Should I Buy a House With a Septic Tank in Georgia?

Quick answer

A septic tank shouldn’t stop you from buying a house in Georgia. Septic systems are standard in much of suburban and rural Metro Atlanta, and a well maintained one can last for decades. The real question is the condition of that specific system: Georgia doesn’t require a septic inspection when a home sells, so I would schedule one during your due diligence period, pull the county environmental health records, and confirm the system was designed for the number of bedrooms the listing claims.

Where you’ll run into septic in Metro Atlanta

Most homes inside the city of Atlanta are on public sewer. Once you move into the suburbs and outer counties, septic gets much more common. You’ll see it in much of Milton, large parts of Cherokee, Forsyth, Henry, and Douglas counties, and in older pockets of Cobb, DeKalb, and Gwinnett where sewer lines never reached.

Buyers who grew up with city sewer are often nervous about it. Here’s what I tell them: septic is a system like your roof or your HVAC. It needs occasional maintenance, it has a lifespan, and the time to understand its condition is before you’re committed to the house.

How a septic system works, briefly

Wastewater from the house flows into a buried tank, where solids settle to the bottom. The liquid then flows out to a drain field, a set of buried lines in the yard where the soil filters it. The tank needs pumping every few years to remove the solids. The drain field is the expensive part, and it’s the part most often damaged by neglect, heavy vehicles, or tree roots.

The EPA generally recommends having a household system inspected at least every three years and pumped every three to five years, depending on how many people live in the home and how much water they use.

How to check a septic system before you buy

A general home inspection usually only looks at septic from the surface. If the house is on septic, I would add a separate septic evaluation during your due diligence period. Here’s the order I’d work in:

1. Confirm the house is actually on septic. Listings aren’t always right. The county or the seller’s disclosure should tell you.
2. Request the county records. Your county environmental health office, part of the local public health district, issues septic permits. Depending on the system’s age, it may have the permit, a site drawing showing where the tank and drain field sit, and the number of bedrooms the system was designed for.
3. Ask the seller for maintenance history. Pumping receipts and any repair records tell you a lot. No records in many years is worth noting.
4. Hire a qualified septic contractor to inspect it. A thorough evaluation usually includes pumping and checking the tank, looking at the baffles and any filter, and checking the drain field for signs of failure.
5. Read the results before your due diligence period ends. That way you still have the option to negotiate or walk away. My guide to the Georgia due diligence period explains how that window works.

Red flags that should change the deal

• A bedroom count that doesn’t match the permit. Georgia septic systems are sized by bedrooms. A listing that counts a basement room as a fifth bedroom on a three bedroom system is a real issue for daily use and for any future addition.
• Wet or spongy spots, strong odors, or unusually green grass over the drain field. These can point to a struggling drain field.
• Slow drains or gurgling throughout the house. This can be a plumbing issue or a septic one. Either way, find out.
• A driveway, patio, pool, or large trees over the drain field. That can damage lines and make repairs harder.
• No records and no idea where the tank is. Not a deal breaker on its own, but it raises the importance of a full evaluation.

If problems turn up, you can ask the seller to repair the system, ask for a price reduction or a credit, or walk away within your due diligence period. My post on negotiating repairs after a home inspection covers how those conversations usually go.

Does septic affect resale value?

In areas where most homes are on septic, it tends to have little effect on price because buyers expect it. Where nearby homes are on sewer, some buyers will prefer sewer, and that can narrow your buyer pool a little when you sell. A documented maintenance history helps either way.

It’s also worth asking the county whether sewer is available on the street and what connecting would involve. Some homeowners never need to, and for others it becomes an option later.

Whether a specific septic home is a good buy depends on the system’s condition, the lot, and what else is available at your price, and that’s the kind of property by property judgment a local buyer’s agent helps with.

Living with septic after you buy

Once you own a home on septic, keeping it healthy is mostly about habits and a little scheduled maintenance.

• Know where it is. Use the county site drawing or the inspector’s notes to mark the tank and drain field, and keep vehicles, sheds, and new trees off them.
• Pump on a schedule. Put the next pumping date on your calendar based on your household size and the inspector’s advice.
• Watch what goes down the drain. Grease, wipes, and harsh chemicals are the usual culprits behind early problems.
• Spread out water use. Running several loads of laundry back to back can overload a drain field. Spacing them out helps.
• Keep records. Pumping receipts and repair invoices make your eventual sale easier, since the next buyer will ask the same questions you’re asking now.

If you’re planning a renovation, an addition, a pool, or even a new driveway, check with the county environmental health office first. Work near the tank or drain field can require approval, and adding bedrooms may require a larger system.

It’s also worth reviewing your homeowners insurance policy. Many policies don’t cover septic failure from age or wear, so a maintenance budget matters more than a claim. My guide to whether a home warranty is worth it in Georgia covers what those plans typically leave out.
