Which of the following is a requirement for smoke alarms in multiple dwelling units?

Smoke alarms in multiple dwelling units are required to be installed on every level, including basements. This requirement is crucial for ensuring the safety of occupants, as smoke can spread quickly through a building and may originate from any level. By having smoke alarms on each level, the likelihood of early detection of smoke or fire is significantly increased, thereby providing additional time for residents to evacuate the premises safely.

While having additional alarms in specific areas, such as the kitchen, may seem beneficial, it does not satisfy the broader requirement to cover all levels. Similarly, limiting smoke alarms to guest rooms or only having one alarm per unit would compromise the overall safety standards established for multi-residential properties. The goal is to ensure comprehensive coverage and prompt alerts throughout the entire dwelling to enhance occupant safety.
