Irving, TX Sign Regulations: Window Signs (2026)

Chapter 7 defines a window sign as one applied on or over a window, or designed primarily to be seen through a window from outside a building; the code notes that a sign painted on and visible through glass is legally a wall sign for enforcement purposes. Section 7-3(14) folds window signs into the broader "wall signs" category alongside luminous gaseous tubing, awning, canopy, and projecting signs, and subsection (c) sets the ceiling: all wall signs of any character, in aggregate area, cannot exceed twenty-five percent of the area of the largest facade of the building or lease space, with vehicle bay doors excluded from that facade calculation.

A related rule in subsection (19) singles out luminous gaseous tubing signs visible from a public right-of-way, capping them at the same twenty-five percent of window area and explicitly counting them toward the Section 7-3(14) limit. Because window signage is not broken out with its own separate cap, a storefront that already carries wall-mounted signage close to the twenty-five percent facade limit has little or no remaining allowance for window lettering, decals, or interior-illuminated glass signage. The inspections director administers permits for signs requiring one under Section 7-12, and a sign must be brought into compliance or removed if it becomes nonconforming under Section 7-5.

The Downtown Development District and Heritage Crossing Redevelopment District overlay their own twenty-five percent window-coverage standard for tenant spaces within those boundaries, confirming the citywide approach of treating window coverage as a percentage-of-area limit rather than a flat exemption.
