A strict list of domestic requirements awaits the teams on the lawn of the National Mall. Each house will be responsible for washing and drying twelve towels for two days; cooking and serving three meals a day, then washing the dishes after each meal for four days; and finally, running a TV/video player for up to six hours and a computer for up to eight hours for a total of five days. The judges rank the teams through calculations that rate the efficiency and completion of each task.
