Why do people’s houses have certain smells? What causes it?

Question

I’m sure you’ve thought the same question about why people’s houses have a certain smell to them. They’re almost always indescribable other than “It smells sweet” or “it’s an old/new building.” Is there an actual reason for houses having (not unpleasant) smells? How would you describe it?
