Buying commercial property is not always as simple as one deed and one parcel. Many deals involve two, three, or more separate parcels bought together. Shopping centers, office parks, warehouses, and development sites are common examples. When that happens, an ALTA survey does more than look at each piece of land on its own. It checks how the parcels fit together, and that is where many buyers run into surprises.

What Makes Multi-Parcel Properties Different

A property with one parcel has one deed, one legal description, and one set of boundary lines. A property made up of multiple parcels has several of each, and they do not always match.

Each parcel may have been created at a different time. It may have passed through different owners and been described in a deed written by a different person. One deed might describe a parcel edge differently than the deed for the parcel right next to it. What looks like one connected piece of land on a map can have hidden gaps, overlaps, or conflicts buried in old records.

A basic boundary survey looks at each parcel on its own. An ALTA survey looks at all of them together and finds where the problems are between them.

5 Problems an ALTA Survey Finds in Multi-Parcel Deals

1. Gaps and Gores Between Parcels

When two parcels are supposed to share a boundary line, the survey checks whether they actually do. A gap is a strip of land between two parcels that does not belong to either of them. A gore is similar. It is usually a thin, wedge-shaped piece of land that appears when two deed descriptions do not line up exactly.

If a gap exists between parcels you are buying, you may not own all the land you think you are buying. That unclaimed strip can cause problems with building placement, parking, or getting from one part of the site to another.

ALTA/NSPS survey standards require the surveyor to find and report any gaps or overlaps between parcels when a survey covers more than one deed. This rule exists because gaps and gores are common in commercial properties that were put together from multiple older purchases.

2. Overlapping Descriptions

An overlap is the opposite of a gap. It happens when two parcels both claim the same strip of land. This can occur when old deeds used vague landmarks, or when land was split up and the paperwork was not updated carefully.

An overlap means two different parties may have a legal claim to the same ground. That is a title problem that has to be fixed before the property can be financed or built on. An ALTA survey puts all the parcel descriptions on one drawing together. For many buyers, that is the first time the conflict has ever been visible in one place.

3. Contiguity: Do the Parcels Actually Touch?

Contiguity means the parcels actually touch each other with no breaks between them. A property can look connected on a map but not be legally connected at all. If parcels are not contiguous, they cannot be used as one development site. Lenders and title companies require proof that the parcels form one connected piece of land. The ALTA survey confirms this by measuring where each parcel’s boundaries fall and certifying whether they meet.

4. Buildings and Improvements That Cross Parcel Lines

Many commercial properties were built years before the current buyer arrived. During that time, improvements were put in without much thought about which parcel they sat on. A parking lot may span two parcels. A building may sit on a boundary line. A driveway may run along a line that legally belongs to one parcel but is used by both.

When structures or improvements cross parcel lines, they create problems for the buyer, the lender, and the title company. The ALTA survey shows exactly where every improvement sits in relation to each parcel’s recorded boundary lines. This brings conflicts to the surface before closing, rather than during construction or financing.

5. Easements That Conflict Across Multiple Deeds

Each parcel may have its own recorded easements. An easement gives someone else permission to use part of your land for a set purpose. When multiple parcels are combined, all easements must be reviewed together. One parcel’s easement may conflict with plans for the parcel next to it. Two easements from different deeds may overlap in a way that limits building across the full site. The ALTA survey puts all easements from all parcels on one drawing, giving buyers and attorneys a complete picture that no single deed can show.

How Title Insurance Works for Multi-Parcel Properties

Title insurance on a multi-parcel property works differently than on a single parcel. Title companies issue a contiguity endorsement, which confirms that the parcels are connected with no gaps between them. Without it, the policy may not cover losses from gaps, gores, or boundary problems. The ALTA survey makes the endorsement possible. The title company cannot issue one without a current survey confirming that all parcel boundaries meet and no unclaimed land sits between them.

One Survey for All Parcels or Separate Surveys?

Buyers sometimes ask if each parcel needs its own survey. In most commercial deals, the surveyor prepares one ALTA survey covering all parcels as a group. This shows how every parcel relates to the others in one drawing, which is the only way to spot gaps, overlaps, and shared improvement problems. It also gives lenders and title companies one certified document instead of several to cross-check. One combined survey is usually less expensive too.

How Much Does a Multi-Parcel ALTA Survey Cost?

Multi-parcel ALTA surveys cost more than single-parcel surveys because they involve more deed research, more fieldwork, and more complex analysis. In Georgia, these surveys generally start at $3,500 and can go above $8,000 depending on the number of parcels and how complex the records are. Fixing a gap or overlap after closing almost always costs far more.

Frequently Asked Questions

What is a gore in a land survey? 

A gore is a thin strip or wedge of land that falls between two parcels because their deed descriptions do not line up exactly. Gores can go unnoticed for years because they do not show up on a basic map review. An ALTA survey finds gores by comparing all parcel descriptions against each other and against actual field measurements, then reports them to the buyer and title company before closing.

Do all parcels in a multi-parcel deal need their own title commitment? 

Yes. Each parcel has its own recorded history, so a separate title commitment is prepared for each one. The surveyor uses all of them together when preparing the ALTA survey. This matters because easements, liens, or other issues may show up in one parcel’s records but not in another’s, even though both will be part of the same purchase.

What happens if two parcels in a deal are found to be non-contiguous? 

If parcels do not touch, the title company cannot issue a contiguity endorsement, and most lenders will not approve financing for the combined site. The seller can work with an attorney and surveyor to fix the descriptions and close the gap. The buyer can also ask for a lower price to account for the title problem. In some cases the deal structure has to change. Finding this during due diligence is the only time the buyer has real options.

Can an ALTA survey be used to combine multiple parcels into one legal description? 

The survey does not legally merge the parcels on its own. However, it gives an attorney the accurate boundary data needed to write a new combined legal description. In Georgia, combining parcels usually requires a deed of combination or a lot consolidation plat filed with the county. A surveyor can explain what steps are needed based on the property and Carroll County’s rules.
