What safety feature is generally required in habitable rooms in addition to receptacle outlets?

In habitable rooms, the installation of smoke alarms is a critical safety feature mandated by code to enhance occupant safety. Smoke alarms provide an early warning system in case of fire, significantly reducing the risk of injury or fatality by alerting residents to the presence of smoke before it becomes a more serious, life-threatening situation. This proactive measure is essential in ensuring that individuals have adequate time to evacuate the premises when necessary.

While indoor lighting fixtures, temperature control systems, and fire exits are also important for comfort and safety within living spaces, they do not specifically address fire detection or alerting occupants in the event of smoke or fire. Therefore, the inclusion of smoke alarms is a distinct requirement that serves a crucial purpose in safeguarding those who live in these environments.
