Los Angeles FAQ
Can I convert my existing billboard to digital?
Only if your billboard sits inside an approved Sign District. Outside those districts, LAMC §14.4 and Ord. 181063 prohibit any digital conversion.
Are existing digital billboards still legal?
Yes. Boards installed before the 2008 ban are grandfathered as legal nonconforming uses, but cannot be relocated, expanded, or rebuilt without losing that status.
Norwalk FAQ
Can a business install a digital billboard on its commercial lot?
Only with a Conditional Use Permit from Regional Planning, plus compliance with brightness, dwell-time, spacing, and residential setback limits in Title 22.140.430. The hearing process takes several months.
Are freeway-facing digital billboards regulated by the County?
Off-site freeway-facing billboards fall under the California Outdoor Advertising Act, which preempts most local sign rules. Caltrans and the State permit those, not the County, though the County still regulates lighting impacts.
