What is the maximum slope allowed for driveways according to the code?

In the context of the North Carolina Residential Code, the maximum slope allowed for driveways is designed to ensure safety and accessibility. A 12% incline is the specified maximum slope because it strikes a balance between providing adequate slope for drainage and making the driveway manageable for vehicles and pedestrians. Slopes steeper than this can pose difficulties for vehicular traffic, particularly in wet or icy conditions, and may hinder accessibility for individuals with mobility challenges.

While steeper inclines may be noted in some guidelines for specific applications, the 12% maximum is a typical standard to follow for residential driveways to minimize safety risks and enhance usability. This ensures that the driveway functions effectively in various weather conditions, preventing problems like slippage.
