Why You Need a Fence Survey

What Is a Fence Survey & Why Does It Matter?

A fence survey — also called a property line survey for fence installation — is a boundary survey that marks your exact property lines before a fence goes up. The surveyor researches your deed, locates or sets corner monuments, and flags the boundary so your fence contractor has a clear visual guide for installation.

This is the single most common reason San Antonio homeowners call Alliance Land Surveyors. Fences are expensive — a typical residential fence runs $3,000 to $10,000+ depending on materials, height, and lot size. Building that fence on the wrong side of the property line turns an investment into a liability.

Without a survey, you're relying on assumptions — an old fence line, a neighbor's claim, a rough guess based on where the grass changes. None of these are legally reliable. The only way to know where your property actually ends is a survey conducted by a licensed Registered Professional Land Surveyor (RPLS).

What can go wrong without a fence survey:

Encroachment on neighbor's property — if your fence crosses the property line, your neighbor can demand removal at your expense. In some cases, encroaching fences can even trigger adverse possession claims over time.

Fence built inside an easement — utility companies have the legal right to remove fences built within their easements. You'll bear the cost of removal and replacement, with no reimbursement.

Setback violations — the City of San Antonio has fence height restrictions that vary by setback zone. Front yards, side yards, and corner lots all have different rules. A survey shows where these zones begin and end.

Neighbor disputes — fence-related property line disputes are one of the most common conflicts between San Antonio homeowners. A survey resolves the question with court-reliable evidence before the fence goes up — not after. What to do if your neighbor is building on your land.

A $400 Survey Can Save You Thousands

The cost to remove and reinstall a fence built on the wrong property line is typically $5,000 to $15,000 — plus the legal fees if a neighbor dispute escalates. A fence survey starting at $400 eliminates this risk entirely. It's the cheapest insurance you can buy for your fence project.

Common Scenarios

When San Antonio Homeowners Order Fence Surveys

New Fence Installation

The most common request. You're installing a new wood, iron, chain-link, or vinyl fence and need to know exactly where your property lines are before your contractor starts digging post holes.

Neighbor Disagreement

Your neighbor says the fence is on their property, or you believe theirs is on yours. A survey provides objective, RPLS-sealed evidence that resolves the dispute. Can my neighbor move my stakes?

Replacing an Old Fence

Your existing fence is falling apart, but was it built on the actual property line? Before replacing it in the same location, a survey confirms whether the old fence was in the right spot — or if it needs to move.

New Home Purchase

You just bought a house and want to fence the yard. The title survey from your closing may not show enough detail for fence placement. A dedicated fence survey marks the corners and lines your contractor needs.

Pool or Patio Fencing

Pool fencing in San Antonio must meet specific safety requirements and setback clearances. A fence survey confirms your pool fence placement complies with both property lines and city regulations.

HOA Requirements

Some San Antonio HOAs require a property survey before approving fence installation. The survey confirms the fence plan stays within your property and meets any HOA setback or style requirements.

Our Process

How a Fence Survey Works — Step by Step

Alliance makes the process simple. We coordinate with your timeline so the survey is done before your fence contractor arrives.

1

Request a Quote

Call (210) 369-9509 or fill out the form with your property address and fence installation timeline. We provide an upfront quote the same business day — no surprises.

2

Records Research

Before fieldwork, we research your deed description, recorded subdivision plat, easements, and any prior surveys at the Bexar County Clerk's office. This tells us where the legal boundary should be and what easements may affect your fence placement.

3

Field Survey & Corner Staking

Our crew visits your property with GPS and robotic total station equipment. We locate existing corner monuments or set new iron rods with caps at each property corner. Corners are flagged with witness stakes and ribbon. We can also paint or flag the boundary line between corners so your fence contractor has a continuous visual guide.

4

RPLS Review & Delivery

One of our two Registered Professional Land Surveyors reviews and seals the survey plat. You receive the sealed document via email (PDF) and physical mail. Your property corners are marked on the ground, ready for your fence contractor.

Fence Surveys Often Lead To...

A fence survey frequently uncovers other needs — or homeowners combine the survey with another project to save time and money.

Full Boundary Survey

If you need the complete boundary documented with all corners, dimensions, and a sealed plat — not just the fence line — a full boundary survey is the upgrade. Same crew visit, broader deliverable.

Encroachment Survey

If the fence survey reveals that a neighbor's structure crosses your line (or yours crosses theirs), an encroachment survey provides the detailed documentation needed for resolution or legal action.

Improvement Survey

Planning more than just a fence? An improvement survey documents all structures on the property — house, garage, shed, pool, driveway — relative to the boundaries. One survey covers everything.

Frequently Asked Questions

Fence Survey FAQ — San Antonio

Fence surveys start at $400 plus tax for standard residential lots. Cost depends on lot size, terrain, vegetation, and whether existing corner monuments are recoverable. Call (210) 369-9509 for a free quote.
It's strongly recommended. Building a fence on or over a property line creates legal liability, can require costly removal, and damages neighbor relationships. A fence survey starting at $400 is a fraction of the cost of removing and reinstalling a fence built in the wrong location.
A fence survey is a boundary survey tailored for fence installation. The methodology is identical — deed research, field measurements, corner monuments, sealed plat. The deliverable emphasizes what your fence contractor needs: clearly marked corners and property lines on the ground.
The city doesn't always require a survey for a fence permit, but fences must be built within property lines and comply with height and setback restrictions. A survey is the only reliable way to verify this. If a fence encroaches on a neighbor's property or an easement, the city or the neighbor can require removal at your expense.
Fieldwork for a typical residential lot takes a few hours. Including records research, drafting, and RPLS review, the full process typically takes 3–5 business days. If you have a fence installation date scheduled, let us know and we'll coordinate timing.
We mark property corners with iron rods, caps, and flagged witness stakes. We can also run a string line or paint marks along the boundary to give your fence contractor a continuous visual guide. Your fence should be installed on or slightly inside your property line — never on the neighbor's side.
More common than you'd think. The survey will show exactly where the existing fence sits relative to the legal property line. If it encroaches on a neighbor's property, you'll have documentation to plan the correction. If your neighbor's fence is on your land, the survey gives you evidence to address it. Learn what to do about encroachments.
Texas law doesn't require neighbors to share fence or survey costs. However, many San Antonio homeowners agree informally to split the survey cost when both parties benefit from knowing the property line. The survey is ordered by and delivered to one property owner.
