Wylie, TX Sign Regulations: Digital Billboards (2026)

Wylie Code of Ordinances § 22-441(a) states the city's sign article restricts new off-premise signs and minimizes the impact of existing off-premise signs because of their unique impact on public safety, visual aesthetics and quality of life. Section 22-447 turns that intent into an operative prohibition: any sign not specifically allowed by the article is prohibited, and the section expressly lists two categories that hit digital billboards head-on: subsection (b)(1) bars any changeable electronic variable message sign (CEVMS) or LED billboard that is located, relocated or upgraded along a regulated highway, and subsection (b)(12) separately prohibits billboards outright, with no exception carved out.

That double prohibition means a digital billboard cannot be installed as a new sign, and an existing off-premise billboard cannot be upgraded to add electronic or LED display technology. The nonconforming-sign article reinforces this: § 22-445(b)(1)6 lists converting a sign to animated display or moveable copy technology, including Tri-Vision technology, as an act that is not a permitted maintenance operation, so even a legacy off-premise sign loses its nonconforming status if it is electrified into a digital display. On-premise changeable-copy signage is treated separately and far more permissively under § 22-451(k), which allows static images that change no more than once every eight seconds with automatic dimming, but that provision does not reach off-premise billboards, which § 22-447 keeps off the table entirely.
