    A 2012 Virginia Residential Code amendment requires an accessible route when certain conditions are met. One of those if the hallway is wide enough to allow for a 34-inch door or case opening. How wide would the finished hallway need to be?

    Thanks in advance for your answers.

    R311.2.1 Interior passage.

    . . . . Any doors or cased openings along such interior passage route

    providing access to the areas identified above shall comply

    with the following.

    1. Cased openings shall provide a minimum 34-inch

    clear width.

    2. Doors shall be, at a minimum, nominal 34-inch

    doors.

    Exceptions:

    1. Where a door or cased opening, and its associated

    molding or trim, is at the end and facing the

    length of a hallway and the width of the hallway

    is not wide enough to accommodate such doors

    or cased openings.

    A stock split-jamb prehung door would take 3" each side, for a 40" width.

    In theory, you could get a 34" door in a 36" wide hallway, but it would require a custom frame.

    I won't go into details of how I feel about this amendment.

    Rough frame opening on a jambed door is 2" over call size. That's typical. So a 2'10" door will flush frame in a 36" framed hall. Your header will call out 5" over the door call size.

    So you put the trimmers in flush with the framing, and the header has blind kingstuds behind it, so you are building a channel with the flat part as the trimmer, the kingstud then sits behind that.
