Mission Viejo, CA Sign Regulations: Political Signs (2026)

The Orange County Comprehensive Zoning Code does not single out 'political' or 'campaign' signs for special rules. Instead, Sec. 7-9-114.4 establishes a Message Neutrality policy: the County regulates signs in a content-neutral manner as to noncommercial messages protected by the First Amendment and the California Constitution. Under the Message Substitution provision, a noncommercial message -- including a political or campaign message -- may be substituted for any duly permitted commercial message or any other noncommercial message without additional approval. As a practical matter, yard-style political signs fall under the temporary sign rules in Sec. 7-9-114.8. In Single-Family Residential and Open Space districts, the total area of all temporary signs displayed at one time on a parcel may not exceed 6 sq ft (32 sq ft in other districts). Temporary signs must be unlit and unilluminated, must be made of durable material (not standard paper or cardboard), and generally may be displayed no more than 90 days. Signs of less than 6 sq ft are also exempt from permit and area limits under Sec. 7-9-114.7. No sign may be displayed without the consent of the property owner. Because these rules apply uniformly to all noncommercial messages, candidates and residents are not subject to a separate political-sign permit, but should keep signs on private property and out of the public right-of-way.
