Imperial County, CA Sign Regulations: Digital Billboards (2026)

Imperial County's sign chapter singles out digital signs, also called changeable electronic variable message signs, for special treatment: unlike the standard monument, pole, or building-mounted signs the chapter otherwise permits by right (subject to size and height limits), any digital sign requires discretionary approval of a conditional use permit before it can go up. The rule applies countywide in the unincorporated area and functions as the county's practical control on electronic billboards, giving the planning commission case-by-case authority to deny, condition, or limit digital signage rather than approving it administratively.
