The 60540 area includes downtown Naperville and the Historic District, where many homes predate modern building practices. Older foundations — and later additions on slabs or crawlspaces — can mean a system needs more than one suction point. If your home is in the Historic District, ask whether exterior pipe placement needs any review before installation.

What IEMA's radon test records show for ZIP 60540

IEMA publishes radon results reported by licensed measurement professionals. For test addresses in ZIP 60540, we counted 6,451 valid tests on homes without a mitigation system; 49% were at or above EPA's 4.0 pCi/L action level.

For comparison, 42% of tests were at or above 4.0 pCi/L across the 26 DuPage-area and nearby cities we pulled from the same data, so ZIP 60540 is above that average. These are mostly real-estate and homeowner-ordered tests, not a random sample, so they can't predict your house — neighbors on the same block can test very differently. The only way to know is to test your own home.

Housing in Naperville and what it means for radon

About 149,540 people lived in Naperville in the 2020 Census. The median home there was built around 1990, and the biggest share of its housing went up between 1990 and 2009 (11% before 1970, 40% from 1970–1989, 41% from 1990–2009, 8% since 2010). Roughly 63% of homes are detached single-family houses and 12% are townhouses or other attached single-family homes; about 75% of households own their home.

About 8% of Naperville homes were built since 2010. Illinois' Radon Resistant Construction Act has required a passive radon pipe in new homes since June 1, 2013, so a newer house may already have a capped vent pipe. If it tests high, a licensed mitigator can often add a fan to that pipe instead of building a whole new system — usually the cheapest fix.

Next steps in ZIP 60540

  1. If you haven't, run a short-term test in the lowest lived-in level (EPA guidance). For a home sale, use a licensed measurement professional.
  2. If you're at or above 4 pCi/L, get a quote from an IEMA-licensed mitigator — Illinois requires the license for paid mitigation work.
  3. After installation, retest to confirm the level dropped.
