Which of the following is a requirement for exterior stairs maintenance?

Exterior stairs maintenance includes several safety and structural requirements to ensure the stairs are safe for use. One critical requirement is the inclusion of handrails if the stairs have more than four risers. This guideline is in place to enhance safety, as handrails provide support and stability for individuals using the stairs, particularly when navigating multiple steps.

Handrails must meet specific design and construction standards, including height and graspability, to be effective and safe. The requirement to install handrails serves to reduce the risk of falls and accidents, making it an essential aspect of stair maintenance in compliance with safety codes.

The other options do not align with the safety and construction standards outlined in property maintenance codes, as they do not address key safety features or the structural integrity of stairs. Therefore, the necessity of handrails for exterior stairs with multiple risers is not just a recommendation but a mandated requirement for proper maintenance and safety.
