What should be observed to determine the condition of stairs?

To determine the condition of stairs, it is essential to observe the uniformity and stability of steps and handrails. Stability is critical for safety—unstable steps can pose serious risks of slips and falls, which are common hazards in homes. The uniformity of the steps ensures that each step is consistent in height and depth, allowing for safe navigation on the staircase. When handrails are firm and securely attached, they provide necessary support for individuals as they ascend or descend, further enhancing safety. Assessing these factors is crucial for identifying potential safety hazards in a home inspection scenario.

Observing the width of stair treads, while important for comfort and safety, does not directly provide a complete picture of the overall stability or safety of the stairs. The color and style of materials used may be relevant for aesthetic purposes but do not affect functionality and safety. Lastly, while the distance between each step (rise and run) contributes to stair safety and ease of use, the observation of uniformity and stability encompasses a broader range of important safety aspects, making it the key focus in assessing stair conditions.
