i am interested in seeing what the code is myself. we just remodeled our kitchen and located it inside the sink base cabinet....

I added a dosposer in my former home and put the switch in the base cabnet as well. an electrician told me that was fine to do when adding it after the kitchen was put togther, it always worked well and no one ever turned it on thinking it was a light switch.

There really are no codes to this. If the disposal is plugged in then the disconect rule does not apply and the switch could be in your living room if you wanted it there hah. If the disposal is hardwired then the switch serves as a disconect and it must be under 6'7" from the floor and within sight of the appliance. The switch placement is only based on the common sense of the installer. Switches in cabinets are common and allowed. Also have seen them inside a flip door right below the sink.
