Texas Property Survey: What Buyers and Sellers Need to Know

By Cindy Dunnican | June 28, 2026

Most buyers don't think much about the survey until it shows up on their closing disclosure. Then they see a line item for $450–$600 and wonder what they're actually paying for — or whether the seller was supposed to handle it.

If you're buying or selling in Rockwall, Rowlett, or anywhere in the DFW area, here's what you need to know before you hit that moment.

The Survey Explained

A property survey is a map of the land — and more. It shows:

• The legal boundaries of the lot and their exact dimensions
• The location of every structure relative to those boundaries (your home, garage, driveway, fence, pool, shed)
• Easements — the portions of your property that utility companies, the city, or other parties have the right to use or access
• Encroachments — when a neighbor's fence, driveway, or outbuilding crosses onto your lot, or when yours crosses onto theirs
• Setback violations — structures built closer to the property line than local zoning allows
• Flood zone classification

That last point — flood zone — matters more than many buyers expect near Lake Ray Hubbard. Properties in flood-adjacent areas of Rowlett and Rockwall can sit close enough to a FEMA-designated zone that a current survey is the only reliable way to confirm where the boundaries fall.

What's the practical takeaway? The survey is the document that tells you what you actually own and what you can actually do with it.

Existing Survey vs. New Survey — and Why It Matters

Texas doesn't require sellers to provide a current survey at closing. But most lenders do require one to approve the loan, and title companies need one to issue a full title policy without what's called a "standard survey exception."

The standard survey exception means the title policy excludes anything a current survey would have revealed — boundary disputes, encroachments, easement issues, and setback problems. If you close without a current survey, your title policy has that exception built in. If you provide a current survey, you can often get that exception removed or narrowed, which meaningfully expands your coverage.

Here's how the survey decision plays out in Paragraph 6 of the TREC contract:

If the seller has an existing survey: The seller can provide it, along with a T-47 affidavit (more on that below). If the title company and lender accept it, no new survey is needed. This is the most common scenario in established neighborhoods across Rockwall County.

If the seller doesn't have an existing survey — or if the lender or title company rejects it: A new survey has to be ordered. Paragraph 6 specifies who pays. This is negotiable, and in today's buyer-leaning market, buyers in Rowlett and Rockwall are increasingly negotiating for the seller to cover this cost.

New survey cost in DFW: Standard residential surveys typically run $400–$700, with larger lots or irregularly shaped properties running higher. Budget one to three weeks for completion, which is why it needs to be ordered early in your option period if it's required.

The T-47 Affidavit: What It Is and Why Sellers Get Tripped Up

The T-47 is a Texas Department of Insurance-promulgated document. When a seller provides an existing survey, they're required to sign and notarize a T-47 affidavit swearing that the condition of the property has not materially changed since that survey was completed.

Think of it this way: the survey was drawn at a specific point in time. The T-47 is the seller's sworn statement that nothing significant has happened since — no new fence, no addition, no pool, no outbuilding.

The T-47 must be delivered to the buyer at the same time as the survey, typically within three to five days of the effective contract date. This is a seller obligation, and one that gets missed more often than it should.

If the seller misses the T-47 delivery deadline, the contract typically shifts the cost of a new survey to the seller — even if the contract originally assigned it to the buyer. It's the kind of detail that causes frustration mid-transaction when everyone's attention is focused on bigger things.

If you're a seller in Rockwall or Rowlett with an existing survey, pull it out early and ask your agent about the T-47 process before you're under contract. It's a simple step that tends to create unnecessary friction when it's left until the last minute.

What Can Go Wrong — and What Buyers Should Watch For

Survey problems are more common than most buyers expect, especially in established neighborhoods where fences have been up for decades and clay soil has been doing what North Texas clay soil does: shifting.

The most common issues that surface on surveys in our market:

Encroachments: A neighbor's fence crosses your property line by six inches. Your detached garage sits two feet onto their lot. These things happen — often without either party knowing — and they show up clearly on a current survey. Some encroachments are minor and can be resolved with a boundary line agreement. Others are significant enough to affect the deal.

Easement issues: Utility easements, drainage easements, and access easements run through a lot of properties in Rockwall County, including newer ones. An easement doesn't necessarily kill a deal, but it does limit what you can build on that portion of the lot. If you're planning to add a pool, extend a driveway, or build a structure in the backyard, the survey needs to come back clean in that location first.

Setback violations: Structures built too close to property lines — sometimes by previous owners, sometimes without permits — show up as setback violations on a survey. These can affect future financing and resale.

The timing of when these issues surface matters enormously. Most surveys are ordered in the first week of the option period. If a problem appears, you still have time to negotiate a resolution, request a price adjustment, or walk away. If you didn't order a survey and a problem shows up after closing, you're dealing with it on your own — and without the expanded title coverage a current survey provides.

If you're buying a home that's 20 or more years old in Rowlett or Rockwall, order the survey early. Clay soil moves structures over time, and fences tend to drift in the direction of whoever planted them. This connects directly to foundation issues we cover in detail in our post on foundation issues in North Texas — what buyers and sellers need to know.

A Note for New Construction Buyers in Fate, Royse City, and Lavon

If you're buying new construction in the eastern growth areas of Rockwall County's orbit — Fate, Royse City, Lavon — the builder will typically provide a survey at closing. But there's a distinction worth understanding.

A plat map shows how the land was divided into lots. A property survey shows what's actually built on your specific lot and where everything sits relative to the boundaries. They're related documents, but they're not the same thing.

Ask your builder whether the survey they're providing is a current as-built survey of your specific lot — not just a copy of the plat or a generic lot survey done before construction began. You want the one that was completed after your home was finished and reflects exactly where the structure sits.

Also worth knowing: new construction lots in MUD and PID districts often have additional easements for utility infrastructure, drainage, and district access. Your survey is the document that shows exactly where those easements run on your lot.

For Sellers: What to Do Before You List

If you're preparing to sell in Rockwall County or Rowlett, locate your existing survey now — before you're under contract and on a timeline. It's typically in the closing documents from when you purchased the home.

Once you have it, ask your agent to review it with you:

• Does it show any improvements that were added after the survey date (pool, addition, new structure)?
• Is it likely to be accepted by the buyer's lender and title company, or will a new survey be needed?
• What's your T-47 obligation and when is it due?

Sellers who go into a transaction knowing their survey situation avoid a common source of last-minute friction. And if you're pricing your home in this market, having your paperwork organized signals to buyers that the transaction is going to be clean — which matters in a market where buyers have options.
