When Andrew began doing more residential home inspections than commercial building inspections, he found that his knowledge transferred well when he inspected residential structures that had formerly served some sort of commercial purpose, such as an old factory that had been converted into an apartment building. He had a lot to learn, however, when inspecting residential structures that had been built as homes from the beginning. What is the most likely factor contributing to Andrew’s existing knowledge of building inspection?


whether the structure has served different purposes

how old the structure is

whether the structure has ever served a commercial purpose

how large the structure is
