Full Breakdown
Austin City Code Sec. 25-10-123 governs freeway-facing signage inside an expressway corridor sign district, one of the sign districts mapped under Chapter 25-10 for property fronting Austin's controlled-access highways. A lot gets one freestanding sign as of right; a second or third freestanding sign needs a separate permit under Section 25-10-131 (Additional Freestanding Signs Permitted). 7 square feet of sign area per linear foot of frontage, capped at 300 square feet regardless of frontage length. Height is capped at the greater of 35 feet above the pavement grade of the frontage street or 20 feet above the ground at the sign's own base, a formula that lets a sign builder use whichever reference point produces the taller allowance on sloped sites.
A property owner may substitute a roof sign for the freestanding sign under Section 25-10-132 (Roof Sign Instead Of Freestanding Sign). Wall signs are allowed outright, and one flag is permitted for each curb cut serving the lot. For any sign that is not a freestanding sign or a roof sign, the combined sign area on the lot cannot exceed 20 percent of the facade area of the building's first 15 feet. The building official administers the sign chapter under Section 25-10-21, issuing sign permits, inspecting installations, and pursuing legal action, including injunctions, against signs that exceed these thresholds without an approved modification.
Violations & Fines
The building official enforces Chapter 25-10 under Section 25-10-21, which authorizes permit issuance, compliance inspections, and legal proceedings, including injunctive relief, against a sign installed without a permit or over the district's size and height caps. An oversized or overheight sign can also be denied a modification: Section 25-10-22 lets the building official approve up to a 20 percent size or height increase only on a showing of practical difficulty and no loss of public safety, so anything beyond that margin must be brought into compliance or removed.
