Radon Testing for Real Estate Transactions in Georgia

Whether you're buying or selling a home in Georgia, radon testing has become a standard — and important — part of the real estate transaction process. Yet many buyers and sellers still don't fully understand what radon testing involves, when it's required, and how results can affect a sale.

This guide covers everything you need to know about radon in Georgia real estate transactions.

Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths per year. It's invisible, odorless, and can only be detected through testing. Because radon levels vary significantly from home to home — even in the same neighborhood — the only way to know a property's radon level is to test it.

For buyers, purchasing a home without knowing its radon level is a significant health risk. For sellers, proactively testing and mitigating radon can actually strengthen a listing and reduce the chance of a deal falling through during inspection.

Georgia does not have a state law mandating radon testing in real estate transactions. However, radon testing is commonly requested by buyers as part of the home inspection contingency, and many real estate contracts include radon testing as a standard inspection item.

Even without a legal requirement, the EPA recommends that all homes be tested for radon before purchase. Many mortgage lenders — particularly for FHA and VA loans — may require radon testing in high-risk areas.

As a buyer, you have the right to request radon testing during your inspection contingency period. This is typically a 7–14 day window after your offer is accepted. Make sure your purchase contract explicitly includes radon testing as a contingency.

For real estate transactions, you need a certified radon test — not a DIY kit. A certified professional uses calibrated equipment and follows EPA-approved protocols that produce legally defensible results. The test report will include the technician's certification number, test conditions, and a clear statement of the measured radon level.

At Georgia Radon Pros, we provide certified real estate radon tests with results delivered within 48 hours of test completion — fast enough to fit within most inspection windows.

If the test comes back at 4 pCi/L or higher, the EPA recommends mitigation. Here's how this typically plays out in a real estate transaction:

• Buyer requests mitigation: The buyer can ask the seller to install a mitigation system before closing, or negotiate a price reduction to cover the cost.
• Seller installs mitigation: Many sellers choose to install a system proactively to keep the deal on track. A properly installed system with a post-mitigation test showing levels below 4 pCi/L is a strong selling point.
• Buyer accepts the risk: In some cases, buyers may accept elevated radon levels and plan to mitigate after closing. This is less common and generally not advisable.

In competitive markets, buyers sometimes waive inspection contingencies to make their offers more attractive. We strongly advise against waiving radon testing specifically. Unlike many inspection items, elevated radon is a serious, ongoing health risk — and mitigation costs are predictable and manageable. Knowing the radon level before you close protects you.

The best thing a seller can do is test for radon before putting the home on the market. If levels are elevated, you have time to install a mitigation system and conduct a post-mitigation test — all before buyers start making offers.

A home with a documented radon mitigation system and a post-mitigation test showing levels below 2 pCi/L is actually a selling advantage. It demonstrates that you've been proactive about your home's health and safety, and it removes a potential deal-killer from the inspection process.

Georgia's real estate disclosure laws require sellers to disclose known material defects. If you've had a previous radon test showing elevated levels, or if you've had a mitigation system installed, you are generally required to disclose this to buyers. Failing to disclose known radon issues can expose you to legal liability after the sale.

A high radon test result doesn't mean your home is unsellable. Radon mitigation is a well-understood, cost-effective solution. A properly installed system can reduce radon levels by 90% or more, and the cost ($800–$2,500 for most Georgia homes) is modest relative to the value of the transaction.

Here's what to expect from a professional real estate radon test:

1. Scheduling: Contact a certified radon measurement professional and schedule the test. At Georgia Radon Pros, we can typically schedule within 1–2 business days.

2. Closed-house conditions: For 12 hours before and during the test, all windows and exterior doors must remain closed (except for normal entry and exit). This is required by EPA testing protocols to ensure accurate results.

3. Test placement: The monitor is placed in the lowest livable area of the home — typically the basement or first floor — for a minimum of 48 hours.

4. Results: After the test period, we retrieve the monitor and provide a certified test report, typically within 24 hours.

5. Next steps: If levels are at or above 4 pCi/L, we'll walk you through your mitigation options and provide a free estimate.

Buyers of new construction homes should also request radon testing. Many new homes in Georgia are built with radon-resistant new construction (RRNC) features — passive vent pipes, sealed foundations — but these features don't guarantee low radon levels. Only testing can confirm whether the system is working effectively.

If a new home tests high, the passive system can often be activated by adding a fan, which is less expensive than a full mitigation installation in an existing home.
