Full Breakdown
Aurora's Unified Development Ordinance treats every window sign, temporary and permanent alike, including "open" signs, as one combined total per property. General standard: no more than 50% coverage of any single window pane, tightened to 25% per pane in the Mixed-Use Original Aurora – Main Street (MU-OA-MS) district, and an overall cap of 200 square feet of window sign area regardless of pane count. No permit is required, but flashing or blinking window signs are not allowed. The standard applies in mixed-use zone districts; see UDO § 146-2.4.4.H.2.h for the MU-OA-MS overlay reduction.
Violations & Fines
Aurora Code Enforcement (Neighborhood Services Division) handles sign violations; excess coverage triggers a notice to remove or reduce the display, with citation for noncompliance under the UDO's general enforcement provisions.
