What is the maximum riser height for Group A dwellings under PD 1096?

The maximum riser height for Group A dwellings under PD 1096 is established at 200 mm. This standard is in place to ensure safety and accessibility in residential buildings, as excessively high risers can pose a tripping hazard and make it more difficult for individuals, especially those with mobility challenges, to navigate stairs safely.

Building codes often dictate specifications for features like stair risers to promote a safe environment. The 200 mm limit is intended to balance aesthetic considerations, construction standards, and the practical needs of residents. Adhering to these guidelines ensures uniformity and safety across all Group A dwellings, which typically include residential buildings such as single-family homes and apartment complexes.

This correct limit also reflects broader best practices that are recognized in various building codes to enhance the livability and safety of homes. The choice of a maximum riser height of 200 mm is preferred over lower options since it accommodates a wider range of building designs while still prioritizing user safety.
