Step-by-step explanation:
The question pertains to the regulations surrounding stair safety and the requirement of railings. Based on building codes, such as those defined by the International Building Code (IBC) and local building codes, it is generally true that you need a railing if there are four or more risers or the stairs have a vertical height of more than 30 inches. The reason behind this requirement is to ensure that there is sufficient support for individuals using the stairs to prevent falls and injuries.
True. According to many building codes and safety standards, a railing is typically required when there are four or more risers on stairs or when the vertical height of the stairs exceeds 30 inches. The purpose of the railing is to enhance safety by providing support and preventing falls.
The specific requirements may vary by jurisdiction, but the general principle is to ensure that staircases meet safety standards to protect individuals using them. It is essential to consult local building codes and regulations to determine the specific requirements for stair construction and the installation of railings in a given area.
