If you are buying a commercial property or working with a lender on a real estate deal, you have probably heard the term ALTA survey. Most people have no idea what it means. 

What Is an ALTA Survey?

An ALTA survey is the most detailed property survey you can get in the United States. It maps out a property’s boundaries, buildings, easements, and anything else that could affect who owns what and how the land can be used.

The name comes from the American Land Title Association, or ALTA. This group worked with the National Society of Professional Surveyors (NSPS) to create a single set of rules that all licensed surveyors must follow when completing this type of survey. Those rules are called the Minimum Standard Detail Requirements.

Because every surveyor follows the same rules, a lender in Texas will accept an ALTA survey from Florida without question. That consistency is exactly why banks, title companies, and attorneys trust this survey above all others.

The current rules took effect on February 23, 2021. A new update went into effect on February 23, 2026. ALTA and NSPS update their standards every five years to keep up with changes in the industry.

What Does an ALTA Survey Include?

Every ALTA survey must show the following:

• The property’s boundary lines and corners
• The location of all buildings and structures on the land
• All easements and rights-of-way listed in the title commitment
• Any encroachments from or onto neighboring properties
• All access points to and from public roads
• The legal description of the property
• A signed and sealed certification from a licensed surveyor

What Are Table A Items?

Clients and lenders can also request extra details called Table A items. These are optional add-ons that go beyond the basics. Common examples include:

• Flood zone classification
• Location of above-ground utilities
• Zoning classification and setback requirements
• Topographic data and site elevations
• Parking layout and counts
• Square footage of buildings and total land area

Your lender or title company will tell you which Table A items they need. Each one added to the survey increases the level of detail and the final cost.

When Do You Need an ALTA Survey?

Buying or refinancing commercial property. Almost every commercial real estate transaction in the United States requires an ALTA survey. Lenders need it to confirm the property lines, check the legal description, and spot any problems before the deal closes.

Your lender or title company asks for one. If they require it, there is no way around it. A basic boundary survey will not meet their standards.

The property has a complicated history. If there are old easements, boundary disputes, or unclear descriptions in the records, an ALTA survey clears things up before they become your problem after closing.

You are developing or investing in property. Developers buying land for new construction use an ALTA survey as the foundation for site planning, engineering, and zoning applications. Investors buying apartment buildings, office spaces, or shopping centers also rely on them to map out shared spaces, parking areas, and tenant boundaries.

ALTA Survey vs. Boundary Survey

A boundary survey marks property lines. It works fine for most homes. An ALTA survey does everything a boundary survey does, plus much more. It is the only type of survey that lenders and title companies accept for commercial transactions.

Feature	Boundary Survey	ALTA Survey
Follows national standards	No	Yes
Documents easements	Sometimes	Always
Notes encroachments	Sometimes	Always
Maps utilities	No	Optional
Accepted by lenders	Rarely	Yes
Typical cost	$500 – $2,000	$2,500 – $15,000+

How Much Does an ALTA Survey Cost?

Property Type	Typical Cost
Small urban parcel (under 1 acre)	$1,000 – $3,500
Suburban commercial lot (1 – 5 acres)	$2,500 – $6,000
Larger parcel (5 – 25 acres)	$5,000 – $12,000
Rural or complex site (25+ acres)	$10,000 – $30,000+

A few things that affect the final price:

• Property size and shape. Larger and more irregular parcels take more time to survey.
• Number of Table A items. Each optional item adds to the scope and the cost.
• Available records. If old surveys and title documents are easy to find, the surveyor spends less time on research.
• Rush delivery. If you need the survey in five to seven business days instead of the standard two to four weeks, expect to pay 25 to 50 percent more.

Getting quotes from more than one licensed surveyor can lower your cost by 15 to 30 percent. Sharing any existing survey records or title documents with your surveyor upfront also helps cut down on research time.

Why ALTA Surveys Matter for Title Insurance

When you buy title insurance, the policy usually includes something called a survey exception. This means the insurance does not cover any boundary problems or encroachments that a survey would have found. In other words, if there is a problem with the property lines and no survey was done, you are on your own.

When a title company receives an acceptable ALTA survey, it can remove that exception. That means your policy covers more, and both you and your lender are better protected.

This is the main reason lenders require an ALTA survey for commercial deals. They want a title policy with no gaps in coverage.

Frequently Asked Questions

Do I need an ALTA survey for a regular home purchase? 

Usually not. Most home loans only require a standard boundary survey or mortgage location survey. The exception is if the home is a high-value property, a multi-unit building, or has a complicated title history.

Can I use an old ALTA survey? 

Sometimes. Most lenders and title companies want a survey that is no more than six months to one year old at the time of closing. If the property has changed since the last survey was done, it will need to be updated.

Who is allowed to prepare an ALTA survey? 

Only a licensed land surveyor who holds an active license in the state where the property is located. The finished survey must include the surveyor’s signature, seal, and the date it was certified. Always choose a surveyor with experience in ALTA surveys specifically, not just general boundary work.
