What Is a Property Survey?
A property survey is a professional measurement and mapping of a parcel of land that defines its legal boundaries, identifies improvements, and documents easements, encroachments, and other features. In San Antonio, property surveys are prepared and sealed by a Registered Professional Land Surveyor (RPLS) licensed by the Texas Board of Professional Engineers and Land Surveyors.
Think of a property survey — sometimes called a property line survey — as the definitive map of what you own. It shows the exact dimensions of your lot, the location of your house, garage, fences, driveways, and any other permanent structures. It also reveals easements — areas where utility companies, the city, or neighbors may have legal rights to access — and encroachments, where improvements cross a property line.
In Bexar County, property surveys are relied upon by title companies, lenders, real estate attorneys, and the City of San Antonio permitting office. A sealed survey from a licensed RPLS is the standard of evidence for establishing property boundaries in Texas courts.
A property survey in San Antonio typically includes:
Boundary lines — the legal limits of your property, established from deed descriptions, recorded plats, and field measurements. Your survey crew will locate and verify (or set new) iron rods, concrete monuments, or other markers at each corner.
Improvements — the location of your house, garage, sheds, fences, driveways, patios, pools, and other permanent structures relative to the property lines and setback requirements.
Easements and rights-of-way — areas where utility companies, drainage districts, or other parties have recorded rights. These affect what you can build and where.
Encroachments — if your neighbor's fence is on your land or your driveway extends beyond your boundary, the survey documents it.
Flood zone information — for properties near creeks, rivers, or FEMA-designated flood areas, the survey can show your property's relationship to flood boundaries. If you need formal flood documentation, ask about our elevation certificates.
When Do You Need a Property Survey in San Antonio?
A property survey isn't just a formality — it protects your investment, prevents legal disputes, and ensures your project starts on solid footing. Here are the most common reasons San Antonio property owners order a survey.
Buying or Selling a Home
Most San Antonio title companies and lenders require a current survey before issuing title insurance. A title survey confirms the property matches its legal description and reveals any issues that could delay closing.
Building a Fence
Don't guess where your property line is. A fence survey marks your exact boundaries so your contractor builds on your land — not your neighbor's. This is one of the most common reasons homeowners call us.
New Construction or Additions
The City of San Antonio requires surveys for building permits on new construction and major additions. Our construction staking services ensure your builder starts in the right place.
Neighbor Boundary Disputes
If your neighbor's structure, tree, or fence appears to be on your property, a boundary survey provides the legal documentation to resolve the dispute — in conversation or in court.
Refinancing Your Mortgage
Lenders often require a current mortgage survey during the refinance process. If your existing survey is outdated or shows changes have been made, a new one is typically needed.
Subdividing or Platting Land
Dividing a larger tract into smaller lots for sale or development requires a platting survey that meets Bexar County and City of San Antonio subdivision requirements.
How Much Does a Property Survey Cost in San Antonio?
At Alliance Land Surveyors, residential property surveys start at $400 plus tax for standard lots. Final cost depends on property size, terrain, documentation requirements, and survey type. Here's a general breakdown.
| Survey Scenario | Typical Range | Key Factors |
|---|---|---|
| Standard residential lot (< 1/4 acre) | $400 – $600 | Subdivision plat on file, accessible corners, no complications |
| Larger residential lot (1/4 – 1 acre) | $500 – $900 | Additional boundary length, possible terrain challenges |
| Acreage tracts (1 – 10+ acres) | $800 – $2,500+ | Extensive fieldwork, difficult terrain, deed research complexity |
| ALTA/NSPS survey (commercial) | $1,500 – $5,000+ | Table A items, title commitment review, zoning research |
| Topographic survey | $800 – $3,000+ | Site size, density of features, elevation data requirements |
Why the range? Every property is different. Factors that influence cost include lot size, how easy it is to locate recorded monuments, vegetation and terrain on-site, the age and quality of prior surveys on record, and whether the survey requires ALTA standards or additional certifications.

How a Property Survey Works — Step by Step
Alliance Land Surveyors follows a proven 5-step process to deliver accurate, RPLS-sealed property surveys. Here's what to expect when you hire us.
Request a Quote
Contact us with your property address, a copy of your deed (if available), and a description of what you need — fence line marking, closing requirement, boundary dispute, etc. We'll provide a clear, upfront quote typically within the same business day.
Records Research
Before we ever set foot on your property, our team researches the chain of title at the Bexar County Clerk's office. We pull deed descriptions, subdivision plats, recorded easements, and any prior surveys. This research phase is critical — it establishes the legal framework for your boundary and identifies potential complications before fieldwork begins.
Field Survey
A licensed survey crew visits your property with GPS receivers and robotic total stations. They measure boundaries, locate all improvements (house, fences, driveways, pools, etc.), recover existing property corner monuments, and set new markers where needed. For most residential lots in San Antonio, fieldwork takes a few hours.
Drafting & Quality Review
Field data is imported into professional CAD software where our drafters produce the survey plat. One of Alliance's two Registered Professional Land Surveyors reviews the plat for accuracy, verifies calculations, and confirms compliance with Texas Board standards before sealing the document.
Delivery & Support
You receive the sealed survey plat via email (PDF) and physical mail. Our team is available to walk you through the findings, answer questions from your title company or lender, and provide additional certified copies as needed. We keep your survey on file for future reference.
