In a single-family dwelling, what is the minimum required change in elevation of the finished grade, at a point 10 feet away from the face of the foundation wall?

4 inches
6 inches
8 inches
10 inches

The correct answer is: 6 inches

In Massachusetts, the requirement for the minimum change in elevation of finished grade near the foundation of a single-family dwelling is designed to ensure proper drainage away from the building. The code mandates that the finished grade should drop by at least 6 inches within the first 10 feet from the foundation wall. This slope is crucial to prevent water accumulation around the foundation, which can lead to issues such as moisture intrusion and structural damage. The importance of this requirement is rooted in the principles of good site drainage – ensuring that rainwater and melting snow are directed away from the foundation. A gradual slope helps to reduce the chances of hydrostatic pressure building against the foundation wall, which is key to maintaining the integrity of the structure over time. By establishing a minimum elevation change of 6 inches, the code provides a clear guideline for builders and contractors, ensuring that they implement effective drainage solutions that protect the dwelling from potential water damage. This emphasis on drainage is critical in construction practices and contributes to the long-term durability and safety of residential properties.
