Platting vs. Surveying: What’s the Difference and When Do You Need Each in Texas?

If you’re buying land, developing property, or planning to subdivide acreage in Texas, you’ll likely come across the terms platting and surveying. While these services are closely related, they serve different purposes—and knowing when you need each can save you time, money, and legal trouble.

This blog breaks down the difference between platting and surveying, how they work together, and when each is required for real estate and development projects in Texas.

What Is a Land Survey?

A land survey is a professional assessment that measures and maps the physical boundaries of a property. It defines where your land begins and ends, identifies improvements and encroachments, and provides crucial legal and zoning information.

Common Types of Surveys:

• Boundary Survey – Confirms property lines and corners

• Topographic Survey – Shows elevation and land features

• ALTA/NSPS Survey – For commercial real estate and title insurance

• Construction Survey – Lays out building footprints and site elements

Surveys are often required by title companies, lenders, and city permitting offices, especially before real estate closings or construction.

What Is Platting?

Platting is the legal process of dividing a tract of land into lots, blocks, and streets—often for development or resale. A plat is a recorded map that becomes part of the public record and shows how the land is intended to be used.

In Texas, platting must follow strict local regulations and be approved by the city or county where the land is located.

Types of Plats:

• Preliminary Plat – The first step in showing how land will be divided

• Final Plat – The official document filed with the county

• Replat – Used when modifying an existing plat

• Amending Plat – For minor corrections or changes to a previous plat

Platting is typically required when creating new lots, developing a subdivision, or combining parcels.

How Surveys and Plats Work Together

A survey provides the measurements and data used to create or update a plat. If you’re subdividing property, your surveyor will:

• Measure and map the land

• Identify easements, flood zones, and setbacks

• Design lot lines and access roads

• Prepare a plat that meets local development codes

Once complete, the plat is submitted for approval by the appropriate city or county planning department.

When Is a Survey Required in Texas?

You’ll likely need a survey when:

• Buying or selling real estate

• Applying for permits

• Installing fences, driveways, or structures

• Confirming boundary lines or easements

• Submitting for platting or replatting

When Is Platting Required in Texas?

Texas law typically requires platting when:

• You’re dividing a tract into two or more parts for sale or development

• You’re changing property lines or lot sizes

• You’re combining multiple parcels into one

• You’re developing commercial or residential subdivisions

Even if you own the full tract, local governments may not allow construction or utility service without a recorded plat.

Why This Matters for Property Owners and Developers

Understanding the distinction between platting and surveying can help you:

• Avoid project delays and denied permits

• Navigate city and county regulations

• Reduce legal and title issues during closing

• Improve land value and marketability

Attempting to bypass the platting process or relying on outdated surveys can result in hefty fines, project shutdowns, or failed sales.
