Does Texas law require a survey before building a fence?

No Texas statute requires a survey before building a fence. However, local municipalities often require a survey or site plan as part of the fence permit application. More importantly, the Texas Agriculture Code's Good Neighbor Fence law, which can require a neighbor to share costs, only applies when you can establish where the shared property line sits. A survey provides that proof.

What is the Texas Good Neighbor Fence law?

Texas Agriculture Code Section 74.101 allows a property owner to require an adjacent landowner to pay half the cost of a fence on a shared boundary. To invoke this right, you must give written notice to the neighbor and allow a reasonable time for them to build their half or agree to cost sharing. Without a survey establishing the shared boundary, cost-sharing disputes become harder to resolve.

What happens if I build a fence over the property line in Texas?

In Texas, building a fence on a neighbor's property creates legal liability. The neighbor can demand removal at your expense. Texas courts take encroachments seriously, and a fence placed even a foot over the line can result in a trespass claim. You pay to move the fence, restore any disturbed property, and potentially cover the neighbor's legal costs if they have to sue.

How much does a boundary survey cost for a fence project in Texas?

Boundary surveys in Texas typically cost $400 to $900 for a standard residential lot. Rural acreage surveys run higher, often $800 to $2,000 or more depending on acreage and terrain. Get quotes from at least two licensed Texas RPLSs to compare pricing.

Do I Need a Survey to Build a Fence in Texas?

Q: Does Texas have an open range or closed range law that affects fences?

Yes. Texas has both open range and closed range counties. In open range counties, livestock owners are generally not required to fence livestock in. In closed range counties, they are. Whether your county is open or closed range affects your obligations if livestock crosses onto your property. Check with your county commissioner's court or the Texas and Southwestern Cattle Raisers Association for your county's designation.

Key takeaway

Texas has a Good Neighbor Fence law that can make your neighbor pay half. But cost-sharing and dispute resolution both require knowing where the line is.

The Short Answer

Texas law does not require a survey before you build a fence. But Texas has a specific fence cost-sharing law that can require your neighbor to pay half, and that law only works cleanly when the property line is clearly established. A survey gives you the documentation to back up your boundary claim, whether you are invoking the cost-sharing law or just trying to avoid putting the fence in the wrong place.

Texas Fence Law: What You Actually Need to Know

The Good Neighbor Fence Law

Texas Agriculture Code Section 74.101 is the foundation of Texas fence law between adjacent property owners. Under this law, an adjacent landowner can be required to share the cost of a fence along a common boundary. The process works as follows:

You give written notice to your neighbor stating that you intend to build a fence and requesting them to build their proportionate share, or to pay you half the cost of a fence you build.
The neighbor has a reasonable time to respond and either build their portion or enter a cost-sharing agreement.
If they refuse or do not respond, you can build the fence and pursue them in court for half the cost.

This law applies to rural agricultural land in most of its original application, but Texas courts have applied related principles to urban boundary fences as well. The key practical point: you cannot successfully invoke this law if you and your neighbor dispute where the boundary sits. A survey removes that dispute.

Open Range vs. Closed Range Counties

Texas has a historical distinction between open range and closed range counties. In open range areas, livestock owners are not required to fence animals in, and neighboring landowners who do not want livestock on their property are responsible for fencing them out. In closed range areas, livestock owners must contain their animals.

Most suburban and urban Texas counties are effectively closed range due to local ordinances. But if you are in a rural or semi-rural area, understanding whether your county is open or closed range affects your legal obligations and your neighbor's obligations when it comes to fence building and maintenance.

Local Permit Requirements

In Texas cities and suburban counties, fence permit requirements vary widely. Most cities require a permit for fences over four feet tall. Many require a site plan or survey showing fence placement. Check with your local city or county building department before starting. Examples:

The City of Austin requires a permit for most fences and asks applicants to demonstrate compliance with setback requirements, which requires knowing where the property line sits.
Houston requires a permit for fences over four feet and has specific rules about fences in easements.
Dallas requires permits for most residential fences and specifies setback and height requirements by zoning district.

Why Building Without a Survey Is a Real Risk in Texas

Property lines in Texas are often less obvious than property owners assume. In older neighborhoods, lot corners may have been disturbed, buried, or lost entirely. In rural areas, the original survey may be decades or even a century old, with corner monuments that are difficult to locate without professional equipment.

The risks of building without a survey:

Encroachment claims: If your fence crosses onto a neighbor's property, they can demand removal at your expense. Texas courts consistently enforce property rights, and there is no grace period for accidental encroachments.
Cost-sharing disputes: If you invoke Section 74.101 and the neighbor challenges the boundary location, you will need a survey to prove your case anyway. Getting one after a dispute starts is more expensive and stressful than getting one before.
Easement conflicts: Many Texas properties have utility, drainage, or pipeline easements. A fence built in an easement can be required to be removed by the easement holder at any time, at your cost.
HOA violations: Many Texas subdivisions have deed restrictions and HOA rules about fence placement. Violations can result in fines and required removal.

When a Survey Is Effectively Required in Texas

Even without a state mandate, a survey becomes a practical requirement in these common fence scenarios:

Your neighbor disputes where the line sits and you want to invoke cost-sharing under Section 74.101
Your city's permit application asks for certified boundary information or a site plan showing setback distances
There are no visible corner markers on your property
Adjacent properties have fences that do not align with where you believe the line to be
Your property is rural and the legal description is in metes and bounds from an old abstract

How a Boundary Survey Works in Texas

Texas licensed surveyors hold the title of Registered Professional Land Surveyor (RPLS). The process for a residential boundary survey for a fence project is straightforward:

You contact a licensed Texas RPLS and provide the property address and county appraisal district parcel number.
The surveyor researches the county appraisal district records, the county clerk's deed records, and the original field notes from the Texas General Land Office if applicable.
A field crew visits to locate or set corner monuments and measure the boundary.
A survey drawing is produced showing the property corners, dimensions, easements, and any encroachments found.
Corner markers, typically iron rods or pins, are set or confirmed in the field for you to reference when placing the fence.

Typical Survey Costs for a Texas Fence Project

Standard residential lot in a city or suburb: $400 to $900
Semi-rural lot, 1 to 5 acres: $700 to $1,500
Rural acreage, 5 to 50 acres: $1,200 to $3,000
Large rural tracts or properties with complex histories: $2,500 or more

Costs in Texas can vary significantly by region. Urban areas with dense records and easy lot access tend to cost less than rural areas with older surveys or difficult terrain.

What to Do Before Calling a Surveyor in Texas

Find your property's parcel ID on your county appraisal district website (search for "[county] appraisal district").
Check your original purchase closing documents for an existing survey. If it is recent and corner markers are still in place, it may be usable.
Look up whether your county has any open/closed range designations if you are in a rural area.
Check your local city or county building department's website for fence permit requirements before scheduling the survey, so you know what format the permit office needs.

Find a licensed Texas RPLS in your area through the directory. Search by city or county, compare listings, and get quotes from multiple surveyors before your fence project starts.
