-sign placement.
