Receptacle Under The Kitchen Sink?

While looking at a new home purchase, we noticed the garbage disposal, rather than being hardwired, was plugged into a receptacle located in the cabinet under the kitchen sink ??! I was quite surprised to see this. It just didn't seem right. To make this worse, neither the circuit nor the outlet were GFCI protected. Is this a violation of code, or just bad common sense?

Thanks...

This is commonplace and perfectly acceptable, as long as your locality permits it. Often times the dishwasher and the disposal will share a duplex receptacle and one of the individual receptacles is connected to a switch above the sink to operate the disposal.

GFCI protection is not required because the receptacle is not readily accessible and the motor may cause nuisance trips.

Disconnecting means

The cord and plug connection serves as the disconnecting means for the disposal. This allows for the replacement or servicing of the unit without disturbing the home's wiring. It is specifically permitted by the US NEC as quoted below.
