Texas never adopted one statewide building code, so the fence rule that governs your yard is written by your city and by nobody above it. Houston waves most wood fences through, San Antonio permits nearly all of them, and Dallas and Austin sit at different heights in between. Getting that line right before the crew arrives is cheaper than learning it with the posts already in the ground.
Texas Never Set One Fence Rule, So Your City Did
The state stayed out of this on purpose. Texas has no statewide fence code and no state license for the people who build fences: the state’s occupational-licensing agency regulates about 40 trades, and residential fence builder is not one of them (Texas Department of Licensing and Regulation, 2026). What fills that gap is city code, and the four big metros disagree with each other on height, on material, and on which yard the fence sits in.
So the real question is almost never “do I need a permit.” It is “which line did this fence just cross.” Here is where each metro draws it.
| City | When a residential fence needs a permit | The limit that bites first | Where the rule is written |
|---|---|---|---|
| Houston | Over 8 feet above grade, or masonry or concrete at any height | Material decides it before height does | Houston Permitting Center requirements |
| Dallas | Anything above the by-right height limits | 4 feet in the required front yard, 9 feet in any required yard | Dallas Development Code 51A-4.602 |
| Austin | Over 7 feet, over 6 feet along a public right-of-way, or any height in a floodplain | 6 feet for a solid fence on the property line | Austin Land Development Code 25-2-899 |
| San Antonio | Most new fence construction inside city limits | 3 feet for a solid front-yard fence, 4 feet if predominantly open | San Antonio Unified Development Code 35-514 |
Learn the Terms Your City Code Uses Before You Read It
City fence code turns on four or five words that mean something narrower than they sound. “Above grade” and “from natural grade” are different measurements on a sloped lot. “Required front yard” is a zoning setback, and it is usually deeper than the strip of grass you think of as the front. Read these first and the code reads like a lookup.
| Term | What it means on your lot |
|---|---|
| Above grade | Measured from the ground at the fence line, so a fence on a berm measures taller |
| Required front yard | The zoning setback strip between the street and the front building line, not just the lawn |
| Predominantly open | A fence you can see through, such as wrought iron or chain link |
| 50% open | Dallas’s test for whether a panel is solid enough to need a 5-foot setback |
| Floodplain hazard area | Mapped flood-risk land; in Austin it triggers a permit at any fence height |
Houston Asks What the Fence Is Made Of First
A wood or metal residential fence 8 feet or under needs no building permit in Houston at all, while masonry or concrete construction needs one at any height, including a 3-foot garden wall (City of Houston, 2026). Houston has no zoning, and the fence rule follows that logic: it regulates the risky build, then gets out of the way.
That flips the usual homeowner question. In Houston, the tall wood privacy fence is the easy one and the low brick wall is the paperwork. If a design mixes the two, say a wood fence between stone columns, the masonry portion is what pulls the project into the permit office. We tell the customer that at the estimate, not on install day.
Dallas Regulates Your Front Yard Harder Than Your Back
In every residential district except multifamily, a fence in the required front yard is capped at 4 feet above grade, and no fence in any required yard may exceed 9 feet (Dallas Development Code, 2025). Above those by-right limits, the city requires a building permit. The back yard is rarely the problem in Dallas. The front yard is where plans get redrawn.
There is a second rule out front that catches people. In single-family districts, a fence panel less than 50% open has to sit at least 5 feet back from the front lot line. So a solid 6-foot cedar panel along the street runs into the setback rule before it ever runs into a height rule, and the fix is either a shorter fence, an open one, or 5 feet of yard given back.
Austin Adds a Floodplain Trigger the Other Metros Skip
A fence of any material up to 7 feet is permit-exempt in Austin, as long as the property sits outside a floodplain hazard area; inside one, a fence needs a permit at any height (City of Austin, 2025). Austin also drops the threshold to 6 feet where a residential fence runs along a public right-of-way.
The height itself is measured tighter than most homeowners expect. A solid fence along a property line may not exceed 6 feet from natural grade, and it only earns the seventh foot where there is a grade change of at least 1 foot. On the sloped lots around Round Rock, Cedar Park, and Georgetown, that single sentence decides whether a fence line steps down or gets a permit.
San Antonio Permits Almost Every Fence in the City
San Antonio is the outlier, and it is the strict one. Permits Guide reports that the city requires a permit for most new fence construction inside city limits, filed online through the BuildSA portal for $26.50. Small fee, real step: the default answer in San Antonio is yes, where the default answer in Houston is no.
The height rules are tighter too. A solid front-yard fence is capped at 3 feet and a predominantly open one at 4 feet, an open fence up to 6 feet out front is allowed by right only on lots of at least 20,000 square feet with 100 feet of street frontage, and the maximum residential fence height is 8 feet with no special exception available above it (San Antonio Unified Development Code, 2025). That last clause matters. In San Antonio, 8 feet is a ceiling, and no variance opens it.
But No Permit Does Not Mean No Rules
The code exempts a fence not over 7 feet from a permit and then, in the next breath, still requires the wind load to be worked out per ASCE 7 (2021 International Residential Code and 2021 International Building Code, 2021). Skipping the permit office does not skip the physics, and the physics is what is standing there in the next windstorm.
A solid privacy fence gets treated as a solid freestanding wall, with the design wind force pushing on its whole solid face (ASCE/SEI 7-22, 2022). Around Houston the mapped design wind speeds run on the order of 130 to 140 mph for ordinary structures, rising toward 150 near the shoreline. Three things a permit exemption never covers:
- Post embedment. How deep the posts go and how much concrete surrounds them is set by soil and load, and no city inspection is checking it on an exempt fence.
- End panels and gate posts. Wind pressure runs highest near a wall’s free ends, which is why corners and the tall posts flanking a gate are the first things to lean.
- Deed restrictions. A permit-exempt fence can still violate the covenants recorded on your lot.
Your HOA Still Gets a Say, Inside New Limits
Since September 1, 2025, a property owners’ association may not prohibit an owner from installing a perimeter fence or other security measure, though it keeps limited authority over the fence type and material (Texas Property Code Chapter 202, 2025). Fences installed before that date are grandfathered, and restrictive covenants must be construed liberally toward the owner.
Two association powers survived the change and both shape design. An HOA can still require a driveway gate to sit at least 10 feet back from a laned right-of-way, and it can still bar fencing forward of the front building line. So in a deed-restricted neighborhood, the city code sets your ceiling and the covenants set your style, and both get read before anything gets quoted.
