Yes, all 125-volt, single phase, 15- or 20-amp receptacles in a garage must be GFCI-protected, with only one esoteric exclusion that we will cover later. But it wasn’t always this way. Up until the 2008 edition of the NEC (National Electrical Code), there were two exceptions allowed for the GFCI requirement at garage receptacles:
1) Receptacles that were not readily accessible, such as a ceiling receptacle for a garage door opener.
2) A single receptacle that served one appliance or a duplex receptacle serving two appliances, which was on a dedicated circuit and “located within a dedicated space for each appliance that, in normal use, is not easily moved.” Typical examples were a water softener, sprinkler control panel, washing machine, freezer, or refrigerator.
The 2008 NEC wiped out these exceptions, and now only exempts “receptacles that are not readily accessible AND are supplied by a dedicated branch circuit for electric snow-melting or deicing equipment” that is permanently installed.
