I have a 1927 house that is built on a hill such that the basement walks out level with side yard and the sub-basement originally had a door that walked out the back yard with two steps down to ground level
floor above the sub-basement has been lowered such that the ceiling height is only 6'2". The original door and windows were removed and filled with cinder blocks.
I would like to open the door opening back up and put in a short steel door, but it would be substantially less than 6'since there is a substantial threshold and a ledger board at the ceiling.
The other less desirable possibility would be to put a window in the old door opening. Is there code requirements or any other reasons I could not put a very short door in the old opening?
If the door were out-swing, could I just let the top of the door overlap with the ledger board?
Thank you in advance for any advice you have.
