If you are buying or financing a commercial property, your lender or title company will likely ask for an ALTA survey before closing. For many people, this is the first time they have heard the term. Here is what it means and why it matters.

What Is an ALTA Survey?

An ALTA survey is a detailed land survey that follows national standards set by two organizations: the American Land Title Association (ALTA) and the National Society of Professional Surveyors (NSPS). Together, they define exactly what information the survey must include, how it must be formatted, and what level of accuracy is required.

The full name is the ALTA/NSPS Land Title Survey. It is widely considered the most thorough type of land survey available, and it is specifically designed for commercial real estate transactions.

Because every ALTA survey follows the same national standards, lenders, title companies, attorneys, and buyers across the country can all read and rely on the same document. That consistency is one of the biggest reasons lenders require it.

How Is an ALTA Survey Different From a Boundary Survey?

A boundary survey establishes the legal property lines of a parcel. It is the standard survey used for most residential properties and straightforward land transactions.

An ALTA survey does everything a boundary survey does, and then goes much further. It also documents:

• All improvements on the property, such as buildings, parking lots, and fences
• Easements and rights-of-way that affect the land
• Encroachments, where a structure crosses a property line
• Access points and roads serving the property
• Utilities and underground features, when requested
• Zoning classification and flood zone status, when included

The ALTA survey is built for complex, high-value transactions where a basic boundary survey would leave too many questions unanswered.

Why Do Lenders Require an ALTA Survey?

When a lender finances a commercial property, they need confidence that the property is exactly what the documents say it is. An ALTA survey gives them that confidence by verifying that:

• The property boundaries match the legal description in the deed
• There are no encroachments that could affect the value or use of the property
• All easements and access rights are properly documented
• There are no hidden title issues that could create legal problems later

Title insurance companies also rely on ALTA surveys to remove the standard “survey exception” from a title policy. Without a current ALTA survey, the title policy may exclude coverage for survey-related issues, which leaves the lender and the buyer exposed.

The lender, the title insurer, and the buyer all benefit from having a single standardized document that lays out the full picture of the property.

What Are Table A Items?

One of the unique features of an ALTA survey is a menu of optional additions called Table A items. The current 2026 ALTA/NSPS standards include 20 optional Table A items that can be added to the base survey.

Common Table A items include:

• Flood zone classification based on current FEMA maps
• Zoning information, including setback requirements and permitted uses
• Utility locations, including above-ground and underground lines
• Topographic data, showing land elevations and contours
• Parking counts, which matter for certain commercial uses
• Wetlands identification, when relevant to the site

The lender or title company typically specifies which Table A items they require based on the type of property and the loan program. Most commercial transactions require at least several Table A items. Selecting them in advance keeps costs predictable and avoids delays later in the process.

How Much Does an ALTA Survey Cost?

An ALTA survey costs more than a standard boundary survey because it covers more ground and requires more research. According to current 2026 pricing data, most ALTA surveys for standard commercial parcels fall between $3,000 and $8,000. Larger or more complex properties can cost $15,000 or more.

The main factors that affect the cost include:

• Property size and shape. Larger parcels and irregularly shaped lots take longer to survey.
• Number of Table A items. Each optional item adds to the scope and the cost. Table A additions typically add between $500 and $2,000 to the base price.
• Site complexity. Properties with multiple buildings, limited prior records, or difficult terrain require more work.
• Location. Urban areas with established surveying firms are generally 10 to 30 percent lower in cost than rural areas with fewer practitioners.
• Timeline. Rush orders can significantly increase the price. Starting the process six to eight weeks before closing is recommended to avoid rush fees.

How Long Does an ALTA Survey Take?

Most ALTA surveys take two to three weeks to complete from the time the surveyor is hired. The process includes title research, fieldwork, drafting, and review.

Properties with complex histories, limited records, or multiple improvements may take longer. If you are working toward a specific closing date, communicate that timeline to your surveyor early so they can plan accordingly.

When Do You Need an ALTA Survey?

An ALTA survey is most commonly required in the following situations:

Purchasing commercial property. Lenders and title companies almost always require an ALTA survey before a commercial real estate closing.

Refinancing a commercial property. If you are refinancing, your lender may require a new or updated ALTA survey, especially if significant time has passed or improvements have been made since the last one.

Purchasing vacant commercial land. Even without existing buildings, lenders financing raw commercial land often require an ALTA survey to document boundaries, access, easements, and any encumbrances.

Development projects. Developers frequently order ALTA surveys early in the due diligence process to understand site constraints before committing to a project.

Frequently Asked Questions

Is an ALTA survey required for residential properties? 

Not typically. ALTA surveys are designed for commercial transactions. Most residential closings use a standard boundary survey instead.

Who orders and pays for an ALTA survey? 

In most transactions, the buyer orders and pays for the ALTA survey as part of their due diligence. The cost is sometimes negotiated between parties.

Can an old ALTA survey be used for a new transaction? 

It depends on the lender. Many require a fresh survey, especially if the prior one is several years old or was completed under older standards. The current ALTA/NSPS standards took effect on February 23, 2026.

What happens if an ALTA survey reveals a problem? 

The parties have the opportunity to address it before closing. Catching an encroachment, easement conflict, or boundary issue during due diligence is far less costly than discovering it after the transaction is complete.
