Dear Kurt,
Per your request I have reviewed the framing conditions of the rear baserryent wall of the home referenced
above. The purpose of my review was to determine the acceptability of the Installed size and spacing of
the wall studs )
,
It is my understanding that the walkout portion of the rear basement wall)s framed with 2x4'5 at 16" o.c.
and the partial-height concrete/framed wall has 2x4's at 16" o.c. atop the/oundation wall (approximately 5'
in height) with an additional wall of 2)(4's at 16" o,c, framed directly inside,the foundation wall.
,
The municipal inspector cited IRe Table R602.3(5) in determining the fra~ing to be in violation of the code.
Table R602,3(5) does not specifically allow for 2)(4 stud framing to be 'used In basement wall framing
supporting two floors and a roof. In my opinion, this Is due to the fact thallhe'code in general and this table
specifically, were wrttten to apply to many generallayouls and condlllons. It does not indicate, for instance,
the depth of the building or the span of the joists and rafters that provide load to the wails.
My analysis of the studs included the co.de required roof, second and first floor live loads as well as a
conservative estimate of the bUilding dead loads. Also included in the analysis was the code required
!ateral wind pressure.
[ have evaluated the stud requirements and found that double-2x4 studs at 16 inches on center are
adequate, in this case Therefore, the atuds in thll full-height framed wall should be doubled for adequate
support The partial-height stud wall with the additional 2)(4 framed wall is acceptable because ils
construction is fundamentally equivalent to double studs spaced at 16' O.c,
Please contact me with any further questions or comments.
My opinion, stated herein, is IImhed to those issues discussed. Other issues regarding the construction, if
any, are beyond the scope of this letter. .
