The Iowa Zoning Sign Permit is a document required by the Iowa Department of Transportation (DOT) when installing any type of sign or billboard along public roadways. This permit establishes guidelines for the size, placement, and content of the sign, as well as any other applicable regulations. It also ensures that any signage installed meets the zoning requirements of the local municipality. There are three different types of Iowa Zoning Sign Permit: temporary, permanent, and illuminated. The temporary permit allows for a sign to be installed for a period of up to 180 days. The permanent permit allows for a sign to be installed for a period of up to five years. The illuminated permit allows for a sign to be installed with lighting, provided that all applicable regulations are met.
