All receptacles must be GFCI protected, except ones not readily accessible (such as a ceiling mount receptacle for a garage door opener). Or a single receptacle or a duplex receptacle for two appliances located within dedicated space for each appliance that, in normal use, is not easily moved from one place to another and that is cord-and-plug connected (such as a receptacle behind a fridge).
