Lancaster FAQ

Can the County deny a freeway billboard already approved by Caltrans?

Generally no. The Outdoor Advertising Act preempts most local denials of off-site signs lawfully permitted by Caltrans, though the County may enforce illumination, structural, and CEQA conditions under remaining local authority.

Are on-premise signs visible from the freeway treated the same?

No. On-premise signs identifying the business at that location follow LA County Title 22.140.430 fully, including size, height, illumination, and Conditional Use Permit triggers, with no Caltrans permit required.

Los Angeles FAQ

Do I need a state permit for a sign visible from the 405?

Yes, if within 660 feet of the right-of-way. Caltrans Outdoor Advertising permits are required before LADBS will issue a city sign permit.

Can I install a new freeway-facing digital billboard?

No. Ord. 181063 banned new off-site digital billboards citywide, and Caltrans rarely approves new freeway-oriented displays outside designated Sign Districts.
