Sign Permit

Before installing or posting a temporary or permanent sign, businesses must obtain a sign permit. View Sign Code regulations here.

Temporary Sign Permit

There are various types of temporary signs including cold-air balloons, banners and A-frame style signs. Businesses may display temporary signs for no more than four weeks per calendar year. Signs must be displayed for a full week at a time. Businesses may choose to display a temporary sign four weeks in a row or in one-week increments throughout the course of the year.

Businesses must obtain separate permits for each sign at a location. Each temporary sign is subject to a review fee. 

When submitting a temporary sign application, you must include a location drawing that indicates where the temporary sign will be placed. In addition, a drawing or picture of the temporary sign must be submitted with the application. In most instances, temporary sign permits can be approved and issued at the time of application.

To apply for a permit, please visit the City of Naperville Permitting, Plans and Licensing Portal. The Permitting, Plans and Licensing Portal gathers all of the information needed to apply, pay for, and manage permits in one convenient place. It is designed for use on a desktop/laptop computer.
