Whether you're installing a white-picket fence or buying a new property, land surveys will become your best friend. There are many types of land surveys to consider—from mortgage to topographic options—but what is a land survey exactly? Here's what to know, including the cost of a land survey, the reasons to get one, and whether you need to call a local land survey team.

What Is Land Surveying?

A land survey is a detailed, aerial view drawing or diagram that clearly shows your property lines complete with measurements. It also describes the land features and other structures on the property.

Depending on your budget and the requirements for the project, you can pay a property surveyor for more detailed renderings that include photographs, previous property changes or improvements, the presence of utilities, and any location-specific issues like a floodplain or sinkhole. 

The extent of the land rendering will depend on the type of land survey you choose.

 6 reasons to get a land survey, including selling property or building an addition

When Would You Get a Land Survey?

You need a land survey to prevent future problems, or at least to let you know of potential issues. Land surveys reveal current and future issues associated with the property.

Here are five reasons residential land surveys are crucial for buyers. 

1. Land Surveys Tell You Where You Can (and Can’t) Build

When building a new addition (garage, driveway, home, deck, patio), you’ll need to make sure you’re building on your own land or risk the financial loss of a teardown and rebuild.

2. You Need a Land Survey for an Accurate Fence Line

If a fence lies between you and your neighbor’s house, you may want to figure out who owns a shared fence. If it falls on their property, they are responsible for all maintenance, and if it falls directly on the property line, you share those costs with your neighbor. You will need an accurate survey for your fence line, or it could cost more in the long run. The same is true for tree and shrub lines.

Angi Tip

The last thing you want is to end up in a boundary dispute with your neighbor. Having a land survey readily available can prevent the need for legal proceedings and preserve your relationship.

3. Land Surveys Alert You if a Neighbor Has Built on Your Land

Your neighbor might have any of the above built on your potential property or may try to build in the future. Having a residential survey done protects you from these potential issues. 

4. You’ll Have More Peace of Mind With a Residential Land Survey

Property surveys also offer peace of mind as you plan for future projects, like a fence, home addition, or a deck. No homeowner wants to find out they’ve built on their neighbor’s land and they’d like it removed now, please.

5. Land Surveys Are Crucial for When You Sell Your Property

Hiring a land surveyor is also a good idea if you’re considering dividing and selling your land in the future. They’ll know local laws that will affect your plans. They might even help you go through the process of seeking approval during city or county meetings.

Can You Survey Land Yourself?

In most states, you cannot submit a DIY survey as an official document, such as mortgage paperwork or before new construction. However, you can perform a survey for your own curiosity–or to confirm your property lines–before you build a fence or move a tree, for example. Keep in mind that this will require you to read a land plot and do a good deal of measuring. If there are legal debates on the line, it is always best to contact a local surveyor

How Much Does a Land Survey Cost?

The average cost of a land survey is $500, which is a bargain compared to what you could pay to fix property line errors in the future. Of course, the total depends on the property's history, size, location, and unique features. Keep in mind that you will also pay an average of $1,600 for the cost of a building permit once you have the project approved by the surveyor.

Ask your surveyor if they provide a free estimate for the property. But for reference, a historic farmhouse on a large property unfamiliar to the surveyor costs much more than a new construction home in a new subdivision with easily accessible records.

Also, note that a paid residential land survey could be part of your overall property buying negotiations, but it isn’t required to seal the deal.

Frequently Asked Questions

Land surveys are worth it in several scenarios including selling your home, building an addition, constructing a fence, or making major changes to your landscape. A professional land survey can help you avoid legal issues with your neighbors and confirm the value of your property. In many cases, you may be required to order a land survey to receive a construction permit or mortgage loan.

Depending on the type of land survey, the report will mark the boundaries of your property, the topographical changes of the landscape, as well as major natural and added structures to the plot. A more detailed survey, like an as-built survey, will note the measurements of the structures and landscape following major construction. A topographic survey will also help your contractor determine the cost of land development projects.

You will find a collection of licensed land surveyors in your area. Your real estate agent or construction manager may also be able to recommend a trusted professional. When speaking with prospective pros in your area, ask the land surveyor if they are licensed in the state, have liability insurance, and can quote you a fee before starting.
