Not all land surveys are the same. If you are thinking about buying property, building something new, or developing land, you might need a land survey. But which type is right for your situation?
There are six main types of land surveys available, and choosing the right one depends on what you are trying to accomplish. Understanding the differences between them will help you make the best decision for your property needs.
Quick Decision Guide
Before diving into the details, here is a simple way to figure out which survey you need.
Are you buying residential property? You need a boundary survey to see exactly where the property lines are.
Are you getting a commercial mortgage or closing on commercial property? Your lender will require an ALTA survey.
Are you building, developing, or planning construction? You need a topographic survey to understand the slopes and features of your land.
Do you need elevation data for flood insurance or construction purposes? An elevation certificate shows the exact height of your building relative to flood levels.
Do you want fast, detailed mapping for large properties or complex terrain? Drone and LiDAR mapping provides aerial views and precise measurements without traditional ground surveys.
Are you starting construction and need to verify boundaries and grades? A construction survey ensures your building is placed correctly on the property.
Boundary Survey: The Most Common Type
A boundary survey shows exactly where your property lines are. It marks the corners of your land and shows what is yours and what belongs to neighbors. This is the most common survey because many situations require it.
You need a boundary survey when buying property, making improvements, or dealing with neighbor disputes. When a surveyor does a boundary survey, they use old records and field measurements to find exact property corners, marking them with stakes or flags. The survey shows your structures and boundary lines to give you a clear picture of what you own.
ALTA Survey: The Detailed Professional Option
ALTA stands for American Land Title Association. An ALTA survey is much more detailed than a boundary survey. It includes everything in a boundary survey but adds information that title companies and lenders need.
ALTA surveys are required for most commercial real estate deals and mortgages. An ALTA survey shows property lines, easements, utilities, and building setbacks. It includes detailed review of public records. Because ALTA surveys are more comprehensive, they provide the complete information needed for commercial transactions and mortgages.
Topographic Survey: For Development and Construction
A topographic survey focuses on the shape and features of land. It shows elevation changes, slopes, hills, valleys, drainage patterns, vegetation, and natural features.
You need a topographic survey if you are planning to build or develop land. Architects and engineers use these surveys to understand the terrain. Utah has many properties with significant elevation changes near mountains and the Wasatch Front, making topographic surveys essential for construction planning. Developers use them when planning subdivisions or commercial projects to determine lot layout and road placement.
Elevation Certificate: For Flood Insurance and Building
An elevation certificate shows the exact height of your building relative to the flood level for your area. This is important if your property is in or near a flood zone.
Flood insurance companies require elevation certificates to determine insurance rates. Lenders also require them before approving mortgages in flood-prone areas. An elevation certificate includes measurements of your building and surrounding ground, showing whether your property is in a flood zone and the level of flood risk.
Drone and LiDAR Mapping: Fast and Accurate
Drone and LiDAR mapping uses aerial technology to create detailed maps of property. LiDAR stands for Light Detection and Ranging and uses laser pulses to measure distances and create precise three-dimensional maps.
This technology is faster than traditional surveys for large properties or difficult terrain. It works well for properties with mountains, forests, or rough ground and can map hundreds of acres quickly. Drone and LiDAR mapping is popular with developers, engineers, and construction companies in Utah because it handles complex terrain easily and provides detailed elevation data across entire properties.
Construction Survey: During Building
A construction survey helps ensure your building is placed correctly on the property. It marks where the building should go, shows property lines, and verifies that you are building within setback requirements.
Construction surveys happen at the start of building and sometimes during construction to check progress. They ensure the building is the right distance from property lines and follows local zoning rules. They also verify that utilities are not being damaged during construction.
If you are building a house, commercial building, or development project, a construction survey is essential to prevent costly mistakes.
Comparing Your Options
Here is how to think about each survey type:
Boundary surveys answer, “What land do I own?” They are best for residential purchases and property disputes.
ALTA surveys answer, “What are all the legal and physical issues affecting this property?” They are best for commercial deals and mortgages.
Topographic surveys answer, “How is the land shaped, and what features does it have?” They are best for development and construction planning.
Elevation certificates answer, “How high is my building above the flood level?” They are best for flood insurance and mortgages in flood zones.
Drone and LiDAR surveys answer, “What does my entire property look like from above?” They are best for large properties, complex terrain, and fast mapping.
Construction surveys answer, “Am I building in the right place?” They are best during the building process to ensure accuracy.
Finding the Right Survey for Your Situation
Understanding these six types of surveys helps you figure out what you actually need. The wrong choice wastes money and time. The right choice protects your investment and prevents future problems.
Think about what you are trying to do with your property. That answer will usually point you toward the right survey type. Whether you need a simple boundary survey or a complex combination of services, the right survey gives you the information you need to move forward with confidence.
