    This is a screenshot from a building code advisory from the city of Regina on mezzanine. In example #2, in room #2, the enclosed mezzanine is indicated as 12% of the open area while 15% of the floor area (of the room). It doesn't make much sense to me, as the way I understand, the percentage of...

    Hi, I am wondering if the bleachers like in the image shown will count towards floor area as I am trying to ensure that the level above can be counted as a mezzanine, therefore it needs to be less than 40% of the total floor area in the Alberta Building Code. Thanks in advance :)
