On an Austin sign job, the first step is finding the sign district. Chapter 25-10 of the Land Development Code sorts land into nine sign districts, and most of them set their own limits for freestanding sign area, height and wall-sign area. The historic and low-density residential districts work differently: commission review in one, mainly exempt signs in the other. The same sign on the same lot can be legal in one district and far too big in the next. This guide shows how Austin decides the district, then runs one invented lot through four of them.
How Austin assigns a district
Section 25-10-81 of Austin's sign regulations lists the districts “in the following hierarchy, with the historic sign district as the first district and the commercial sign district as the last district.” In order, they are:
- Historic: a designated historic landmark or historic district, or a National Register District.
- Expressway corridor: land within 200 feet of the street right-of-way of IH-35, and of the limited-access portions of U.S. 183, U.S. 290 and State Highway 71.
- Scenic roadway: Hill Country Roadway corridors and land within 200 feet of a scenic arterial, among others.
- Neighborhood: traditional neighborhood zoning and certain neighborhood-plan special uses.
- Low-density residential: zoning more restrictive than SF-6.
- Multifamily residential: SF-6, MF-1 through MF-6, MH, NO, AG and DR zoning.
- Neighborhood commercial: LO, LR, CR and W/LO zoning.
- Downtown: CBD and DMU zoning.
- Commercial: “land that is not in any other sign district.”
The order matters because a lot can qualify for more than one. Section 25-10-82 settles it: “If a sign is located in more than one sign district, the regulations for the sign district that first appears in the hierarchy described in Section 25-10-81 (Sign Districts Described And Established) apply to the sign.” So a lot zoned CBD that also sits within 200 feet of the IH-35 right-of-way is regulated as expressway corridor, not downtown, because expressway corridor is second on the list and downtown is eighth. If that lot were also in a National Register District, the historic rules would win over both.
The zoning map alone does not answer the question; you also need the distance to certain highways and any historic designation. And “commercial” is the catch-all at the bottom, not a zoning label, so a lot lands there only after it has missed every other district.
One invented lot, four districts
The lot below is made up. It has 150 feet of street frontage and sits level with the street, so “above frontage street pavement grade” and “above grade at the base of the sign” start from the same point. Its building has a front wall 60 feet wide and at least 15 feet tall, and we count only that wall as the facade, so the facade area within the first 15 feet is 60 × 15 = 900 square feet. The code does not define “facade area,” so a reviewer may count it differently. Here is what each district allows, from sections 25-10-123, 25-10-128, 25-10-129 and 25-10-130:
| Sign district | Freestanding sign area | Freestanding height | Other signs (wall and similar) |
|---|---|---|---|
| Expressway corridor (§ 25-10-123) | Lesser of 0.7 × 150 = 105 or 300 → 105 sq ft | Greater of 35 ft above the street or 20 ft above the base → 35 ft | 20% of 900 → 180 sq ft |
| Commercial (§ 25-10-130) | Lesser of 0.7 × 150 = 105 or 200 → 105 sq ft | Greater of 30 ft above the street or 6 ft above the base → 30 ft | 20% of 900 → 180 sq ft |
| Downtown (§ 25-10-129) | Lesser of 0.5 × 150 = 75 or 200 → 75 sq ft | 6 ft, flat | 20% of 900 → 180 sq ft, including any projecting sign |
| Neighborhood commercial (§ 25-10-128) | Lesser of 0.3 × 150 = 45 or 100 → 45 sq ft | Greater of 20 ft above the street or 6 ft above the base → 20 ft | 10% of 900 → 90 sq ft |
A freestanding sign that is legal at 105 square feet and 35 feet tall on the expressway is capped at 45 square feet and 20 feet under neighborhood commercial, and at 75 square feet and 6 feet tall downtown. Wall-sign area halves, from 180 to 90 square feet, between the other three districts and neighborhood commercial.
Two details differ. The commercial district's 200-square-foot cap applies to “a sign other than a multi-tenant sign”; a multi-tenant sign gets 250. And the wording of the wall-sign base differs slightly: expressway corridor, downtown and commercial use “the facade area of the first 15 feet of the building,” while neighborhood commercial says “the facade area of the first 15 feet of building height.” The code does not say whether the two phrasings produce different areas, so ask the reviewer which one they apply.
What the downtown district adds
Downtown allows a wall sign to be a projecting sign, with its own limits in section 25-10-129(D): one projecting sign per building facade, no more than 35 square feet, and a projection no more than “the lesser of: (a) six feet; or (b) a distance equal to two-thirds the width of the abutting sidewalk.” On an invented 9-foot sidewalk, two-thirds is 6 feet, so the 6-foot limit and the sidewalk limit happen to match. On a 6-foot sidewalk, the sign may project only 4 feet. A sign projecting over state right-of-way also needs the state's approval.
The record to keep
| Field | What to write down |
|---|---|
| Zoning | Base zoning and any combining districts, with the map source and date. |
| Highway distance | Distance from the lot to the IH-35, U.S. 183, U.S. 290 or SH 71 right-of-way, if any is close. |
| Historic status | Designated landmark, designated historic district or National Register District, or none. |
| District applied | The first district in the section 25-10-81 order that the lot falls into. |
| Inputs | Street frontage, facade area within the first 15 feet, and grade at the street and at the sign base. |

This is general research guidance, not a permit decision for any property. The lot is invented. We read chapter 25-10 on September 28, 2026; the city controls current requirements, and a variance, an additional-freestanding-sign provision or historic review can change the answer for a specific site.
