Grant County, WA Sign Regulations: Digital Billboards (2026)

150(c) sets the permitting track for digital and electronic signage: "All signs utilizing animation or containing any flashing lights shall be processed as a Conditional Use," the code's more demanding discretionary review track, distinct from the routine permit issued for a static sign 32 square feet or smaller. The same subsection separately requires that "All off-premises advertising signs erected in any zoning district require an approved Discretionary Use permit (including, but not limited to, billboards)," meaning a digital billboard sitting off the site it advertises needs both the Discretionary Use permit for its off-premises status and, if it animates or flashes, would also trigger the Conditional Use standard.

Static on-premises signs larger than 32 square feet already need a Discretionary Use permit under the same subsection, so the animation and off-premises rules layer additional review on top of that baseline. 150(e) bars specific technical characteristics outright: strobe lights are prohibited unless a governmental agency requires them, neon or flashing signs are barred in every residential zone, and signs that rotate or are audible are prohibited except for traffic-safety signs installed by a government agency. 150(f)(7), but that size allowance does not relax the separate Conditional Use requirement for animation or the off-premises billboard permit.
