Buying a high-value commercial property is a major decision. Before any deal closes, it is important to know exactly what you are getting. An ALTA land survey gives buyers, lenders, and developers a detailed look at the property, not just its boundary lines, but everything that could affect its value or use. On expensive properties, that information can make or break a deal.

What Makes an ALTA Survey Different

Most people have heard of a basic boundary survey. It finds the property lines and marks the corners. That works fine for a simple residential lot, but it does not go far enough for a large commercial property.

An ALTA survey follows rules set by two national organizations: the American Land Title Association (ALTA) and the National Society of Professional Surveyors (NSPS). These rules require the surveyor to look at much more than just the edges of the property.

An ALTA survey must show:

• The location of all buildings and other improvements on the property
• Any easements, meaning areas where someone else has the right to use part of the land
• Encroachments, meaning structures from a neighboring property that cross onto the land being surveyed
• Evidence of utility lines running through or near the property
• Rights-of-way that allow others to pass through the land

Because these rules are the same across the country, the survey looks the same whether the property is in Boston, Houston, or Seattle. That makes it easy for lenders and investors to review, no matter where they are based.

Why Lenders Ask for One

Most commercial lenders will not approve a loan on a high-value property without an ALTA survey. This includes SBA loans, large commercial mortgages, and apartment building loans backed by Fannie Mae or Freddie Mac.

The reason is simple. The lender needs to know that the property matches its legal description, that no one else has a hidden claim to part of it, and that there is clear legal access to it. Without an ALTA survey, there is no reliable way to check any of that.

Title insurance companies also require one for commercial properties. Title insurance protects the owner if someone later claims a right to the property. The insurer uses the survey to understand what risks exist before agreeing to provide coverage.

What Can Go Wrong Without One

Skipping an ALTA survey on a high-value property can lead to serious problems down the road. Here are some of the most common issues it catches:

Encroachments. A fence, wall, or building from a neighboring property might be sitting on land that belongs to the buyer. This can cause legal fights and limit what the new owner can do with the property.

Unrecorded easements. Sometimes a utility company or a neighbor has the right to use part of the land, but that right was never officially recorded. A title search alone will not find it. The survey will.

Boundary problems. The written description of a property in old Boston deeds does not always match what is actually on the ground. This is especially common with properties that have long histories. The survey compares both and flags any differences.

Access problems. A property might look like it connects to a public road, but it may not have a legal right to that access. Finding this out before closing is far less costly than finding it out after.

Catching these problems early gives everyone time to work out a solution before the deal is done.

Why Boston Surveys Are More Involved

ALTA surveys in Boston tend to take more time and cost more than in many other cities. There are a few reasons for that.

Boston is one of the oldest cities in the country. Many commercial properties have deed records going back hundreds of years. Digging through those old records takes extra time and can add $100 to $200 per hour to the project cost.

The city is also very dense. Lots are often oddly shaped. Buildings share walls. Underground pipes, wires, and tunnels run in every direction. All of that makes fieldwork more detailed and time-consuming.

Massachusetts also has stricter licensing rules for land surveyors than most states. In addition to national exams, surveyors here must pass a state-specific written test and an oral exam. That extra requirement helps make sure surveyors working in Boston really know the local rules.

A standard ALTA survey costs between $4,329 and $11,544, with a typical turnaround of two to three weeks. Bigger or more complex projects can run higher than $15,000. Boston prices are about 11 percent above the national average.

What Changed in 2026

ALTA and NSPS released updated survey standards that went into effect on February 23, 2026. Any survey ordered on or after that date must follow the new rules.

The biggest change is a new optional item called the Conditions and Potential Encroachments Table. If a buyer or lender requests it, the surveyor must provide a clear summary of any problem conditions found, such as structures crossing boundary lines or sitting inside setback areas. This makes it easier for everyone to spot issues quickly.

The 2026 update also improves how measurement accuracy is reported and how utility conditions are documented. If you are closing a commercial deal right now, make sure your surveyor is using the 2026 standards, not the older 2021 version.

Frequently Asked Questions

Does an ALTA survey replace a title search? 

No. They are two separate steps that work together. The survey shows the physical condition of the property. The title search checks recorded legal documents. You need both to get the full picture.

Are ALTA surveys only for commercial properties? 

Mostly, yes. ALTA surveys are standard for commercial buildings and large apartment complexes. They are not common for single-family homes, though buyers of high-value estates sometimes request one.

When should I order the survey? 

Order it as early as possible, at the very start of the due diligence period. The survey takes two to three weeks under normal conditions. Ordering it late can delay closing, which gets expensive fast on large deals.

What are Table A items? 

Table A is a list of extras that a buyer or lender can add to the base survey. Common choices include flood zone status, zoning setback details, parking space counts, and underground utility mapping. The right choices depend on the property and what the lender requires.
