Condensate will be drained to daylight or a condensation pump

Maintain a dry basement

Reduce conditions conducive to mold growth, wood rot, and pests

2.0404.4b
Dehumidification for divided spaces

Drying will be provided to all basement areas

Maintain a dry basement

Reduce conditions conducive to mold growth, wood rot, and pests

2.0404.4c
Relative humidity

All basement spaces will be maintained at a relative humidity that ensures condensation will not occur on cool surfaces

Maintain a dry basement

Reduce conditions conducive to mold growth, wood rot, and pests

2.0404.4d
Condensing surfaces(e.g., cold water pipes)

Condensing surfaces in basement will be insulated and sealed

Maintain a dry basement

Reduce conditions conducive to mold growth, wood rot, and pests

2.0404.4e
Dehumidification (option for dry climates and heating- dominated climates seasonally)

Ventilation in the basement will be controlled to maintain relative humidity that ensures condensation will not occur on cool surfaces
