When you’re buying a home in Texas — whether it’s a new construction home in San Antonio or a resale property with decades of history — one of the most important documents you’ll encounter is the survey. A survey outlines the exact boundaries of the property, the location of improvements, and any encroachments or easements that may affect how you can use the land.
Surveys are essential for protecting your investment, yet many buyers don’t fully understand what they include, why they matter, or when they’re required. In Texas, surveys play a major role in title insurance, lender requirements, and even your ability to build or make improvements in the future.
This guide breaks down everything you need to know about surveys in real estate — what they are, what they show, how much they cost, and how they protect you during the homebuying process.
What Is a Survey in Real Estate?
A survey is a detailed map created by a licensed surveyor that shows the exact boundaries, measurements, and physical features of a property.
In simple terms:
A survey tells you exactly what land you’re buying — and what’s on it.
A survey typically includes:
• Property boundaries
• Lot dimensions
• Fence lines
• Easements
• Setbacks
• Improvements (house, driveway, patio, pool, etc.)
• Encroachments
• Right of way access
• Utility locations
Surveys are essential for confirming that the property matches what’s being sold.
Why Surveys Matter in Texas Real Estate
Texas has a wide variety of property types — from suburban lots to rural acreage — and surveys help ensure you’re buying exactly what you think you’re buying.
Surveys protect you from:
• Boundary disputes
• Encroachments from neighbors
• Illegal additions
• Building in restricted areas
• Violating HOA or city setback rules
• Title insurance exceptions
• Future legal issues
Without a survey, you may inherit problems that are expensive and time consuming to fix.
What Does a Survey Show?
A standard Texas survey includes several key components.
1. Property Boundaries
The survey outlines the exact perimeter of the property using:
• Measurements
• Bearings
• Coordinates
This ensures you know the true size and shape of the lot.
2. Improvements
The survey shows the location of:
• The home
• Garage
• Driveway
• Sidewalks
• Patios
• Decks
• Pools
• Sheds
This helps confirm that all improvements are within the property boundaries.
3. Easements
Easements give others the right to use part of your property.
Common easements include:
• Utility easements
• Drainage easements
• Access easements
• HOA easements
Easements can limit where you can build or make improvements.
4. Setbacks
Setbacks are required distances between structures and property lines.
Examples:
• Front yard setback
• Side yard setback
• Rear yard setback
These rules affect additions, pools, and exterior changes.
5. Encroachments
Encroachments occur when:
• A neighbor’s structure crosses onto your property
• Your structure crosses onto a neighbor’s property
• A fence is built in the wrong place
Encroachments can lead to legal disputes if not addressed.
6. Right of Way Access
Surveys confirm legal access to the property, especially important for rural land.
7. Flood Zones
Some surveys include FEMA flood zone information, which affects insurance requirements.
Who Pays for the Survey in Texas?
In Texas, the survey cost is negotiable.
Typically:
• The buyer pays for the survey
• The seller may provide an existing survey to save costs
• The title company must approve any existing survey
If the seller provides an existing survey, they must also provide a T 47 affidavit, confirming no changes have been made to the property.
What Is a T 47 Affidavit?
A T 47 affidavit is a sworn statement from the seller confirming:
• The existing survey is accurate
• No structural changes have been made
• No new improvements affect the boundaries
If the seller cannot provide a valid T 47, the buyer must purchase a new survey.
How Much Does a Survey Cost in Texas?
Survey costs vary based on:
• Lot size
• Property type
• Complexity
• Location
Typical costs:
• $400–$600 for standard residential lots
• $600–$1,200 for larger or irregular lots
• $1,000–$3,000+ for acreage or rural land
New construction surveys may cost more due to additional steps.
When Is a Survey Required?
A survey may be required when:
• The buyer is financing the home
• The title company needs survey coverage
• There is no existing survey
• The existing survey is outdated or inaccurate
• There are boundary or encroachment concerns
Cash buyers may choose to skip the survey — but this is risky.
How Surveys Affect Title Insurance
Title insurance companies use surveys to determine:
• Whether the property has encroachments
• Whether easements affect the home
• Whether improvements violate setbacks
• Whether survey coverage can be issued
Survey Coverage
Survey coverage protects buyers from:
• Boundary disputes
• Encroachments
• Survey errors
Without a survey, the title company will exclude these items from coverage.
Common Survey Issues in Texas
Texas homes — especially older properties — may have survey issues such as:
1. Fence Encroachments
Fences often do not match property lines.
2. Driveway or Patio Encroachments
Improvements may cross into easements or neighboring lots.
3. Setback Violations
Additions or sheds may violate city or HOA rules.
4. Utility Easements
These may limit where you can build a pool or patio.
5. Shared Driveways
These require clear legal access.
6. Missing or Incorrect Legal Descriptions
Older properties may have outdated descriptions.
Surveys in New Construction
New construction surveys are typically completed in phases:
• Lot survey
• Form survey (foundation layout)
• Final survey
These ensure the home is built within boundaries and meets setback requirements.
Builders usually provide a final survey at closing — but buyers should still review it carefully.
Surveys in Rural Properties and Acreage
Rural land requires more detailed surveys due to:
• Larger boundaries
• Easements
• Access roads
• Fences
• Water features
• Mineral rights
These surveys are more expensive and take longer to complete.
Should You Ever Skip a Survey?
Skipping a survey is risky.
You should never skip a survey if:
• The property has no existing survey
• The lot is irregular
• There are fences or improvements near boundaries
• You plan to build or add structures
• The property is older
• The property is rural
A survey is a small cost compared to the potential legal issues it prevents.
Final Thoughts: A Survey Protects Your Property Rights
