Buying an Older Home in Atlanta: 7 Things to Check First

A house in Grant Park or Virginia-Highland can have stone steps, a terraced yard, and fresh retaining walls — and still have water working against it every time it rains. For anyone buying an older home in Atlanta, the problems that cost tens of thousands of dollars rarely show up on the listing photos. They sit under the yard, behind the drywall, and in the HOA’s filing cabinet.

Here is what to check, in plain terms, before the inspection period runs out.

Is Atlanta’s Red Clay Bad for Foundations?

Not usually by itself. The bigger risk on an Atlanta lot is water management, not soil expansion.

Atlanta sits on the Piedmont Plateau, and the red soil most people call “Georgia clay” is dominated by kaolinite, a clay mineral with a low shrink-swell rating. That matters because a lot of foundation-repair marketing treats red clay as inherently expansive. What actually drives foundation movement here is water: rain coming off the roof, moving across a sloped lot, and collecting where it shouldn’t.

On hillside lots in Buckhead, Brookhaven, Sandy Springs, Kirkwood, or anywhere with grade changes, buyers should walk the property with three questions:

• Are downspouts emptying right beside the foundation instead of being carried away?
• Is any retaining wall holding back more soil than it was designed for — leaning, bowing, or weeping at the base?
• Does the grading send runoff toward the house instead of away from it?

Which Foundation Cracks Should Worry an Atlanta Buyer?

Horizontal cracks, bulging walls, and separation where the house meets the foundation are the ones that justify a structural engineer.

Stair-step cracks in exterior brick and hairline cracks above interior doors are common in older Atlanta homes and often come from normal settling. A horizontal crack in a foundation wall, a wall that is starting to bow inward, or a visible gap at the foundation line is a different category. At that point, buyers should request every available repair record and bring in a licensed structural engineer before moving forward — ideally inside the due diligence period, not after.

Who Pays for the Sewer Line in Atlanta?

In the City of Atlanta, the sewer lateral connecting the house to the city’s sewer is the property owner’s responsibility to maintain and repair. That makes a sewer scope one of the highest-value checks a buyer can order.

This is not only an East Atlanta or Grant Park issue. Intown Atlanta has a deep stock of historic homes, and many still have original clay sewer pipe. Age alone doesn’t condemn a line — a 1940s bungalow may have a line that was replaced years ago. What matters is the condition of that specific line, whether anyone has scoped it before, and whether mature trees sit along its path. Roots find the joints in old clay pipe and work their way in.

A sewer scope is separate from a standard home inspection and typically costs a few hundred dollars more. It either gives the buyer a concrete repair issue to negotiate or confirms the line is in good shape. Buyers should also read their homeowner’s policy rather than assume it covers a sewer line failure; many policies require a separate service line endorsement.

What Pipes and Materials Should Buyers Ask About by Build Date?

For homes built from 1978 through the mid-1990s, buyers should ask specifically about polybutylene water supply lines.

Polybutylene (PB) is a gray plastic supply pipe that was installed widely from 1978 to 1995, especially across fast-growing Sun Belt suburbs. Not every PB system has failed, but the material can break down over time, particularly with chlorinated municipal water, and its failures led to a $950 million national class action settlement (Cox v. Shell Oil) in 1995. Because most supply lines run behind walls, PB is easy to miss on a walkthrough. Buyers should ask the inspector to name the supply pipe material in the written report.

The same era produced other products tied to class action lawsuits, including certain hardboard and OSB siding lines from manufacturers such as Georgia-Pacific and Louisiana-Pacific, and early synthetic stucco (EIFS). The build date tells a buyer which questions to ask: what materials were used, what has already been replaced, and whether there are records for that work.

How Can Buyers Tell If an Atlanta HOA Is Underfunded?

Read the documents. An older HOA isn’t a red flag by itself; an HOA that can’t explain how it will pay for upcoming repairs is.

Metro Atlanta has many communities built in the 1980s and 1990s that are now reaching the point where roofs, pools, retaining walls, and paving need major work at the same time. Georgia’s Property Owners’ Association Act and Condominium Act don’t require associations to conduct reserve studies, so whether one exists depends on the community’s governing documents and lender requirements. An underfunded association can leave owners with a special assessment they never planned for.

Before removing any contingency, buyers should request:

• The last two years of board meeting minutes
• The current budget
• Any reserve study or engineering report the association has completed
• Details on any special assessment under discussion — what it covers, the total project cost, and whether work has started

Do Mature Trees, Squirrels, and Crawl Spaces Really Matter?

Yes — Atlanta’s tree canopy is a feature, but it needs to be inspected like any other system on the property.

Atlanta is called “the city in a forest” for good reason. But a mature oak shading the porch can also be rubbing shingles off the roof, sending roots toward the sewer line, and lifting sections of the driveway. If a large tree overhangs the house, a certified arborist can say what should be trimmed, monitored, or removed.

That same canopy brings squirrels close to the roofline. Once inside an attic, they chew insulation and wiring, which turns a nuisance into a fire risk. Chewed wood or droppings during a showing are worth an attic inspection and, if needed, a wildlife professional who will both remove the animals and seal the entry points.

Finally, many Craftsman bungalows and Victorians were built over open crawl spaces that let moisture move through and dry out. Many have since been enclosed. An enclosed crawl space isn’t automatically a problem, but if the water path wasn’t fixed first, moisture can get trapped under the house. A plastic liner is not proof the crawl space is dry.

From Valerie: The Questions I Ask Before Any Client Moves Forward

Valerie Gonzalez has sold intown Atlanta homes for 29 years and closed more than 600 transactions.

“I don’t tell buyers to walk away from older homes, hillside lots, or 1980s HOAs. Some of the best houses in this city are all three. What I tell them is to know what they’re buying before they’re committed. On every older home, I want to know where the roof water goes, whether the sewer line has been scoped, what the supply pipes are made of, and what the HOA is planning to spend money on. None of those answers come from the listing. Once you have them, you can negotiate, plan, or move on — and all three are good outcomes compared with finding out after closing.”

Frequently Asked Questions

Does red clay cause foundation problems in Atlanta? Red clay alone is rarely the main cause. Most Piedmont clay around Atlanta is kaolinite-based with a low shrink-swell rating; poor drainage, roof runoff, and overloaded retaining walls are the more common drivers of foundation movement.

Who is responsible for the sewer line in the City of Atlanta? In the City of Atlanta, the property owner is responsible for maintaining and repairing the sewer lateral that connects the house to the city’s sewer. Buyers should order a sewer scope before closing, especially on older homes with mature trees.

How much does a sewer scope cost in Atlanta? A sewer scope generally adds a few hundred dollars on top of a standard home inspection. It uses a camera to show the line’s condition, root intrusion, and breaks before the buyer commits.

What years were polybutylene pipes used? Polybutylene supply pipe was installed in U.S. homes from roughly 1978 to 1995. Buyers looking at homes from that period should ask the inspector to identify the supply pipe material by name in the written report.

Does homeowners insurance cover sewer line repairs in Georgia? Not always. Many standard homeowner’s policies exclude service line failures unless the owner adds a service line endorsement, so buyers should read the actual policy before relying on coverage.

Are HOAs in Georgia required to have reserve studies? No. Georgia’s Property Owners’ Association Act and Condominium Act do not mandate reserve studies; any requirement comes from the association’s governing documents or lender guidelines. Buyers should request the reserve study, budget, and recent board minutes.

Is an enclosed crawl space a problem in an older Atlanta home? Not automatically. The key questions are where roof runoff goes, whether the yard slopes away from the foundation, and whether the ground under the house stays dry — a vapor barrier alone doesn’t confirm that.
