    Healthy Homes for Indiana — High-Radon Counties and Rural Air

    • Elevated county radon

      A large share of Indiana counties fall in the highest EPA radon zone, and finished basements put living space right at the entry point.

    • Agricultural drift and rural air

      Rural Indiana homes near active fields take in seasonal dust and spray drift through leaky envelopes and unfiltered air paths.

    • Wet-cold winters in leaky stock

      Indiana's older houses lack continuous air control, so warm indoor humidity condenses inside the wall during long cold spells.

    What Climate Zone 5A Means for Indiana Homes

    Indiana's Zone 5A climate combines humid summers with cold winters over glaciated soils and southern limestone karst. Radon runs high in a large share of Indiana counties, especially where karst and glacial till meet. Agricultural drift and unvented combustion appliances add rural indoor air issues that urban code discussions tend to skip.

    • Indiana Residential Code and Indiana Energy Conservation Code

      Indiana adopts amended IRC and IECC editions statewide through the Fire Prevention and Building Safety Commission.
