Do you need a permit for a fence in Austin, TX?
It depends on size and placement.
Fences up to 7 ft need no permit, except in a floodplain, where every fence does.
Along a public street (not an alley) the limit is 6 ft, and going higher takes a Board of Adjustment variance.
A solid fence on a property line is capped at 6 ft, or 7 ft where the grade changes at least 1 ft.
Rules last checked by a person on October 19, 2026. Guidance only; confirm with Austin before you build.

Setbacks depend on your zoning district, and a flood zone can change the permit answer. Enter your address to see both.
