Summary
York County caps how much of a storefront window can carry signage under § 155.935(I). In Agricultural/Open Space and Residential districts, a sign user may cover only 25% of a window's area; in Small-Scale Commercial, Commercial and Industrial, and the Lake Wylie Overlay districts, coverage can reach 50%. No permit is required for window signs in any sign district.
(I) Window sign standards.
(1) Sign standards. Window signs shall comply with the standards in Table 155.935-9: Window Signs by District.
TABLE 155.935-9: WINDOW SIGNS BY DISTRICT Standard AOS RES SSC CI LW Allowed? Yes Yes Yes Yes Yes Permit Required? No No No No No Area (Max. % per Window) 25% 25% 50% 50% 50% Sign Features Illumination No No Yes Yes Yes Manual Reader Board No No No No No Electronic Reader Board No No No No No
(2) Area and number. The cumulative area for all signs in one window pane or light may not exceed the percentage of the window area for the area standards for the district, regardless of the number of separate signs.
(3) Measurement. The area of transparent and perforated elements counts toward the sign face area without a reduction for window area not covered with sign elements.

Full Breakdown
935-9: Window Signs by District sets a numeric ceiling for every sign district the code recognizes: AOS (Agricultural/Open Space, covering the Agricultural Conservation, Rural Development, and Parks and Recreation zoning districts), RES (Residential, covering the RSF-40, RSF-30, and RMX districts), SSC (Small-Scale Commercial), CI (Commercial and Industrial), and LW (Lake Wylie Overlay). In AOS and RES districts, window signage may not exceed 25% of the window area; in SSC, CI, and LW districts the ceiling rises to 50%. 935(I)(2) makes the limit cumulative: "The cumulative area for all signs in one window pane or light may not exceed the percentage of the window area for the area standards for the district, regardless of the number of separate signs," so a shop cannot dodge the cap by hanging several smaller signs instead of one large one.
935(I)(3) states that "the area of transparent and perforated elements counts toward the sign face area without a reduction for window area not covered with sign elements," meaning a perforated vinyl decal or window film sign is measured by its full panel size, not just the visible ink. 935-9. Window signs are also barred from including a manual or electronic reader board in every district, and in AOS and RES districts illumination is prohibited outright; SSC, CI, and LW districts allow illuminated window signs.
Violations & Fines
Exceeding the window-coverage cap is a zoning violation under § 155.9999(A), a misdemeanor the County Attorney or Zoning Administrator can prosecute, carrying a fine of up to $500 per day the excess signage stays up. Because no permit is issued for window signs, code enforcement typically catches an oversized display on inspection or complaint rather than at a permit desk, and the county can also pursue it as a public nuisance under § 10.99(B).
