You just bought a brand-new home in a Northeast Ohio subdivision. The builder's warranty is in your folder, the paint is fresh, and the last thing on your mind is radon. After all, it's a new house.
That logic is exactly backwards. And it's why we test new construction for radon just as often as we test century-old farmhouses.
Radon comes from the ground, not the house. It's produced by the natural decay of uranium in the soil and bedrock beneath your foundation, and it seeps upward through any gap it can find — cracks in the slab, pipe penetrations, sump pits, the joint between the floor and the wall. The age of the house is irrelevant. What matters is what's in the ground underneath it.
Northeast Ohio sits in EPA Radon Zone 1, the highest-risk category in the country. That designation is based on geology, not housing stock. The same glacial deposits and shale formations that put older homes at risk put your new subdivision at risk too.
Here's the counterintuitive part: modern, energy-efficient homes are often tighter than older ones. Better insulation, better windows, better air sealing. All of that is good for your energy bill. But it also means less natural air exchange, which means radon that seeps in has fewer ways to get back out. Tighter construction can concentrate the gas faster than a drafty older home would.
Many new Ohio subdivisions are built with passive radon-resistant construction — a layer of gravel under the slab, a plastic vapor barrier, and a vertical pipe stubbed up through the roof. Builders sometimes present this as a radon solution. It isn't. It's a radon-ready infrastructure that makes future mitigation easier and cheaper if it's ever needed.
Passive systems reduce radon entry but do not guarantee safe levels. The only way to know whether your new home is safe is to test it. A passive system with a fan added (making it active) is a real mitigation system. A passive system without a fan is just a pipe.
If your builder installed a passive radon system, test the home within the first year. If levels come back at or above the EPA action level of 4.0 pCi/L, you may be able to have the builder activate the system under warranty — adding a fan to the existing pipe at their cost rather than yours. That window closes when the warranty does.
A radon test takes 48 hours and costs far less than activating a mitigation system after the fact. It's the right move whether you're buying new construction or have been living in your home for years without ever testing.
