In home inspection terminology, what is the purpose of the tread?

The purpose of the tread in home inspection terminology is to provide a walking surface on stairs. Treads are the flat, horizontal parts of the stair that individuals step on when ascending or descending. They are critical for ensuring safe and secure footing, as they determine the effective width and depth that can support a person's weight. Properly sized treads contribute not only to safety but also to the overall usability and comfort of the stairway. In assessing the integrity of stairs during a home inspection, evaluating the condition and dimensions of the treads is essential to ensure compliance with building codes and safety standards.
