Generally, in a rental property a smoke alarm must be installed in every hallway near a bedroom and on each level of a multistorey home. These are minimum requirements and owners are encouraged to install additional smoke alarms to increase the level of early warning for tenants in the event of a fire.
Fire Services strongly recommend placing a smoke alarm in each sleeping area (bedroom), hallway, living area and at the top of stairways.
