Full Breakdown
§ 19-53(a) governs electronic message centers countywide. The digital copy portion of a sign cannot exceed 75 percent of the sign's total allowable copy area, distinct from the sign face itself. In Business Use Areas, an electronic display must hold a static image for at least three seconds before switching, frame-transition effects are allowed, but flashing and true animation are prohibited outright. In Residential Use Areas the boards are banned entirely, with one narrow exception: a non-residential use's sign sitting in a residential area may carry one, but only if each image holds for at least five seconds, with animation, flashing, and frame effects all prohibited there too. 3 foot-candle ceiling; analog units may be changed manually or by remote input.
Violations & Fines
The Codes Administrator enforces the chapter's sign standards, including message center content and brightness limits, under § 19-32(f). A first violation carries a civil penalty of up to $200 with seven days to correct it, and each day a violation continues after that is a separate offense punishable by up to $2,000 per day, with the right to a hearing before the county magistrate before any fine is finalized.
