Brandon sits directly east of Sioux Falls along the I-90 corridor — fully within Minnehaha County's Zone 1 radon risk area. Whether your home is 30 years old or 3, the soil beneath it produces radon at elevated levels.
Brandon's housing stock spans several decades — from established 1980s and 1990s neighborhoods to newer subdivisions built in the 2010s and beyond. The radon risk doesn't favor one vintage over another. Minnehaha County is designated EPA Zone 1 across the board, and Brandon's geology reflects that rating consistently.
Older Brandon homes often have never been tested. Their basements have been accumulating radon exposure for years without the homeowner knowing. Newer homes are frequently better sealed, which can actually concentrate radon at higher levels than a drafty older structure.
Home sales in Brandon feed the same real estate disclosure pipeline as the rest of the metro — every transaction triggers a test, elevated results require mitigation, and the cycle runs twelve months a year with no seasonality.
