Let there be light.

So in about 30 minutes we are going to be walking through with our contractor to go over all the electrical stuff.  What kind of lights we want, where we want outlets and light switches, and all the other stuff like that. We are hoping to also talk to him about changing the kitchen around.  It will all depend on the down draft for the stove.  Not sure if we HAVE to have one, but if we do there could be an option, it would be tight on one side, but an option.  If we don't have to have it then there is a whole lot more options.  Does anyone know if we have to have a vent for the stove, even an electric stove?  I did a quick google search and from what I read it is not a requirement, but nice to have to get smells out.
