City of Austin Fence Code: Heights, Permits, and Penalties

The Austin fence code exempts most residential fences from permitting: if your fence is seven feet tall or shorter and your lot is not in a flood hazard area, you do not need a building permit.¹ That covers most standard privacy fences. But the exemption only removes the permit step. Height limits, material restrictions, placement rules, sight-triangle requirements at corners, and pool safety standards all still apply, and getting any of them wrong can lead to fines up to $2,000 per day and an order to tear the fence down.

When a Permit Is Required

A permit is not needed for the typical six-foot backyard fence on a standard lot. It is required in three specific situations:

The fence is taller than six feet along a City of Austin right-of-way other than an alley. This also requires a letter of authorization, which in turn requires a Board of Adjustment variance.²
The fence is located inside a flood hazard area. Height and material do not matter; any fence in a floodplain needs a permit.²
The fence exceeds eight feet. Fences over eight feet always require a permit and a Board of Adjustment variance.

If your project falls into any of these categories, file through the Austin Build + Connect (AB+C) portal.³

How Tall Your Fence Can Be

The baseline for a solid fence on a property line is six feet, measured from the natural grade.² Mounding soil or piling landscaping under the fence to gain height doesn’t work; the measurement starts at existing ground level.

Seven feet is allowed for any section of a property-line fence where there’s a grade change of at least one foot along that section.² This handles sloped lots without forcing an awkward gap at the low end.

Eight feet is allowed in two situations without any neighbor consent: a solid fence sitting on or inside the building setback lines (in other words, pulled in from the property boundary), and a fence along a property line that borders commercial or industrial zoning, or that is separated from such zoning only by an alley.²

You can also build a property-line fence up to eight feet with the adjoining owner’s written consent, but only if one of two conditions is met: a grade change of at least two feet within 50 feet of the shared boundary, or a nearby structure that could let a child climb over a six-foot fence and reach a hazard such as a pool.² Get the neighbor’s written agreement before you build. After the fence is up, a complaint can turn what looked like a friendly understanding into an enforcement action.

Materials That Are Not Allowed

Barbed wire and razor wire are prohibited on residential fences in Austin. Electric fences are also restricted in residential areas.² Wood, masonry, ornamental metal, and chain link are all fine.

Corner Lots and Sight Triangles

Corner lots carry a rule that catches people off guard. Before building, you’re expected to contact Austin Transportation and Public Works to confirm the fence won’t block traffic visibility.² The view-obstruction rules in City Code Section 14-9-2 and the Transportation Criteria Manual establish sight triangles at intersections where a fence has to stay low enough or open enough for drivers to see cross-traffic and pedestrians.

Reach Transportation and Public Works by calling 3-1-1, through the mobile app, or online.² A fence that clears every height limit on the lot will still be ordered removed if it obscures a driver’s line of sight.

Pools, Floodplains, and Historic Districts

Three situations put your fence under rules beyond the general code.

If the fence serves as a pool barrier, Chapter 25-12, Article 14 of Austin’s city code (the Swimming Pool and Spa Code) and Texas Health and Safety Code Chapter 757 control.² Those rules set stricter minimum heights, require self-closing and self-latching gates that open away from the pool, and specify latch heights designed to keep young children from opening them. Treat the pool code as the controlling standard for any fence enclosing a pool.

Inside a flood hazard area, every fence needs a permit regardless of height or material.² A solid fence in a floodplain can act as a dam during heavy rain, pushing water onto neighbors or public infrastructure. Austin’s FloodPro tool will tell you whether your property is in a mapped floodplain before you plan the project.

In a locally designated historic district, 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 That can constrain your choice of material, style, and height beyond what the general code requires. Check with Development Services before committing to a design.

Applying for a Permit

When a permit is required, filing happens through the AB+C portal.³ You’ll need a site plan showing where the fence will sit relative to property lines and existing structures, along with the height and materials. If you don’t have a current survey, get one first. Building over a property line, even by inches, is one of the fastest routes to a lawsuit and a removal order.

Permit fees vary by project scope; the current fiscal year 2025–2026 schedule is on the Development Services website. Once the fence is built, the city inspects it to confirm it matches the approved plans.

Who Pays and Which Side Faces Out

Texas has no statute requiring your neighbor to split the cost of building or maintaining a shared fence. Without a written agreement, neither party has a legal obligation to contribute to the other’s fence.⁴ Homeowners moving from states with cost-sharing statutes are often surprised by this.

Austin’s code also does not require you to orient the finished side of the fence toward your neighbor or toward the street. Both questions are worth settling in writing before construction. Once the fence is up, you lose whatever leverage you had to negotiate.

What Happens If You Don’t Follow the Rules

Enforcement starts with a Notice of Violation. The notice itself is not a fine or a citation; it’s a demand to fix the problem within a set window.⁵ If you don’t resolve the violation, the city can escalate through Administrative Hearings, the Building and Standards Commission, or Municipal Court. Fines can reach $2,000 per violation per day in Municipal Court or $1,000 per violation per day in an Administrative Hearing, plus additional fees.

The fines are not the whole picture. A non-compliant fence can be ordered removed at your expense, complicate a title when you try to sell, and expose you to liability if someone is hurt by a structure that violated the safety code.
