Full Breakdown
Denver's zoning code treats window signs as temporary commercial signage under Division 10.10.3.1.F. They can cover ground-level windows or walls without a permit, but coverage can't exceed 50 percent of the maximum sign area allowed for the use by right, plus the greater of 65 percent of unused permanent sign area or 60 percent of the ground-level window area, and never more than 75 square feet total. Signs must come down within 45 days, can't flash or animate, and can only use concealed-source illumination. The Zoning Administrator can approve up to 100 square feet through a Section 12.4.2 informational-notice review.
Violations & Fines
Violating the sign code is a general Code violation under DRMC § 1-13: up to a $999 fine, 300 days in jail, or both, with each day a separate offense; Community Planning and Development can also order removal.
