I'm looking at a commercial building (medical) with 2 separate units which I'm assuming is group B. The structure is masonry / wood truss no sprinklers. Each unit has 2 doors front and rear. For drainage purposes, I'm assuming, the rear doors are more then 30" above grade. One unit (a) has basically a deck w/ guardrails with no way to get off it and the other (b) opens onto a board walk w/ guard rail (that needs replacement) that runs down the length of the building back to the front and parking lot. Unit B has an interior emergency exit light at the back door and I didn't get into A due to it being locked. Year built 1991, Zoning commercial specialized.
My question is: Is the rear door in these units also a required fire / egress opening? The landlord has written into the commercial lease my client is supposed to sign that the back door is to remain closed and locked until such time as the landlord repairs / replaces the board walk.
I've spent some time in chapter 10 but its not clear to me...maybe in the fire code?
