RE: 624 square foot northern Michigan lakeside cottage
There are two (2) existing exterior doors to this small cottage. One faces the deck and lake, and the other faces the road and is located in the tiny kitchen.
I would benefit from sealing off this kitchen door and including that space in the expanded kitchen. Are a minimum of two doors required in any dwelling (again, this is a small cottage)? Or are numbers of doors related to square footage - this is 625 square feet.
Wondering if there is some sort of fire regulation addressing this. At any place in the cottage, you are no more than 20' from the lakeside door.
