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.

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.
