Full Breakdown
Under Zoning Ordinance Section 6263, a property may swap its permitted freestanding sign for a single freeway-oriented sign instead of putting up both. That sign's area cannot exceed 300 square feet, well above the 175-square-foot cap for ordinary freestanding signs, and its height can run 10 feet above whatever base limit applies in the zone (as high as 45 feet in the C37, C38, M54 and M58 zones). Adult entertainment establishments are barred from making this substitution. The rule applies only in the unincorporated county; the City of San Diego and other cities set their own freeway-sign standards.
Violations & Fines
A freeway-oriented sign that exceeds the 300-square-foot area cap, the height bonus, or is installed by an adult entertainment establishment is a Zoning Ordinance violation. County Planning & Development Services can require removal or modification, and the property may substitute only one freeway-oriented sign per qualifying frontage.
