Colorado's unique geography and climate create specific challenges for homes and the inspectors who evaluate them. From the Front Range cities to mountain communities, Colorado homes face conditions that differ significantly from other regions.
Radon is Colorado's most significant home inspection concern. The state is classified as EPA Zone 1, meaning it has the highest radon potential in the country. Approximately one in two Colorado homes has elevated radon levels. Testing is strongly recommended for all real estate transactions, and sellers are required to disclose any known radon test results.
Foundation issues are common throughout Colorado due to expansive clay soils, particularly along the Front Range. These soils swell when wet and shrink when dry, creating movement that can crack foundations and cause structural issues over time. Foundation evaluation is a critical part of Colorado home inspections.
Colorado is in Hail Alley, experiencing significant hail storms that damage roofs and siding. Inspectors look carefully for hail damage, which may not be immediately obvious but can shorten roof lifespan significantly.
The state follows the International Residential Code with local amendments. Energy efficiency requirements are increasingly important given Colorado's temperature extremes, from cold mountain winters to hot Front Range summers.
