Full Breakdown
R, splits signs into exempt, regulated and prohibited categories, and digital signage falls squarely in the prohibited list. b separately bars 'electronic messaging center signs,' which covers the changeable-copy LED and LCD displays commonly used for digital billboards and reader boards. 2, which states the sign standards apply to all zones within unincorporated Island County unless otherwise stated, so there is no rural commercial or Rural Center zone exception that would let a business install a digital display. The prohibition sits alongside other bans on neon signs on building exteriors, off-premise signs, pole signs taller than 18 feet or the height of the associated building, portable signs other than permitted temporary signs, roof-mounted signs, and signs placed in a roadway or driveway visibility triangle.
5, that includes an electronic message center or animated display cannot be approved. Businesses along state highways face an additional layer of Washington State Department of Transportation sign rules under Chapter 468-66 WAC, but that state layer does not create an exception to the county's own prohibition.
Violations & Fines
Installing an electronic messaging center sign, or any sign that flashes, moves or strobes, violates section 17.03.180.R.4 outright; because these are 'prohibited signs' rather than merely unpermitted ones, Island County can deny the building permit application on its face and require removal rather than simply cite the sign as nonconforming. An installed digital sign found during inspection is treated the same as any other prohibited sign under the section's general enforcement authority in R.7.
