I somehow deleted the bottom 1/2 of the post I started above. I wanted to also say:
The restaurant range in my house puts out a lot of heat when fired up. The walls will get hot to the touch. The six pilot lights also put out a lot of heat on their own, and probably cause my a/c to run a little extra in the summer. The knobs do not include the "push to turn" safety feature common to residential ranges. Kids would have to be supervised carefully around this range.
All in all the range makes cooking fun. It was a nice compromise as it was much less expensive than a comparable Viking or DCS residential range. In my experience, a restaurant range has proven practical for home use, and I am not aware of any local codes regulating stoves. YMMV.
