Radon in Arvada: What You Need to Know

Arvada sits at approximately 5,350 feet in Jefferson County — solidly within Colorado's EPA Zone 1 radon designation, the highest-risk category. The city's housing stock tells the radon story: a mix of 1950s and 1960s ranch-style homes with full basements, 1970s and 1980s construction with slab-on-grade or partial basements, and newer development pushing toward the foothills. Many of the older ranch homes were built on expansive clay soils — the same Front Range geology that traps radon gas beneath slabs before it enters the living space.

The Ralston Creek corridor and established neighborhoods near Arvada Center tend to have the oldest housing stock, with the highest rate of basement-finished homes where radon accumulates most. Newer communities like Candelas and Whisper Creek on the western edge are built on similar soils at higher elevation — elevated radon risk regardless of construction year.

Arvada also has an active real estate market. The combination of family-sized homes, good schools, and proximity to both Denver and the mountains drives transaction volume — and radon flagged in an inspection is a common closing obstacle we help resolve every week.
