if I record 10 shops in a strip mall buildings. They leave a distinct trace in older buildings. using the Shop area, what is it that tells someone that they are all the same building?

It is possible to see the interior walls on the roofs of strip mall buildings. They leave a distinct trace in older buildings. My question is if I record 10 shops on in a strip mall using the map, Shop area, what is it that tells someone that they are all the same building. Should I put them inside a building polygon? How will it differ from adjoining buildings with shops in each one? Is it more accurate to use points?
