City of Austin Fence Code: Heights, Permits, and Pool Barriers

Austin’s fence code lets you build a residential fence up to seven feet tall without a permit, as long as the property is not in a flood hazard area.¹ That exemption covers most standard privacy fences. The catch is that the city’s height, material, and placement rules still apply whether or not you pull a permit, and getting them wrong can mean fines, forced removal, or a stalled sale when you try to transfer the property.

When a Permit Is Required

Three situations pull a residential fence out of the exempt category and into permit territory:

The fence is taller than six feet along a City of Austin public right-of-way other than an alley. These fences need a permit plus a letter of authorization, and the letter itself requires a Board of Adjustment variance.²
The fence sits inside a flood hazard area. Any fence in a floodplain requires a permit regardless of height or material.²
The fence is taller than eight feet. These always require a permit and a Board of Adjustment variance.

When a permit is required, applications go through the Austin Build + Connect portal, which handles submission, fees, and inspection scheduling.³

How Tall Your Fence Can Be

The baseline is six feet. A solid fence along a property line can go up to six feet, measured from the natural grade.² You cannot mound soil or build up landscaping to gain extra height; the measurement starts at existing ground level.

Seven Feet on Sloped Lots

If any section of a solid property-line fence has a grade change of at least one foot, that section can go up to seven feet.² The allowance exists so sloped lots don’t end up with awkward gaps at the bottom of a rigid six-foot run.

Eight Feet in the Interior or Next to Commercial Zoning

A solid fence located on or within the building setback lines, meaning the interior of your lot away from the property boundary, can be up to eight feet tall. A fence along a property line adjacent to commercial or industrial zoning, or separated from such zoning only by an alley, can also reach eight feet.²

Eight Feet With a Neighbor’s Written Consent

A property-line fence can also reach eight feet with written consent from the adjoining owner, but only if one of two conditions exists: a grade change of at least two feet within 50 feet of the shared boundary, or a structure on the property that could let a child climb over a six-foot fence and reach a hazard like a swimming pool.² Get the agreement in writing before building. Doing it after a complaint has already been filed is much harder.

Materials You Cannot Use

Austin bans barbed wire and razor wire on residential fences. Electric fences are also restricted in residential areas.² Standard materials like wood, masonry, ornamental metal, and chain link are all acceptable.

Corner Lots and Sight Lines

Corner lots carry an extra requirement. Before building, contact Austin Transportation and Public Works to confirm the fence will not obstruct traffic visibility.² The city’s view-obstruction rules, in City Code Section 14-9-2 and the Transportation Criteria Manual, create sight triangles at intersections where a fence has to stay low enough or transparent enough for drivers to see oncoming traffic and pedestrians.

Transportation and Public Works can be reached by dialing 3-1-1, through the mobile app, or online.² A fence that blocks a driver’s line of sight will draw a removal order even if it meets every height limit elsewhere on the lot.

Fences in a Floodplain

A fence anywhere inside a floodplain requires a permit, no matter how short it is or what it’s made of.² The seven-foot exemption does not apply. A solid fence can act as a dam during heavy rain and push floodwater onto neighboring properties, which is why the city treats floodplain fencing as a separate category.

Pool Barrier Fences

If the fence also functions as a pool safety barrier, standard residential fence rules are only the starting point. Pool barriers have to comply with Chapter 25-12, Article 14 of the city code (the Swimming Pool and Spa Code) and the state Health and Safety Code Chapter 757.² Those provisions impose stricter requirements, including minimum barrier heights, self-closing and self-latching gates that open away from the pool, and specific latch-height thresholds. If you’re installing a new pool or replacing an existing pool fence, treat the pool code as controlling and confirm your design with Development Services.

Historic District Properties

Properties inside a locally designated historic district face additional design constraints. Fences must meet safe fencing standards first, then conform to the applicable historic design standards to the greatest extent possible while still meeting safety goals.² In practice this can limit material, style, and height choices beyond what the general code requires. Contact Development Services before committing to a design.

Shared Fences and Your Neighbor

Texas has no state law requiring your neighbor to split the cost of building or maintaining a fence on a shared property line. Without a written agreement, neither party has a legal obligation to contribute to the other’s fence expenses.⁴ Homeowners moving to Austin from states with cost-sharing statutes often assume the rule carries over. It does not.

Austin’s code also does not require you to orient the finished side of the fence toward your neighbor or the street. A written agreement covering cost, style, and orientation before construction is the best way to keep a neighbor dispute from turning into a code complaint or a boundary lawsuit. The leverage to negotiate disappears once the fence is up.

Penalties for a Non-Compliant Fence

Code enforcement begins with a Notice of Violation, which is not itself a fine.⁵ The notice gives you a window to correct the problem. If the violation isn’t resolved in time, the city can escalate, and penalties can reach up to $2,000 per violation per day in Municipal Court or up to $1,000 per violation per day in an Administrative Hearing, plus additional fees.

The non-financial consequences matter too. A non-compliant fence can trigger mandatory removal at your expense, create title complications at sale, and expose you to liability if someone is injured by a structure that violates safety code.

Variances for Anything Outside the Rules

Projects that fall outside the standard limits need a Board of Adjustment variance. The most common trigger is a residential fence taller than six feet along a public right-of-way other than an alley, which requires a variance and a letter of authorization before a permit can issue.² Variances are discretionary; the Board weighs whether your situation justifies an exception. Schedule an appointment with Development Services to confirm the requirement and the timeline before you commit to a design that depends on one.
