Are arc faults required to be installed in garages?

In many residential building codes, arc fault circuit interrupters (AFCIs) are not typically required in garages. This requirement is primarily based on the understanding that garages are considered locations where the risk of arc faults is lower due to the nature of the appliances and tools typically found there.

The rationale behind not requiring AFCIs in garages often stems from the fact that garages usually do not have living spaces and are less frequently occupied compared to other areas of a home, such as bedrooms or living rooms where AFCIs are mandated to enhance electrical safety.

Furthermore, the electrical code may provide exceptions or differences in requirements between detached and attached garages, but in general practice, it is common for garages to not require arc fault protection. This substantial distinction in requirements is why the answer reflects that AFCIs are not mandated in garages under standard building codes.
