interior door

[careyk]

I have a "restoration" company doing a rebuild after a fire (New Jersey) I have a 3 story townhouse with units along side of me. my question is on codes governing stairway width at top & interror door swings into a hallway/corridor

1) as you walk into my unit there is a stairway going up into unit - at top of stairs what is the minimum maximum width (the space between the handrail & Wall)

2) As you walk in there is a long corridor with a closet a 1/2 bath & a door to basement on the right of this corridor. On the left side is a long kitchen island- My question is on the doors. Is there a code governing the doors. The corridor appears more narrow to me - If the door is open you can NOT fit past it, Im 110lbs - Is there a door "swing" or "projection" code on this issue?


3) Is there a code for width of hallway/corridor?


Thanks
