You found the property. The numbers work. You’re ready to close.

Then your lender asks for an ALTA land survey. And until you get one, nothing moves.

This isn’t bureaucratic red tape. Lenders and title companies require ALTA surveys because they’re carrying real financial risk the moment a commercial deal closes. They need to know exactly what they’re lending against. An ALTA survey is how they find out.

This article explains why that requirement exists, what it protects and what happens when a deal runs into problems.

What Makes an ALTA Survey Different From a Standard Survey

Most surveys confirm where the property lines sit. An ALTA survey goes further.

It follows a strict set of national standards published jointly by the American Land Title Association and the National Society of Professional Surveyors, last updated in 2021. Those standards require the surveyor to locate and map:

• Property boundaries
• Easements and rights-of-way
• Encroachments from neighboring properties
• Above and below-ground utilities
• Setback lines and zoning restrictions
• Access to public roads
• Bodies of water and flood zone boundaries

A standard boundary survey won’t catch all of this. An ALTA survey is built specifically to satisfy lenders and title insurers.

Why Lenders Require an ALTA Survey

The Property Is the Collateral

When a lender funds a commercial real estate deal, the property backs the loan. If a borrower defaults, the lender needs to know they can recover their money.

An ALTA survey tells them what they’re actually holding. An easement can limit how the property gets used. A structure from a neighboring lot sitting on the land cuts its value. A recorded access restriction that nobody mentioned during negotiations changes the whole picture.

These issues affect what the property is worth. A lender can’t approve a loan without knowing about them.

Loan Size and Transaction Type Trigger the Requirement

For most residential deals, a basic survey is enough. Commercial loans work differently. Most institutional lenders require an ALTA survey for any commercial transaction, regardless of size. Some apply a dollar threshold, typically around $500,000, but many require it across the board.

If the financing comes through a bank, credit union or a commercial mortgage-backed securities (CMBS) program, an ALTA survey is standard. Fannie Mae and Freddie Mac guidelines for commercial transactions both list it as a required document during loan origination.

It Protects the Lender’s Own Title Insurance Policy

Lenders don’t rely on the buyer’s title policy. They require a separate lender’s title insurance policy that covers their interest in the property independently.

A title insurer won’t issue that policy without reviewing an ALTA survey first. The survey tells them what exceptions to list, what risks exist and whether the policy can even be written without major carve-outs.

Why Title Companies Require It

Title Insurance Has Blind Spots Without Survey Data

A title company’s job is to insure the ownership history of a property. They search public records for liens, judgments and ownership disputes. But public records don’t show everything.

They won’t show a fence sitting six inches over the property line. They won’t show a drainage easement that was never recorded correctly. They won’t show an access road that a neighboring owner has been using for years without any formal agreement.

An ALTA survey fills those blind spots. Without one, a title company issues a policy loaded with broad survey exceptions.

Survey Exceptions Stop Deals

Lenders won’t accept a title policy with open-ended survey exceptions. If the title commitment comes back with language stating the company takes no responsibility for matters a physical inspection would have revealed, your lender will pause the deal until that language is resolved.

The only fix is an ALTA survey. Once the title company reviews it, they can either insure over the issues found or list specific exceptions based on what the surveyor actually mapped. Broad exceptions are a red flag. Specific ones, tied to real data, are manageable.

What Happens When Problems Show Up

An ALTA survey sometimes uncovers issues that change the deal. That’s the entire point.

Common findings on commercial properties include encroachments where a structure crosses a property line, utility easements that shrink the buildable footprint, access easements that give third parties legal rights to cross the land and flood zone boundaries that affect insurance costs and what can be built.

Finding these before closing gives you options. You can renegotiate the price, require the seller to fix the defect or exit the deal with your deposit. Finding them after closing means those problems are yours to solve.

How Long It Takes and What It Costs

An ALTA survey on a commercial property in South Florida typically takes two to four weeks from the start of fieldwork. Sites with multiple parcels or dense utility infrastructure take longer.

Cost depends on lot size, site conditions and which optional Table A items the lender or title company requires. Most commercial ALTA surveys range from $2,500 to $8,000. Larger or more complex sites run higher.

Order it early. Survey delays are one of the most common reasons commercial closings get pushed back.

Frequently Asked Questions

Why do lenders require an ALTA survey instead of a regular boundary survey? 

Lenders require ALTA surveys because they follow national standards built specifically for commercial lending and title insurance. A regular boundary survey confirms property lines. An ALTA survey maps easements, encroachments, utilities and other conditions that affect the property’s value as loan collateral.

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

Sometimes. Most lenders and title companies accept an ALTA survey no older than six months, provided the surveyor re-certifies it and no material changes have occurred on the property. Confirm with your lender before assuming an older survey will pass.

What are Table A items on an ALTA survey? 

Table A is a list of optional items that lenders or title companies can request beyond the standard ALTA requirements. Common additions include flood zone designation, parking space counts, gross land area calculations and evidence of utility service. Your lender’s closing instructions will specify which items they need.

Does every commercial deal require an ALTA survey? 

Most institutional lenders require one for any commercial transaction. Cash deals technically don’t require it, but a title company may still require one to remove survey exceptions from the policy. If any form of institutional financing is involved, plan for an ALTA survey from the start.

Who pays for the ALTA survey? 

The buyer typically pays, though this is negotiable. In larger deals, the cost is sometimes split or rolled into closing costs. Clarify the arrangement in the purchase agreement well before the closing date.
