Basement included in square footage?
I'm looking at a property in Northern California that has a basement. That is unusual for this part of California. Only the ceiling is finished. It is about 20' by 30'. The real estate agent said that you can't count basements in the total square footage. I have a hard time believing that. So if I finish this basement, can I add the square footage to the total for the home? It has an entrance from inside the home, and outside. What do you think?
