Summary
Window and interior display signs in Maricopa's commercial and industrial districts can't exceed 50 percent of the glass area they're mounted behind, per Maricopa City Code § 18.115.090(E)(1). The limit stacks with the district's 100-square-foot aggregate sign cap, a zoning permit is required unless the display is exempt painted/vinyl glass signage, and the zoning administrator can order illegal window signage removed.
For all signs within the commercial and industrial zoning districts the following regulations shall apply... A. Total Signage. 2. The combined total aggregate sign area of all signs for any one organization in commercial, mixed-use, office and industrial zoning districts shall not exceed 100 square feet... E. Window and Interior Display Signage. 1. The total aggregate area of all window and interior display signs shall not exceed 50 percent of the total area of the windows through which they are visible.

Full Breakdown
090(A)(2) sets a 100-square-foot ceiling on the combined aggregate sign area for any one organization in commercial, mixed-use, office and industrial districts, so a business must fit its window graphics within both the 50 percent window-coverage line and that overall total. 090. 190(A)(1) authorizes 'the zoning administrator, or other designated city official' to require removal of all illegal signs or legal signs placed in prohibited locations.
Violations & Fines
Window signage over the 50 percent glass-coverage cap, or displayed without the required zoning permit, is an illegal sign the zoning administrator can order removed under § 18.115.190(A)(1). Because Title 18 violations run through the citywide code enforcement track at Maricopa City Code § 1.10.010(B), a business can instead be cited civilly: $100 per day for a first offense, $200 for a second, $400 for any subsequent offense, with a default judgment of up to $2,500 per violation and a lien recorded with the Pinal County recorder if unpaid.
