Full Breakdown
Window signs are defined in Sec. " Under Table VIII-11-8 (Window Sign Standards), window signs are permitted outright in every zoning district from residential (A-G, R, R-1, R-1(B), R-2, R-2(B)) through the heaviest industrial districts (M-2, M-3), and in none of them does the unified government require a sign permit for them. " There is no numeric height limit (the table lists height as not applicable) and the property line setback tracks whatever setback applies to the principal building in that zoning district (marked "Z" for the applicable zoning district standard).
Digital display and internal or external illumination are barred in the lowest-intensity residential and office districts (A-G through C-O) but permitted starting in the C-1/TND T-5 commercial districts and up through M-2/M-3. Critically, Sec. states window signs "are counted toward the maximum sign area, but not the maximum number of signs, in the sign allocation system (section 27-727)" — so a business cannot post unlimited window signs, but there is no per-window or per-storefront count limit, only the aggregate square footage that ties back into the district's overall attached-sign area allocation under Sec. 27-727.
Violations & Fines
The code does not print a standalone penalty schedule inside Sec. 27-728, but Sec. 27-723 requires sign permits, inspections and bonds for signs that need them, and unpermitted attached signage exceeding the window sign area cap or displayed on the exterior glass face is enforced through the unified government's general sign-permit and code-enforcement process rather than a window-sign-specific fine.
