If you want to put up an advertising display, you need to apply for a permit by submitting an application to the director or someone they've authorized.

If you want to put up an advertising sign, you need to apply using a form from the director. Your application must include your name, address, a description of the land where the sign will go, and a diagram showing exactly where the sign will be placed to make sure it's easy to find and identify.

If you want to put up an advertising display, you need written consent from both the property owner or controller and the local government. If the city or county asks, the department won't give a permit to anyone else for up to 90 days while awaiting this consent. An extra 30 days might be added if the local government shows good reason for the delay. The department's decision to grant or deny this extra time is final and presumed correct.

When you apply for a permit to put up a display, you need to include details about the display, such as what it's made of, how big it is, what it's about, and how you plan to set it up.

If you're in the business of outdoor advertising and applying for a permit, your application must include your license number, which is assigned by the director.

If you submit a complete application for an advertising display that complies with all relevant laws and pay the required fee, the director or their agent will give you a permit within 10 days. This permit allows you to keep your display up until the end of the current calendar year plus another four years.

If you get a permit to put up an advertising display, you can change the ad's content without needing a new permit or paying more fees. However, having the permit doesn't mean you can ignore local zoning laws. The owner has to follow those rules, and the county can enforce them.

This law requires the director to set permit renewals to happen every five years. If someone misses the renewal deadline, there's a one-year grace period to renew late, but any permits not renewed by January 1, 1993, are canceled for good.

If you have a permit under this law, it will have an ID number and allow you to put up the specific advertising display you applied for.

In California, you can't put up an advertising display without attaching an ID number plate to it. If there's no plate, it's assumed that the sign is illegally placed, and it can be taken down.

This law states that the director will provide identification number plates. Each plate will display the identification number specific to the advertising display it is assigned to.

This law applies to billboards that were placed legally before November 7, 1967, next to major highways within city limits, and didn't need a permit before. If you get a permit for such a billboard now, it's considered a renewal of the original permit for that existing billboard.

This law states that if a highway in a city becomes an interstate or primary highway, any advertising signs next to it must follow specific regulations. The signs will be treated as if they've been next to such highways all along. Once notified of the highway change, sign owners have 30 days to inform the director of their sign's location using a specific form. The director will then issue a permit for the sign if the owner pays necessary fees, treating it like a renewal for an already existing sign.

This section says that even if you get a permit for putting up an advertisement, you still have to follow local city or county rules. Getting the permit doesn't let you ignore those rules.
