    Default Sheet rocked interior stairway.

    House built in 1981. Stairway under stairs to the 2nd level does not have sheetrock installed for fire protection. Is it required? Closet door separating hallway from area under the stairway.

    Thanks,

    Jim

    Hi Jim,

    Yes, it is required for most stairways. I don't have the code handy, otherwise I would quote it for you.

    under stairs shall have walls, under stair surface and any soffits
    protected on the enclosed side with 1/2-inch (13 mm) gypsum

    If the stair is open below (the underside of the stair is visible), then no protection is needed.

    If the stair is enclosed below, whether it be a non-accessible concealed space or an accessible concealed space (i.e., a closet with a door), then the underside of the stair needs to have protection.

    The reason is that if there is a fire under the stairway, either the occupants need to be able to see the fire (i.e., the area under the stair is not enclosed), or the occupants need to have the stair protected (i.e., they cannot see the fire down there and need time to be able to escape down the stairs before the stairs catch on fire). If the occupants can see the fire under the stairs, they will take some other way out and not go down the stairs.

    Does this apply to a 1981 house?

    A fire is not going to look up and decide if it was allowed to burn or not when the structure was built, it is just going to burn (fires are dumb, stubborn things, they simply do not care about the written word and its rules).

    Since this involves safety I would not be concerned about the code in 1981. I would include it in the report and let someone else decide it is important or not.
