Austin ETJ Map: check any address against the city’s official boundaries
This is the map that actually answers the question. The boundaries below are drawn live from the City of Austin’s official jurisdiction GIS layer — the same data the city itself publishes — so it reflects current annexations and SB 2038 ETJ releases as the city posts them. Type an address (or click anywhere on the map) and we’ll check that exact point against the city’s boundary data at full precision: full-purpose city limits, limited-purpose, ETJ, or outside Austin’s jurisdiction entirely.
Tip: you can also click any point on the map to check it. Boundary fills are lightly simplified for fast loading; the address check itself queries the city’s GIS at full precision.
What the three colors mean for your land
| Status | City zoning | City property tax | Who controls platting | What it means |
|---|---|---|---|---|
| Full-purpose city limits | Yes | Yes | City of Austin | The complete city rulebook: zoning, site plan, building permits, city utilities (generally), city taxes. |
| Limited-purpose | Partial | No (full) | City of Austin | A narrow annexation category — some city regulations apply without full-purpose taxation. Rare, but it exists on the map. |
| ETJ | No | No | City of Austin (joint city–county) | No city zoning or tax, but Austin still controls subdivision platting and applies drainage/water-quality rules — including Barton Springs Zone impervious-cover limits in the southwest. Since SB 2038, many owners can petition out. |
| Outside all of it | No | No | County only | Unincorporated county — the lightest-touch regime (Texas counties cannot zone). But check other cities’ ETJs: Dripping Springs, Bee Cave, and others tile the map west and south of Austin. |
Austin’s ETJ extends up to five miles beyond the city limits (the widest band Texas law allows, reserved for cities over 100,000 population), and decades of piecemeal annexation have left the western and southeastern corridors looking like marble cake — city, ETJ, and county parcels interleaved along the same road. It is entirely normal for one tract on US-290 West to touch all three, which is why an address-level check beats eyeballing any static map.

In the ETJ? That may be worth money to you
Since Texas SB 2038 (2023), a qualifying owner can petition out of a city’s ETJ entirely — and the city has no discretion to refuse a valid petition. Release runs on a 45-day statutory clock and occurs by operation of law if the city sits on it. Out of the ETJ means county-only platting and no city development authority over the tract, which frequently changes what the land is worth to a developer. HB 2512 (effective September 1, 2025) narrowed eligibility — most standalone lots under 12 acres and single lots in 25+ lot subdivisions are now excluded — so the window matters. Start with who still qualifies in 2026, the step-by-step in how to get land out of a city’s ETJ, and what a release costs and how long it takes. Buying rather than owning? Read buying land in the Austin ETJ first.
