Cost of adding ~500sft to existing home
Hi, I am based in the bay area and looking to add 500 sft of addition to my home. Nothing fancy, just a hall and a closet/pantry. Convert current hall into a 4th bedroom. What is the per sft price that I can expect to spend for a reasonable quality build? I got someone coming in today saying they will charge 600$/sft. Felt that's insane!
