AUSTIN FENCE PLANNING GUIDE
FLOOD ZONES, WILDFIRE ZONES, SOIL, AND UTILITIES TO CHECK FIRST
Before you build a fence in Austin, there are a few things worth checking: whether your property is in a floodplain, whether it’s in a wildfire zone, what’s in the ground, where your utilities and easements are, and what your HOA allows. Skipping these can lead to code enforcement issues, disputes with neighbors, or tearing out a fence and starting over. We’re Paragon Fence, an Austin fence contractor, and we’ve seen all of that firsthand. This page collects the free resources we use ourselves, so you can set your project up for long-term success.
HOW DO I CHECK IF MY AUSTIN PROPERTY IS IN A FLOODPLAIN?
If your property is in a flood zone, your outdoor project is likely going to require a permit from the city first. Fences in or near a floodplain can have extra rules, and cities often mandate specifics about how and where the fence is built. In some instances, structural engineers can be required.
Use FloodPro, the City of Austin’s public floodplain map, and search your address.
If you're outside Austin city limits, you can confirm with FEMA’s Flood Map.
Austin’s maps can be more detailed than FEMA’s, so check both if you're an Austin homeowner.
IS MY AUSTIN HOME IN A WILDFIRE ZONE (WUI)?
The Wildland-Urban Interface (WUI) map shows where development meets natural vegetation and wildfire risk is higher.
The City’s 2025 update placed just over half of Austin’s habitable land in a risk zone. Search your address with the WUI interactive map.
Depending on your zone, material choice matters, and noncombustible options like steel are worth considering.
We’ve seen too many other companies around Austin using non-compliant materials. At Paragon, we can help you make an informed choice.
WHAT SOIL AND ROCK ARE UNDER MY TEXAS YARD?
The USGS Texas geology map gives a general view of what’s under your property, from clay to limestone to sandy soil.
This affects how deep fence posts need to go and how difficult the digging will be. Around Austin, we usually see a soft layer clay followed by limestone deeper down. So, if you see someone setting your fence posts 12” deep, chances are that sucker’s gonna be leaning in no time, even if it’s set in concrete.
The geology map is a general guide, it’s not a replacement for using our eyes. We’ll make sure we consider your unique soil conditions when setting posts.

DO I NEED TO CALL 811 BEFORE INSTALLING A FENCE IN TEXAS?
Texas law requires you or your contractor to contact 811 at least two business days before digging, even in your own backyard.
As your fence contractor, we handle this for you. But if you plan to do any future digging, Texas 811 is free, and it protects you from hitting gas, electric, water, or communication lines.
It does NOT mark private utility lines. If you know of any, please let your fence contractor know. Not only could it be an inconvenience to you, but it can be a safety risk for our crews.
WHAT ABOUT EASEMENTS, PROPERTY LINES, AND HOA RULES?
We will usually ask you for a copy of your survey when we first hear from you.
This allows us to review for utility and drainage easements, and confirm where your property line actually is.
Some easements allow limited improvements depending on their terms, so read your records before building.
If you’re unsure of the boundary, a survey costs far less than moving a fence.
If you’re in an HOA, check their fence rules first. Unfortunately, HOA’s don’t share with non-residents, so we rely on homeowners to review those guidelines.
We are happy to pull together project plans that you can submit to your HOA for approval.
This city of Austin also has a HOA registry search.
Many contractors are focused on a quick sale. We’d rather you avoid code enforcement, legal disputes, and costly rebuilds. We’ll keep adding resources to this page as we find tools that help our fellow Austinites make informed decisions.
This page is general information, not legal advice. Confirm requirements with the City of Austin, your utility providers, or your HOA.
