Mark, your code probably says even more then that. Garage plugs, bath and kitchen plugs within 6' of a sink, spas, pools, etc are all part of the NEC. I used to hate GFI's that would trip in the early morning dew on the construction site. Since then, they have not only gotten better, but now I feel vulnerable without them, and my profession is an electrician. Remember, the GFI will not trip if you simply grab the hot and neutral wire and are not grounded. For example, if you have in one hand, a hot wire, and in the other hand the neutral (not ground), you will at the very least get a tingle and at the worst cardiac arrest. Just to let you know that you can't get lazy when dealing with electricity. Rat...
P.S. the electric power washers can also be a great way to go, I've used a 1.5 hp, but would recommend a 3 hp which means a 240V 30 amp circuit. They are nice and quiet and always start.
