Under Michigan Building Code, which of the following best describes the required placement of smoke detectors in a new single-family residence?
Correct Answer
A) Inside each bedroom, outside each sleeping area, and on every level
Michigan Building Code requires smoke detectors inside each bedroom, outside each sleeping area in the immediate vicinity, and on every level of the dwelling.
Why This Is the Correct Answer
Michigan Building Code aligns with the IRC requirement for smoke alarms to be installed in three locations: (1) inside each sleeping room (bedroom), (2) outside each separate sleeping area in the immediate vicinity of the bedrooms, and (3) on every level of the home including the basement. This multi-layered approach maximizes early warning.
Why the Other Options Are Wrong
Option B: One detector per floor level only
One detector per floor level is insufficient. This approach misses the critical inside-bedroom and outside-sleeping-area requirements. A single detector per floor does not satisfy Michigan or IRC smoke alarm placement standards.
Option C: In hallways and living areas only
Hallways and living areas only is incorrect. While hallways near bedrooms are part of the required placement, living areas alone do not satisfy the code. Detectors are specifically required inside bedrooms and on every level.
Option D: Outside sleeping areas and in the basement only
Outside sleeping areas and in the basement only is incomplete. It omits the requirement for a detector inside each bedroom. The inside-bedroom requirement has been codified to address the growing use of solid-core bedroom doors that can contain smoke.
Memory Technique
Use the 'IOE' rule: Inside each bedroom, Outside sleeping areas, Every level. IOE = Inside, Outside, Every floor.
