Above grade walls are required to be at least what percentage above grade?

The requirement for above-grade walls to be at least 50% above grade aligns with standard building practices and safety regulations. This percentage ensures that a significant portion of the wall is elevated above the surrounding ground level, which helps protect the structural integrity of the building from moisture intrusion, pests, and other environmental factors. Additionally, this height ensures that the foundation and lower portions of the structure are not exposed to water, particularly during heavy rainfall or flooding, which is crucial in areas with potential water infiltration issues. Following these guidelines contributes to the overall durability and resilience of residential structures, making it a critical consideration in the construction process.
