Title 22.140.430 of the LA County Code prohibits digital and electronic message-center billboards in all residential zones of unincorporated areas, allowing them in commercial and industrial zones only with a Conditional Use Permit and strict brightness, dwell-time, and spacing limits.
Title 22.140.430 treats digital billboards as off-site advertising structures requiring a Conditional Use Permit through the Department of Regional Planning. Residential zones including R-1, R-2, R-3, and R-A bar them outright. Commercial and industrial zones permit them subject to: maximum brightness of 0.3 foot-candles above ambient measured at 250 feet, minimum eight-second static dwell time with no animation or video, 1,000-foot spacing between digital faces, and 500-foot setback from residential zones, parks, and schools. The California Outdoor Advertising Act preempts off-site freeway-facing signs separately. Contract cities and incorporated cities maintain their own sign codes which may be stricter or permit different installations.
Operating a digital billboard without a Conditional Use Permit, exceeding brightness limits, or running animation triggers fines up to 1,000 dollars per day under Title 22.140.430(K), plus removal at the operator's expense.
