The sign cannot exceed three square feet (432 square inches), calculated as height times width under § 25.3.2.2.1. The sign must be unlit and built from non-flashing, non-reflective materials: no illuminated or animated signage, unlike the larger freestanding signs allowed for ordinary businesses in commercial districts.
