When a commercial property deal moves forward, most buyers expect the title report to cover everything. And it does cover a lot. A title report traces the legal history of a property, including ownership records, liens, and recorded rights. But a title report never leaves the office. It only reads documents. An ALTA land survey, on the other hand, goes directly to the property. Surveyors measure what is actually there, and what they find in the field often looks very different from what the paperwork describes.

Physical Site Conditions That Never Appear in a Title Report

A title report tells buyers who owns the property, what loans sit against it, and what rights appear in the public record. However, it cannot tell anyone what the property actually looks like today.

Surveyors who conduct an ALTA land survey visit the site in person. They measure and document all visible improvements: buildings, parking lots, fences, retaining walls, utility features, signage, and other structures on the land. All of that goes into the survey drawing, which becomes a detailed record of current conditions.

This matters because site conditions change without documentation. A parking lot expands. A new building goes up. A retaining wall gets added along the back edge of the lot. None of those changes show up in a title report if the property owner never filed them with the local government. A buyer relying only on the title report would have no record of those features, and no way to know whether they create any problems.

What an ALTA land survey documents that title reports do not:

• Buildings and structures currently on the land, including additions
• Parking lots, paved surfaces, drive aisles, and loading areas
• Fences, walls, retaining structures, and site barriers
• Utility features such as meters, transformers, and above-ground equipment
• Signage and other visible improvements not reflected in recorded documents

The ALTA land survey fills the gap between legal documents and physical reality, showing the property as it currently exists, not as older records describe it.

Unrecorded Encroachments That Can Affect Property Use

Encroachments develop gradually and often go unnoticed for years. A fence gets built without a survey, landing a few feet into the neighboring lot. A commercial building’s foundation or exterior wall extends just past the property line. A paved driveway spills onto an adjacent parcel because the owner assumed where the boundary sat.

Because these situations never get filed with any public agency, they leave no trace in recorded documents. A title report has no mechanism to find them. An ALTA land survey does. Surveyors walk the site, take precise measurements, and compare the results against the legal boundary lines. When something crosses a line, the survey notes it clearly.

Identifying an encroachment before a sale closes gives buyers the information they need to make informed decisions. A neighboring structure sitting on the property could lead to legal disputes for the new owner. An irregular fence line could complicate future site improvements. Knowing about these conditions early allows a buyer to address them directly rather than absorbing the cost of disputes or redesign work after the transaction is complete.

Types of unrecorded encroachments an ALTA survey can detect:

• Neighboring fences or walls built across the property line
• Adjacent building walls or foundations that extend onto the subject property
• Driveways or paved areas from neighboring parcels that cross the boundary
• Landscaping, grading, or retaining structures that encroach from adjoining land
• Overhanging structures such as eaves, canopies, or awnings from neighboring buildings

Access Routes and Shared Use Areas Verified in the Field

Title records can acknowledge that a shared driveway arrangement exists, but they cannot tell a buyer whether that driveway still functions the way the documents suggest. An ALTA land survey checks the physical reality of site access by having surveyors walk and measure the property directly.

Surveyors map how vehicles and pedestrians enter and exit the site. They record the layout of drive aisles, loading zones, shared parking areas, and internal circulation paths. Then they compare what they observe on the ground against what the recorded documents describe.

That comparison regularly surfaces discrepancies. A recorded easement may grant access through a shared driveway that has since been reconfigured. A structure added after the original documents were filed may now partially block an entrance. Shared parking arrangements may have shifted in ways that the legal paperwork no longer reflects accurately.

For commercial properties that have been in operation for many years, physical access conditions are among the most likely areas to diverge from recorded descriptions. Verifying them through field measurement gives buyers a realistic understanding of how the site actually functions, not just how it was documented at some point in the past.

Evidence of Property Changes That Occurred After Documents Were Filed

Most recorded documents reflect the property as it existed at a specific point in time. Owners make changes after that point, and those changes rarely trigger updates to official filings. The result is a growing gap between what records show and what the site looks like today.

An ALTA land survey closes that gap. Surveyors do not work from old drawings or rely on historical filings. They measure what is on the property during their visit and produce a drawing that reflects current conditions. Comparing that drawing against older documents reveals differences right away.

According to the American Land Title Association, changes to commercial properties frequently go undocumented for years, making field verification an essential part of the due diligence process for any transaction involving older sites. The survey drawing becomes a current baseline that neither a title report nor an older plat can provide.

What comparing current survey data against older records can reveal:

• Structures added or removed since the last recorded survey
• Paved surfaces expanded or reconfigured over time
• Site grading or drainage modifications not shown on original plans
• Improvements that may not have received proper permits
• Changes to the overall footprint that differ significantly from recorded descriptions

Survey Data That Supports Development and Operational Planning

Title reports serve a legal purpose. They say nothing about what a buyer can do with the property once they own it. ALTA land survey data fills that role instead.

Survey drawings document the precise locations of existing structures relative to property lines. They show paved surfaces, utility features, site boundaries, and any other conditions that affect how the land can be used or improved. That data becomes the starting point for planning.

A developer considering an expansion needs to know exactly how much clearance exists between the current building and the boundary lines. An engineer designing site drainage needs accurate measurements of existing grades and surface areas. A planner reviewing parking capacity needs real dimensions, not estimates pulled from outdated drawings. According to the Urban Land Institute, inaccurate site data is one of the most common causes of cost overruns in commercial development projects, making verified survey information essential before any design work begins.

Lenders also rely on ALTA survey data when evaluating whether a site can support a proposed development. A clear, current survey drawing reduces uncertainty for every party involved in the transaction.

Frequently Asked Questions

What is the main difference between an ALTA land survey and a title report?
A title report reviews recorded legal documents covering ownership, liens, and filed rights. An ALTA land survey documents physical conditions on the property today, including structures, encroachments, access routes, and site features. The two cover entirely different types of information, and neither one can substitute for the other.

Can an ALTA survey find issues that do not appear in public records?
Yes. An ALTA survey identifies visible conditions such as unrecorded encroachments, site improvements, access configurations, and physical changes to the property that no recorded document reflects.

Why do commercial property buyers often request both an ALTA survey and a title report?
The two documents address different aspects of the same transaction. The title report covers legal status and recorded rights. The ALTA survey covers physical conditions and site features. Together, they give buyers and lenders a complete picture of the property.

Can an ALTA survey detect changes made to a property years after documents were recorded?
Yes. Surveyors measure current conditions directly, so the resulting drawing reflects the property as it exists at the time of the survey. Comparing that drawing against older recorded documents highlights any modifications or additions that occurred in the intervening years.

Who uses ALTA land survey data during a commercial real estate transaction? Commercial buyers, lenders, developers, civil engineers, attorneys, and title companies all work with ALTA survey data. Each party uses it to evaluate a different aspect of the property, from legal exposure to development potential to financing risk.
