The short answer
No. Georgia has no state law that requires radon testing for commercial buildings, and it has no mandate for residential buildings either. Georgia also does not license or certify radon professionals. But testing is still commonly required or expected through federal lending (HUD, Fannie Mae, and Freddie Mac), real estate transactions and due diligence, and the duty of care you owe to tenants, employees, and visitors. Four metro Atlanta counties, Fulton, Cobb, DeKalb, and Gwinnett, sit in EPA Zone 1, the highest-radon category, so elevated readings are common. The absence of a mandate does not remove the liability.

1. What Georgia state law actually says
Start with the literal question. Georgia does not have a statute or regulation that requires radon testing in commercial buildings. There is no state mandate for offices, retail, industrial space, schools, or any other commercial property type. For that matter, Georgia does not require radon testing in homes either, including during a real estate sale. If you were hoping for a single state rule that tells you when and how to test, it does not exist.
This surprises a lot of owners, because radon is a serious health hazard. It is the second leading cause of lung cancer in the United States, behind smoking. But health risk and legal mandate are two different things. Many states with significant radon exposure, Georgia included, have chosen not to legislate testing for private buildings. The practical effect is that the responsibility for deciding to test lands on the owner rather than on a state inspector.
2. Georgia does not license radon professionals
There is a second half to the no-mandate story that matters when you go to hire someone. Georgia does not license or certify radon measurement or mitigation professionals. Some states maintain a licensing board for radon work; Georgia does not. So a vendor cannot point to a Georgia radon license, because there is nothing to be licensed under.
Be skeptical of any company that claims to be a Georgia state-licensed radon contractor. No such license exists. The credentials that do carry weight are national: testing performed to ANSI/AARST protocols, and professionals credentialed through national programs such as AARST or NRSB.
Because the state does not set a credential bar, the burden of choosing a competent provider falls on you. The right questions are whether the testing follows the current national protocols and whether the professional carries a recognized national credential, not whether they hold a Georgia license that does not exist.
3. Federal lending requirements (HUD, Fannie Mae, Freddie Mac)
Here is where the no-mandate answer stops being the whole story. The most common way a commercial or multifamily owner ends up testing for radon in Georgia is not a state law at all. It is a lender. Federal lending programs reach a large share of the apartment and commercial-adjacent market, and several of them call for radon testing as part of the loan process. These requirements are federal or contractual, so they apply to the financed property regardless of Georgia's lack of a state law.
HUD finances much of the country's multifamily housing, and most of those loans treat radon as part of the environmental review. Loans for senior living and residential care facilities under HUD's Section 232 program require a signed radon report unless a specific exception applies. Fannie Mae and Freddie Mac, the two housing finance enterprises, also have multifamily radon requirements, though those changed in 2025 when the Federal Housing Finance Agency rescinded the 2022 directive that had standardized testing across both enterprises. After that change, each enterprise sets its own approach and environmental-professional judgment plays a larger role.
These program rules and any specific sampling or coverage figures are updated periodically and depend on the property and the program. Do not rely on a fixed figure you read online. Confirm the current requirement that applies to your loan with your lender before you order testing.

4. Real estate transactions and due diligence
Even when no lender requires it, radon testing shows up in commercial real estate deals through due diligence. When a commercial property changes hands, the buyer often commissions an environmental assessment. Radon is increasingly one of the items a buyer or their environmental consultant wants addressed, especially for residential and care-facility uses where occupants spend long hours indoors.
The dynamic is simple. A buyer who discovers an untested building in a high-radon area has every incentive to make testing a condition of closing, and an elevated result becomes a negotiating point on price or on who pays for mitigation. Owners who test ahead of a sale control the timeline and the narrative rather than having a late test result reopen the deal. Georgia's lack of a mandate does not make this pressure go away; it just means the market, not the state, is driving it.

5. Duty of care to tenants, employees, and parents
The third pathway is the one owners tend to overlook until it lands on their desk. A tenant asks whether the building has been tested. An employee raises a concern about air quality. A parent wants to know about radon at a daycare or school. The moment a known hazard is raised, you have notice, and notice is where a general duty of care starts to matter.
A property owner generally owes occupants a reasonably safe environment. Radon is a recognized hazard with a well-established health effect, so a documented concern that is ignored can look very different in hindsight if elevated radon is later found. This is not a Georgia radon statute. It is the ordinary liability exposure that comes with knowing about a hazard and choosing not to act. Testing is how an owner answers the question honestly, either by showing the building is fine or by addressing an elevated reading before it becomes a dispute.
6. Internal risk management and liability
Set the lender and the lawsuit aside for a moment and look at it as plain risk management. Radon is invisible, odorless, and measurable. For the cost of testing, you convert an unknown into a documented fact about your building. That record is useful in a refinance, in a sale, in an insurance conversation, and in any future dispute. The downside of testing is a modest, predictable cost. The downside of not testing is an open-ended unknown that you cannot see until someone forces the issue.
Owners who treat radon as part of routine building stewardship, rather than waiting for an external trigger, tend to spend less and stress less. A clean test result is a document you can show. An elevated result handled on your own schedule is a planned project. The same elevated result discovered by a buyer or raised by a tenant is a problem you are now solving under time pressure.
7. The EPA Zone 1 reality in metro Atlanta
The reason none of this is theoretical in Atlanta is geology. Georgia's lack of a radon law leads some owners to assume radon is not a local concern. The EPA Map of Radon Zones says otherwise. Four core metro Atlanta counties, Fulton, Cobb, DeKalb, and Gwinnett, are Zone 1, the highest category, which predicts an indoor average at or above 4.0 pCi/L. Several surrounding north Georgia counties carry elevated designations as well, driven by the region's granite and uranium-bearing bedrock.
The EPA zone map predicts averages by county. It does not tell you whether a specific building is elevated, and the EPA advises testing no matter which zone you are in. A Zone 1 county is not a guarantee of high radon, and a lower zone is not a guarantee of safety. The only way to know a building is to test it.
Put the pieces together and the picture is clear. Georgia does not require you to test, but you own a building in one of the higher-radon parts of the country, and the parties who can compel testing, lenders, buyers, and occupants raising a concern, are not bound by Georgia's silence. That combination is exactly why so many metro Atlanta commercial owners test even though no state law tells them to.
8. What this means for your building
If your property is financed through a federal program, start by confirming the current radon requirement with your lender, because that requirement is real regardless of state law. If a sale or refinance is on the horizon, plan to have a defensible test result in hand before due diligence forces the timeline. If a tenant, employee, or parent has raised radon, treat it as notice and act on it promptly rather than letting a documented concern sit.
For testing itself, look for work performed to current ANSI/AARST protocols by professionals with recognized national credentials, since Georgia does not provide a state license to rely on. If a building tests at or above 4.0 pCi/L, mitigation sized for the building reduces levels, and a retest confirms the result.
