What is the minimum requirement for perimeter drainage from beneath and around a home?

The minimum requirement for perimeter drainage from beneath and around a home being set at 0.25 inches per foot is crucial for effective water management. This specification ensures that water can efficiently drain away from the foundation of the home, which helps prevent issues such as flooding, soil erosion, and structural damage. Proper drainage is essential in maintaining the integrity of the home and ensuring a dry, stable environment.

This standard allows for adequate flow without overburdening the drainage systems, which could lead to blockages or other complications if the slope were too steep. Maintaining a gentle slope of 0.25 inches per foot is typically sufficient to channel away water effectively, ensuring that runoff does not accumulate around the foundation and that the home remains protected from moisture-related problems.
