Austin, TX Fence Regulations: Neighbor Fence Rules (2026)

Austin's fence rules sit in the accessory-use chapter of the Land Development Code, and they turn on whether a fence is solid or ornamental. Sec. 25-2-899(B) defines an ornamental fence as one with a ratio of solid material to open space of no more than one to four; ornamental fences are exempt from the height limits entirely under Sec. 25-2-899(C). For a solid fence built on the property line, the baseline cap is six feet measured from natural grade under Sec. 25-2-899(D). Two exceptions let a shared boundary fence go higher without a variance.

First, if the grade changes by at least one foot along any run of the fence, that stretch can rise to seven feet under Sec. 25-2-899(E). Second, and this is the real neighbor-consent rule, a fence along the property line can reach eight feet if every owner of property adjoining the section over six feet files written consent with the building official, and either the grade changes by at least two feet within 50 feet of the boundary, or a climbable structure like a telephone junction box exists near the fence that could let a child scale it and reach a hazard such as a pool, under Sec.

25-2-899(F). The consent requirement means a single unwilling adjoining owner can block a neighbor's plan to build past six feet on their shared line. Fences built before July 31, 2023 are grandfathered from the newer design restrictions in Sec. 25-2-899(I), such as the ban on spiked pickets and narrow vertical-picket gaps, unless more than half the fence's linear length gets replaced.
