Real Estate Radon Testing in
Brookings, SD
Brookings County is EPA Zone 2 — but that doesn't mean individual homes are safe. Many Brookings properties still test above 4.0 pCi/L, and South Dakota requires no seller disclosure. SDSU faculty and staff relocating to Brookings, along with local buyers, need a test to know what they're purchasing. We deliver results in 24 hours to keep transactions on track.

Brookings Real Estate Radon Testing Context
Zone 2 Doesn't Mean Safe — What Brookings Buyers Should Know
Brookings County is classified as EPA Zone 2, which means average predicted radon levels fall between 2.0 and 4.0 pCi/L. But Zone 2 is a county-level average — it says nothing about any individual home. Testing throughout Brookings has found properties at or above the 4.0 pCi/L EPA action level, and without a test, there's no way to know which side of that threshold a given house falls on.
The SDSU-driven real estate market in Brookings brings a steady stream of relocating faculty, researchers, and staff — many coming from states where radon disclosure or testing is more routine. In South Dakota, however, sellers have no legal obligation to provide any radon information. Buyers unfamiliar with the local landscape often discover this mid-transaction. Building the test into the inspection contingency period is the most efficient approach.
The university-adjacent neighborhoods, older construction near downtown, and newer developments on the east and south sides of Brookings all benefit from individual testing. Foundation type and sub-slab soil conditions vary enough that a next-door neighbor's test result shouldn't substitute for your own.

Yes — significantly. While Brookings County is classified as EPA Zone 2 rather than Zone 1, many homes in the area still test at or above the 4.0 pCi/L action level. Zone 2 means average predicted levels are between 2.0 and 4.0 pCi/L, but individual homes can and do exceed that threshold. Testing is the only way to know the specific level in a specific home.
No. South Dakota has no mandatory radon disclosure requirement. Buyers relocating to Brookings for SDSU positions — often coming from states with stronger disclosure laws — are sometimes surprised to find the seller is under no obligation to share any radon information. Ordering a test as part of the inspection contingency is the buyer's responsibility.
We deliver written lab results within 24 hours of device retrieval. We schedule access with listing agents, place the device in the lowest livable area, and retrieve it within the inspection period. The written report is suitable for use in transaction negotiations.
Radon levels are property-specific, not neighborhood-specific, and vary based on construction type, foundation characteristics, and soil conditions beneath any given home. While Brookings County is Zone 2, this does not mean any individual property is safe. University-area homes, older neighborhoods near downtown, and newer construction on the outer edges of the city all warrant testing.
