I would like to convert my father in laws garage into an apartment. The garage right now is a typical standard one car garage. I would need a full bath and kitchen. I was wondering how much it would cost to install water lines, and drains. Can the water come from the main house? Would it be more expensive to have the bath and kitchen on completely opposite sides of the garage? How much would it cost to hook up to the sewer? I will do most of the other work myself but I know that this is not something just anyone can do! Any info appriciated, thanks!:)
