Full Breakdown
Municipal Code § 23.02.1060 sets the rule: window signs, including both permanent and temporary signs, cannot exceed 25% of the window frame area in aggregate. Animated window signs are prohibited outright. A sign that conforms doesn't reduce the property's otherwise-allowed signage elsewhere. The rule also reaches indoor merchandise displays, stock-in-trade counts as a window sign if it sits within 12 inches of the window and is visible from the public right-of-way, closing the loophole of stacking product against the glass instead of posting a sign.
Violations & Fines
Window signage over the 25% cap, an animated window sign, or a stock-in-trade display within 12 inches of the glass is a sign code violation under Title 23, subject to code enforcement action requiring removal or reduction to bring the display into compliance.
