Why the Lot Plat is the Most Important Document for Your Fence Project
Before you dig a single hole or order a bundle of cedar, you must know exactly where your property ends and your neighbor’s begins. Relying on an old fence line is a common mistake; fences are often built “off-line” to avoid trees or utility boxes.
A Lot Plat (also known as a Land Survey) is a legal document—usually provided in your closing papers—that acts as a bird’s-eye-eye map of your land. Understanding this document is the difference between a successful build and a legal dispute.
1. Identifying the Key Components
When you open your plat, you’ll see a series of lines, numbers, and abbreviations. Here is how to decode them:
- Property Lines (Solid Lines): These represent the legal boundaries of your lot. They are usually labeled with a bearing (direction) and a distance (e.g., N 00° 54′ 30″ E 120.00′).
- Setback Lines (Dashed Lines): Most DFW cities prohibit fences from being built past the “Building Setback Line.” Typically, you cannot build a privacy fence in the area between the front of your house and the street.
- Easements (Labeled P.U.E. or D.E.): * P.U.E. (Public Utility Easement): Areas where utility companies have the right to access underground lines.
- D.E. (Drainage Easement): Areas designed for water runoff. Building a solid fence here can cause flooding and may be illegal.
2. Decoding the Symbols
Surveys use specific symbols to show the “physical” markers found in the ground.
- I.R. (Iron Rod/Pin): This is a metal stake driven into the ground at the corners of your property. If your plat says “Found I.R.,” you can likely find it with a metal detector.
- C.M. (Control Monument): A permanent marker used by surveyors to establish the grid.
- Property Corners: Usually marked with a small circle or a cross-hair on the plat.
3. Understanding Scale and Orientation
- The North Arrow: Always check the compass rose on the plat. Your backyard might not be “South” just because it feels that way; the plat provides the true orientation.
- The Scale: Most residential plats are drawn at a scale of 1″ = 20′ or 1″ = 30′. You can use a standard ruler to estimate the distance from your house to the property line.
4. Fencing Near Easements: The “Removable” Rule
In many North Texas cities like Murphy and Wylie, if your property line falls within a Utility Easement, you may still be allowed to build a fence, but with conditions:
- Access: The utility company has the right to tear the fence down to access their lines.
- Style: You may be required to use Ornamental Iron or a gate with a removable section so they can get equipment through without a bulldozer.

5. Pro-Tip: Find the “Pins” Before You Build
The lines on the paper are the legal truth, but the Iron Rods (Pins) in the ground are the physical proof.
- Use your plat to locate the corners of your lot.
- Use a metal detector or a small shovel to find the iron rod buried 2–4 inches underground.
- Once you find the pins, run a string line between them. This is your “Legal Path” for the fence.
Ready to Plan Your Layout?
Once you’ve identified your boundaries and setbacks on your plat, you’re ready to calculate your materials. Using a plat ensures you don’t over-order (or under-order) your pickets and rails.
