The act of performing a cleansing ritual on a home goes back to the 18th & 19th centuries but the practice really goes back to ancient times and used in a very different way. They all however are about creating a sacred space. You may know this practice by its other name "smudging".
All homes new or old have energies associated with them. It may still have the energies of the previous owner and you may want to clear that energy and start over with your family. Not all energies are evil or bad they just aren't relevant in your new home. You may say "well my home is new nobody ever lived there before so why should I smudge?" The answer to that is that everything is energy and all the items collect that energy. The energy of the contractors who work there, the guys at Home Depot who loaded the wood etc.. So why not start out new with positive energy and high vibrations.
