You’re about to close on a commercial property. The deal looks clean. Then your title company asks for an ALTA survey. You say yes without fully knowing what it means. That’s a problem. An ALTA survey is one of the most detailed land surveys you can order on a property. It follows a strict national standard set by the American Land Title Association (ALTA) and the National Society of Professional Surveyors (NSPS). If you’re a developer, this report can protect you from very expensive surprises.

What an ALTA Survey Actually Covers

A standard boundary survey tells you where a property starts and ends. An ALTA survey goes further. Much further.

It gives you a full picture of everything that could affect how you use the land. That includes easements, encroachments, rights-of-way, utilities, access points, and more.

The Components That Matter

The survey follows a checklist called “Table A.” Some items are required. Others are optional but often requested by lenders or title companies. Common items include:

• Property boundaries and corners
• Easements and rights-of-way visible on the ground
• Improvements on the property (buildings, parking lots, fences)
• Utilities and underground lines
• Flood zone classifications
• Access to public roads
• Zoning classification confirmation
• Evidence of cemeteries, bodies of water, or wetlands

Each item checked means more data. More data means fewer surprises after you close.

How It Differs from a Boundary Survey

A boundary survey maps the edges of a property. That’s it. An ALTA survey maps the edges AND everything on, under, and near the property that could affect ownership or use.

Think of it this way: a boundary survey tells you where the fence should go. An ALTA survey tells you whether someone else has the legal right to walk through that fence line every morning.

Who Needs an ALTA Survey?

Not every property transaction needs one. But if you’re in commercial real estate, the answer is usually: you do.

Developers and Investors

If you’re buying land to build on, you need to know exactly what you’re dealing with before you pull permits. Encroachments, utility conflicts, or an undisclosed easement can kill a project plan fast.

An ALTA survey shows you those problems before construction starts. That’s the point.

It’s also required by most lenders for commercial loans. If your deal involves financing, expect to order one.

Lenders and Title Companies

Title insurers often require an ALTA survey before they’ll issue a title policy on a commercial property. Without it, they can’t confirm that the title is clear of physical conflicts.

Your lender wants proof too. They’re putting money into the same deal you are. They want to know the property is exactly what it looks like on paper.

When Is an ALTA Survey Required?

There’s no single law that says “you must get an ALTA survey.” But practically speaking, you’ll need one in these situations:

• Commercial real estate purchases above a certain value (threshold varies by lender)
• Any deal where a lender requires title insurance
• Properties with complex easements or shared access
• Multi-tenant or multi-parcel properties
• Ground lease transactions
• Refinancing a commercial property

If you’re doing a small residential purchase, you probably won’t need one. If you’re buying a shopping center or an office complex, plan on it.

What the Report Shows You

The final ALTA survey is a detailed map. It shows the boundary lines, all improvements on the property, and every easement or encumbrance that was found.

Surveyors also write a certification statement. That statement confirms the survey meets ALTA/NSPS standards. Title companies and lenders rely on that certification.

Here’s what developers tend to care about most:

• Easements: Does someone else have the right to use part of your land? A utility company, a neighbor, a municipality?
• Encroachments: Is a building or fence crossing the property line?
• Access: Can you legally reach a public road from this property?
• Flood zone status: Is any part of the property in a FEMA-designated flood zone?

Missing any of these before closing is a costly mistake.

How Long Does It Take and What Does It Cost?

Turnaround time varies. A typical ALTA survey takes two to four weeks. Complex properties with lots of recorded easements or large acreage can take longer.

Cost also varies. For a small commercial lot, you might pay $2,000 to $4,000. Larger or more complex properties can run significantly higher. The scope of Table A items selected also affects the price.

Get quotes early. Don’t wait until you’re close to closing to order the survey. Delays here can push your entire timeline back.
