Fence height and permit rules in Austin

When a fence needs a permit

City of Austin Development Services’ Fencing Regulations say a fence needs a permit if it’s in a floodplain, more than 7 feet high at any point, or more than 6 feet high on residential property along a City public right-of-way other than a public alley. A fence that doesn’t need a permit still has to follow the City’s fence rules. The City’s list of work exempt from building permits includes fences no more than 7 feet high that aren’t in a flood hazard area.

The Fencing Regulations page also says a fence over 6 feet along the right-of-way needs a City letter of authorization, which requires a Board of Adjustment variance. Where the grade changes at least one foot along the property line, a fence up to 7 feet needs no variance.

How tall a fence can be

Austin City Code § 25-2-899 (Municode version of August 26, 2026) limits a solid fence along a property line to 6 feet, measured up from the natural grade. Where the grade changes at least one foot along a run, that part may reach 7 feet. A fence up to 8 feet on a property line needs each adjoining owner’s written consent filed with the building official, plus either a grade change of at least two feet within 50 feet of the boundary or a structure, such as a telephone junction box, that could let a child climb a 6-foot fence into a hazard like a swimming pool.

The same section allows a solid fence up to 8 feet on or within the building setback lines. It also allows that height between a residential use and commercial or industrial property.

Solid or ornamental

The City of Austin Fencing Regulations page defines a solid fence as having more than 20% solid material and says a chain link fence is generally considered ornamental. Austin City Code § 25-2-899 defines an ornamental fence as an open design with no more than one part solid material to four parts open space, and its height restrictions don’t apply to that fence. The permit triggers on the City’s page still apply to ornamental fences.

Corner lots

City of Austin Fencing Regulations say a solid fence on a corner lot needs approval from Austin Transportation and Public Works so it won’t block drivers’ views of traffic. The same page points to City Code § 14-9-2 and the City’s Transportation Criteria Manual for the guidelines on view obstruction.

Safe-fencing rules since 2023

Austin City Code § 25-2-899 says fences built after July 31, 2023 may not have spiked pickets, spiked bars, or other spiked decorative elements above the top horizontal rail. It also bars vertical pickets above the top rail separated by more than two inches and less than nine inches, razor-like wire, and barbed wire unless the fence encloses an airport and federal aviation rules require it. Under the same section, a solid chain link fence must use knuckle selvage, with the twisted wire ends along the edge bent back into knuckles.

The same section says that when more than 50 percent of an existing fence’s length is replaced, the whole fence must comply. Fences built before July 31, 2023 are exempt. City of Austin Fencing Regulations say the City adopted these rules on July 20, 2023 to reduce features that make fences more dangerous for children and wildlife.

Floodplains, trees, meters, and pools

City of Austin Fencing Regulations say a fence in a floodplain needs a permit at any height. The same page says trees 19 inches or more in diameter on the property may mean a tree review, and fences must not block utility meters or wastewater cleanouts. It also says fences over 6 feet in the wildland-urban interface, where homes meet undeveloped wildland, may need review or permits.

Austin City Code § 25-2-899 says a fence used as a swimming pool barrier must comply with the City’s Swimming Pool and Spa Code (Chapter 25-12, Article 14). The City’s pool code sets the barrier details.

HOAs and fences

Texas Property Code § 202.023, as amended by S.B. 711 effective September 1, 2025, says a property owners’ association may not adopt or enforce a restrictive covenant that prevents an owner from installing security measures, including a perimeter fence. The same section still lets an HOA regulate the type of fencing, bar fencing in a drainage easement or drainage area, require a driveway gate to sit at least 10 feet back from the right-of-way where the driveway meets a laned roadway, and, if a covenant provides for it, bar fencing in front of the house’s front-most building line.

The same section says perimeter fencing or front fencing built before September 1, 2025 may stay. It doesn’t apply to condominiums.

Calling 811 before digging

Texas Utilities Code § 251.151 says anyone who intends to excavate must notify a notification center no earlier than 14 days and no later than 48 hours before digging begins, not counting Saturdays, Sundays, and legal holidays. Under § 251.002 of the same code, excavating includes digging with an auger, the powered drill used to dig post holes, and other powered or mechanized digging that disturbs soil 16 inches or deeper.

Texas811’s homeowner page lists building or repairing a fence as a project that needs the call. The same page says that when you hire a contractor, it’s the contractor’s responsibility to contact 811 two business days before digging.

Outside the City of Austin

The permit, height, corner-lot, safe-fencing, and pool rules here are the City of Austin’s, while the HOA and 811 laws apply statewide in Texas. Round Rock, Cedar Park, Georgetown, Pflugerville, Leander, Kyle, Buda, San Marcos, and the other towns, along with unincorporated county land, set their own fence rules. HOA deed restrictions add rules of their own, so check with your city and your HOA.
