Radon in Federal Heights
Federal Heights is located in Adams County, which the U.S. Environmental Protection Agency designates as Radon Zone 1 — the highest-risk classification, indicating predicted average indoor radon levels at or above the EPA action level of 4 pCi/L.
Federal Heights is a home rule city, incorporated as a small (1.8 square mile) inner-ring Denver suburb. The compact footprint and 1940 incorporation date mean most of the residential stock dates to the mid-20th century — well before radon-resistant new construction (RRNC) standards became standard practice in the 1990s.
Statewide, 46.9% of pre-mitigation home radon tests in Colorado come back at or above the EPA action level (4 pCi/L), based on 214,362 tests in the CDPHE 2005–2024 statewide dataset. Whether you own or rent in Federal Heights, testing is the only way to know your home's level.
