The rules for propane tanks on balconies are actually far more obtuse than most people think. You CAN transport propane through the common elements of the building and can use an elevator, but you must be alone in the elevator at the time, there must be a certain distance, etc.. Most condos don't allow them because of height issues (and increases to fire insurance) - there must be a certain amount of distance between you and the person above you, etc.... it all gets really "red tapey" and so in the end people just give the easiest answer. Canadian Tire just had a great sale on the CNE20 electric grill which heats itself to over 500f so you can actually BBQ with it. I think it was only $100 or so.
