Sign Codes and Permits

This information is not intended to be all inclusive of codes relating to commercial signs in the city; rather it provides general information for the most common signs used by businesses. View the full sign code.

Permanent Sign Requirements

Sign Permit is required from the city of Aurora through a licensed sign contractor before any permanent signs are erected in the city. This includes signs that are moved or altered from what was approved on the original permit. A permit is not required for text changes if there is no change to the physical design, sign area, or other changes.

Types of Signs Allowed for Commercial, Industrial and Institutional Use
Only wall, projecting blade, monument and window signs are allowed.

Total Number of Signs Allowed
A total of five permanent signs are allowed per business unless a waiver has been granted or specified on a site plan. This includes permanent window signs.

Amount of Sign Area
The total amount of sign area for each business depends on the amount of building frontage for each business. Contact the Permit Center at 303.739.7420 or email [email protected] for detailed information pertaining to your location.

Permanent Sign Submittal Requirements
Licensed contractors may submit for sign permits by applying online. All submittals must include a landlord approval or Design Review Committee approval, sign plans (showing measurements of all signs to be installed) and structural engineered plans (for all monument signs over 7 feet only).
