Full Breakdown
Under Zoning Ordinance § 7100.4.F, window signs for any nonresidential use may not cover more than 30 percent of the total window area, counting multi-pane windows as one window. A business may add one illuminated or electronic window sign, capped at four square feet and counted toward the 30 percent limit; it must be static, showing no moving images, and can only be lit during the establishment's hours of operation. These are minor signs, so no separate sign permit is required as long as the standards are met.
Violations & Fines
Exceeding the 30 percent window coverage, running an illuminated sign larger than four square feet, showing motion, or lighting it outside business hours puts the display outside the minor-sign exemption and exposes the owner to a zoning infraction.
