When is a smoke detector required in a residential garage?

A smoke detector is required in a residential garage if it is attached to the home or contains appliances that could produce combustion fumes. This requirement is based on the understanding that garages can be sources of combustion gases, especially if they contain vehicles or tools that run on gas, or appliances such as water heaters.

When a garage is attached to the living space, it presents an increased risk for the spread of smoke and gases into the home. Therefore, having a smoke detector in such areas ensures that residents are alerted in the event of a fire or hazardous situation, allowing them to take action to protect themselves and avoid potential tragedies.

In the context of the other considerations, while some might think that smoke detectors should be in all garages regardless of attachment or contents, the regulations specifically focus on conditions that could lead to a fire. Hence, it is crucial to have a smoke detector in situations where there is a direct risk based on the garage’s connection to the home or its role in harboring combustion sources.
