Summary
Round Rock caps window signage in its Downtown Special Area at 50% of window area per building elevation, and bars internal illumination except for a 2-square-foot incidental sign such as an 'Open' sign.
Window signs can cover up to 50% of window area on an elevation; may not be illuminated with the exception of a 2 sq. ft. incidental sign (typically used for a small "Open" sign).
Full Breakdown
The cap applies inside the Downtown (DT) Special Area, the historic core near IH-35, where the city layers extra sign standards on top of the citywide Unified Development Code's Article IX signs rules to protect the pedestrian-scaled streetscape. A window sign can fill up to half of the glazed area on any one building elevation. Internally illuminated window signs are barred outright, with one narrow carve-out: a single incidental sign of 2 square feet or less, such as a lit 'Open' placard. Planning and Development Services reviews downtown sign permits against these standards before installation.
Violations & Fines
Installing an oversized or internally lit window display without an approved sign permit is a UDC violation; Planning and Development Services can require removal or resizing before approval.
