Questions

Does a radon contractor need a license in Colorado?

Yes. Since July 1, 2022, all radon measurement and mitigation in Colorado must be done by a professional licensed through DORA's Office of Radon Professionals. Measurement licenses start RME- and mitigation licenses start RMT-.

Source: Colorado DORA press release, Aug. 16, 2022; DORA Office of Radon Professionals. Checked 2026-11-05.
Do I have to test for radon to sell a house in Colorado?

No test is required. Since Aug. 7, 2023 (SB23-206), home sale contracts carry a radon warning, sellers must disclose what they know, and CDPHE's radon brochure is required for sales and rental agreements.

Source: SB23-206; CDPHE, Radon and real estate. Checked 2026-11-05.
Do new homes in Parker have to be radon-resistant?

Not under state law: Colorado has no statewide building code, so it depends on your local code. Boulder, Longmont, Louisville, Erie, Superior and unincorporated Boulder County require radon-resistant construction in new single-family homes, and a trade-group list (as of Sept. 2021) names about 40 cities and 19 counties with a radon appendix. Check with your building department.

What radon level should I act on?

EPA recommends fixing a home at 4 pCi/L or higher and suggests considering a fix between 2 and 4 pCi/L. What your test number means →
