What does "moisture management" in the code primarily address?

Moisture management in the code is essential for ensuring the durability and safety of residential structures. It primarily addresses drainage systems and waterproofing because these elements prevent water infiltration and manage the excess moisture within building assemblies. Proper drainage effectively directs water away from foundations and living spaces, reducing the risk of mold growth, rot, and structural damage caused by trapped moisture. Waterproofing techniques further enhance a building's ability to resist water penetration, which is crucial in maintaining a dry and healthy environment within a home.

The other choices do not relate directly to moisture management. Interior decoration guidelines focus on aesthetics rather than structural integrity. Heating system installations are concerned with temperature regulation and comfort, while window size requirements relate to light and structural support, but do not address moisture issues. Moisture management is specifically concerned with controlling water and humidity levels to protect the building’s integrity and inhabitants' health.
