Short answer
In California, Caltrans' Outdoor Advertising program in Sacramento issues billboard permits. Sign companies need a yearly license of $250 or $500. Each display then costs $300 to apply and $100 a year. Signs must be 500 feet apart on freeways. No billboard may face a classified landscaped freeway or a scenic highway, and the city or county must consent first.
- Caltrans' Outdoor Advertising (ODA) program issues permits; forms go by email to oda@dot.ca.gov.

Caltrans issues billboard permits in California. A company in the billboard business needs a yearly license first. Each display then needs its own permit: $300 to apply and $100 a year. The city or county must consent before Caltrans acts. Sites next to landscaped freeways are off limits.
Who issues billboard permits in California?
The state Department of Transportation, Caltrans, runs the Outdoor Advertising program. The work sits in the Outdoor Advertising Branch of the Division of Traffic Operations. Its mailing address is Office of ODA MS-36, 1120 N Street, Sacramento. You can email oda@dot.ca.gov or call (916) 654-6473.
There is no online filing or payment system. You email the forms and mail checks. Caltrans posts an interactive map of permitted displays.
The law is the California Outdoor Advertising Act, Business and Professions Code 5200 to 5486. The rules are in Title 4, Division 6 of the state's regulations.
Do you need a license too?
Yes, if you are in the outdoor advertising business. That means placing displays or changing ads that aren't for your own business. You need the license even if a display needs no permit. Apply on Form ODA-0004.
- Up to 6 permits: $250 a year
- 7 or more permits: $500 a year
The license year runs July 1 to June 30. A renewal postmarked after June 30 owes a $100 penalty, says Caltrans' May 2025 newsletter.
Which roads need a state permit?
The state controls displays along Interstates and primary highways. Primary means the federal-aid primary system as of June 1, 1991, plus the National Highway System. That list comes from 23 U.S.C. 131.
The control zone is 660 feet from the edge of the right-of-way. Outside urban areas, displays farther out are banned if built to be read from the road. In unincorporated areas, the act also covers displays seen from any highway.
Two bans stand out:
- Landscaped freeways. No display may face a landscaped freeway. That is a stretch of 1,000 feet or more with trees or 20 feet of planting. Caltrans keeps a list of classified landscaped freeways. A review of a classification costs $500.
- Scenic highways. No billboards along official state scenic highways or scenic byways.
Where can a billboard go?
A billboard needs a business area. That is land zoned commercial or industrial, within 1,000 feet of a business. Unzoned land with business-type uses can also count. Farms and other billboards don't count as a business.

What are the digital billboard rules?
California calls a digital display a message center. The message can't change more often than once every 4 seconds. Nothing can move or appear to move. A message center must be 1,000 feet from another one on the same side of the road. That count includes on-premise message centers.
Brightness follows the general rule in Vehicle Code 21466.5. It caps a light's brightness at a multiple of the darkest point in the driver's view. There is no separate digital number.
Converting got easier in 2024. AB 1673 lets a lawful display be converted to a message center where it stands. The change still needs a new permit. It can't cost the state federal highway money.
California's 4 seconds is the low end of FHWA's 2007 range of 4 to 10 seconds.
What does a permit cost?
You pay a $300 application fee, which isn't refunded. Each display then owes $100 a year. Caltrans bills on a five-year cycle that runs from 2024 to 2028. A permit issued in 2026 pays $300 for the rest of the cycle. The current application form lists the amounts.
Caltrans' program page says companies with six or fewer permits pay on a fixed five-year cycle. Companies with seven or more may renew each year. Caltrans' FAQ page gives different cutoffs, so check with the agency.
A renewal is due by December 31 of the year a permit expires. Late renewals owe a $100 penalty per permit. A preliminary check of a site costs $200. You get $100 back as credit if you apply within a year.
Can you cut trees in front of a sign?
Only with a Caltrans encroachment permit. Cutting trees on state land without one can cost $10,000 per tree and $1,000 per shrub. It can also make the display unlawful.
To ask, file a Visibility Improvement Request on Form TR-0165. Work must be within 500 feet of the display. For tree work over $500, the city or county must consent first. If it doesn't answer in 30 days, consent is assumed. Caltrans may require replanting, per its encroachment manual.
What about nonconforming signs?
A nonconforming sign was legal when built but fails today's rules. California protects lawful billboards strongly. A lawfully built display can't be forced down without compensation under the Eminent Domain Law. That applies to the state and to cities and counties, with narrow exceptions.
Changing the ad and normal repairs are fine. Some changes count as a new display and need a new permit. These include raising it, moving it, enlarging a face, or adding lights or digital copy. Swapping wood for metal goes beyond normal upkeep.
A damaged display counts as destroyed if it stays unused 60 days after notice. It is abandoned if it stops showing current ads. An "available for lease" notice with a phone number counts as an ad.
Do you need a local permit too?
Yes. Caltrans needs written proof that the city or county consents. A local building permit or other official act will do. Without it, Caltrans must deny the application.
Cities and counties can set stricter rules on size, spacing and digital displays. A city or county can also ask Caltrans to hold a location for up to 90 days.
How do you apply for a billboard permit in California?
- Get an outdoor advertising license if you need one.
- Check that the site is not on a landscaped freeway or scenic highway.
- Confirm the site is in a business area.
- Sign a lease or other land use agreement with the owner.
- Get the local building permit or other written consent.
- Put a stake or flag at the site that names you and can be read from the road.
- Email Form ODA-0002 with a plot map, the assessor's parcel map and ownership record.
- Mail the check. Caltrans won't process the application until it arrives.
- Fix any problem within 30 days of a deficiency notice. Caltrans decides within 60 days.
- Fasten the permit plate to the front of the display, and show your name on it.
