Bannock County, ID Sign Regulations: Digital Billboards (2026)

Bannock County Code § 17.52.470(M) sets the operating limits for changeable message billboards under the county's off-premise sign standards. The transition between messages must be instantaneous or a fade, never flashing, and must complete within two seconds; each message must then hold for a minimum of eight seconds before changing again. Any billboard face built with LED or similar changeable-message technology also needs a light sensor that dims the display as ambient light drops, enforced through the Planning and Development Services site plan process. Digital billboards share the same siting limits as standard off-premise billboards under 17.52.470(N): they are allowed only in the Agricultural, Recreation, Industrial and Light Industrial zoning districts, and must sit at least 250 feet from any residential district.

A new digital billboard also triggers the neighbor notification procedure in 17.52.470(P): the applicant files a site plan and letter of intent with Planning and Development Services, staff mails notice to owners within 300 feet, and those owners get 15 calendar days to comment before the director decides. A denied or conditioned applicant can appeal under Section 17.56.130 within 14 days. Billboards may not exceed 35 feet in height above the roadway grade to the bottom of the sign face, and no off-premise billboard may sit within 500 feet of another one along the same road.
