“Smoke Alarm Regulations for Rental Property” by Frank C. Carnahan

Owners of residential rental property inside Springfield must have one smoke detector in each bedroom, one in the common hall to the bedrooms and one on each dwelling floor. For dwellings constructed after April 2, 2001, smoke alarms must be electrically powered and interconnected so all alarms sound if one is set off. Smoke alarms that communicate wirelessly by infrared are available so that re-wiring through walls is not required.
