Outdoor receptacle outlets are required to be installed on both the front and back of a home in order to provide a safe place to plug in an extension cord. This discourages people from running extension cords through doorways (indoors to outdoors) and minimizes excessive lengths of extension cords. The basic rule is that a receptacle outlet needs to be installed where it is readily accessible from grade level, and not more than 6 feet above grade level. This applies to both the front and back of the home. Outdoor receptacles must have GFCI protection, they need to be tamper-resistant (TR), and they also must be weather-resistant (WR).
For many of us, there is no such thing as having too many receptacles in our garages. It seems like we could always have a few more. However, the code is just a minimum set of installation rules.
The basic rule for garage receptacles is that one receptacle outlet needs to be installed in each vehicle bay and not more than 5 feet above the floor. This rule is applicable to both attached garages, and detached garages that are supplied with electric power (a detached garage is not required to be supplied with electric power; that is an option for the owner). The idea of requiring a receptacle outlet in each vehicle bay is to ensure that a receptacle outlet is available for charging any electric vehicles that may be parked in the garage.
