A multi-tenant building can look simple from the parking lot. On paper, it rarely is. Buyers often think they’re getting one clean block of land with a few tenants inside. An ALTA land survey shows what you’re actually buying before you sign. It maps the real boundaries, the shared spaces, and the rights that come attached to the site. By the end of this article, you’ll see how that one document protects both your money and your plans.

Understanding What the Buyer Actually Controls

An ALTA land survey helps you tell apart the land you’re buying from the land that only looks like yours. Some driveways, walkways, or parking spots may sit on a neighbor’s parcel. Others may belong to you but sit under an easement that limits what you can do. The survey draws these lines so you know the true edges of your site.

This matters more with multiple tenants. Each tenant uses space every day, and they treat it all as part of the building. A buyer needs a clearer picture than that. The survey shows the parcel you’ll own and control after closing, not just the space people walk on.

Ask your surveyor to flag any improvement that crosses a boundary line. Mark those spots on your site plan early. They often turn into the first real questions in a deal.

Tracing Shared Access and Parking Rights

Multi-tenant properties run on shared roads, driveways, loading zones, and parking. One tenant may need a back drive to receive trucks. Another may rely on parking that sits partly on the next lot. An ALTA land survey ties these areas back to recorded easements and property lines.

That link is where risk hides. An access route may depend on a neighbor’s permission that can end. A parking area you counted on may belong to someone else. When you know who holds each right, you can plan around it instead of finding out after closing.

Compare each shared-use area on the survey against the recorded easements in your title report. Any gap between the two deserves a call to your attorney. Shared access problems are cheaper to fix before you own the building.

Comparing Tenant-Facing Improvements With the Legal Site

What tenants see and what the deed says don’t always match. Fences, signs, sidewalks, drive aisles, and parking stripes get added over the years. Nobody checks the survey when they pour new concrete. Over time, the built site drifts away from the legal one.

An ALTA land survey puts both pictures side by side. You can see where a sign sits inside an easement, or where a fence crosses onto the next parcel. These small mismatches can create big questions about who owns, maintains, or can remove each feature. For a buyer planning to hold the property for years, those answers shape real costs.

Why this matters for developers

Developers care about what they can change later. A parking island in the wrong spot can block a future drive-through tenant. A shared wall or shared drainage line can slow a remodel. Spotting these on the survey now saves redesign work down the road.

Finding Site Constraints That Could Affect Future Tenant Plans

Buying a multi-tenant building isn’t only about today’s rent roll. You may want to add parking, expand a wing, move an entrance, or split a suite later. Every one of those moves depends on the land under the building. An ALTA land survey gives you a measured view of easements, rights-of-way, setbacks, and existing improvements that could get in the way.

Say you want to add ten parking spaces in three years. The survey may show a utility easement running right through the spot you picked. That single line can send you back to the drawing board. Better to learn it now, while the price is still open for talks.

Bring your future wish list to the survey review, not just your current one. Ask the surveyor to show you where easements and rights-of-way limit new work. A property that can grow is worth more than one that’s boxed in.

Using Survey Findings to Test the Deal Before Closing

The survey earns its keep when you line it up against everything else. Put it next to the title commitment, the leases, the site plans, and your own plans for the property. When the physical site and the records disagree, you’ve found something worth checking. That mismatch is your early warning system.

A few examples make this real. A lease may promise a tenant twenty parking spaces the site can’t legally provide. A title exception may point to an easement that blocks your expansion. Each of these is easier to price, fix, or walk away from before the deal closes.

Treat the ALTA land survey as one part of your due diligence, not a box to check. Share it with your lender, attorney, and title company at the same time. The sooner they all see the same map, the fewer surprises show up at the closing table.

Frequently Asked Questions

Do I really need an ALTA survey for a multi-tenant purchase?

Most commercial lenders and title companies will ask for one on a multi-tenant deal. Even if nobody requires it, the survey can still pay for itself. It catches parking, access, and boundary problems while you can still act on them. Skipping it means you may inherit those problems as the new owner.

How long does an ALTA land survey take?

Timing depends on the size of the site, the number of tenants, and how fast the surveyor gets records. Many commercial surveys take a few weeks from order to final map. Complex sites with many easements can take longer. Order it early in your due diligence so it does not become the reason a closing slips.

What is Table A on an ALTA survey?

Table A is a list of optional items you can add to the survey. It covers things like parking counts, building measurements, zoning notes, and utility locations. You pick the items that matter for your deal. For a multi-tenant building, parking and improvement details are often worth adding.
