GFCI (Ground Fault Circuit Interupter) outlets should be located in kitchens within 6′ of the sink, wet-bar sinks, in bathrooms, roof outlets, garages, unfinished basements or crawlspaces, outdoors, near a pool, or in any other area that may come in contact with moisture.  There are exceptions for inaccessible outlets and those dedicated to appliances (occupying fixed spaces): typically refrigerators in kitchens and garages, freezers in garages, sump pumps and laundry appliances.

Non-GFCI outlets in water source areas are a safety hazard.
