Hi All.
Working with IRC 2012
Please see the code below;
R304.2 Other rooms. Other habitable rooms shall have a floor
area of not less than 70 square feet (6.5 m2).
Exception: Kitchens.
R304.3 Minimum dimensions. Habitable rooms shall not be
less than 7 feet (2134 mm) in any horizontal dimension.
R304.4 Height effect on room area. Portions of a room with a
sloping ceiling measuring less than 5 feet (1524 mm) or a furred
ceiling measuring less than 7 feet (2134 mm) from the finished
floor to the finished ceiling shall not be considered as contributing
to the minimum required habitable area for that room.
R305.1 Minimum height. Habitable space, hallways, bathrooms,
toilet rooms, laundry rooms and portions of basements
containing these spaces shall have a ceiling height of not less
than 7 feet (2134 mm).
1. For rooms with sloped ceilings, at least 50 percent of
the required floor area of the room must have a ceiling
height of at least 7 feet (2134 mm) and no portion of
the required floor area may have a ceiling height of
less than 5 feet (1524 mm).
________________________________________________________
Does this code mean that the "required floor area" under a Cape style (duel slope) ceiling is the area between the 5' ceilings? For example, if I have 12' between 5' ceiling heights then do I need a minimum of an area 6' wide that has a ceiling height of 7'?
Any help with the exact interpretation of this piece of code would be appreciated.
Thanks,
Doug
