Outdoor Advertising - Rules and Regulations

Unlawful signs
An unlawful sign is one which is erected and/or maintained in violation of the law. A sign is nonconforming if it was erected prior to the effective date of state law, but does not conform to the law’s requirements. The term “grandfathered” sign is often used in relation to nonconforming signs.

For a complete list of rules and regulations please see the
Outdoor Advertising Control Manual.

Signs can not be affixed to trees, painted on rock, or any other natural resources.
