Re: Jack studs, Lot 13, Estates at Clay West Dear Mr. Moet: Following our meeting at this new homc under construction this morning, I have researched the issue of the need for multiple jack studs underthe hcaders ofthe large doors and windows on Ihe first floor and in the basement All of/he opening.' have 2 x 12 headers that are supported by single jack sluds on each end. Tablc RS02.5 (]) shows the requirements for headers and jack studs for cxterior 1Nalls. A copy of the table is attached. In the greal room on the first floor, there are 4-foot openings in a wall that supports a cathedral ceiling and roof. U11dcmeath the great room are similar openings in the basemcnt According to the Code, those opcnings could have used 2 x 6 headers with single jack studs; SO these window openings meet code. In the nook, there is a 6-1'001 opening in the back wall that supports the floor above, and a 7- foot- 4-inch opcning in the side wall that does not support the floor above. In the basement bdow the nook, there is a door in Ihc side wall with a 6-foot- 4-ineh openi.ng. According to Ihe Code, the 6-1'001 opening in the back wall should have two jack studs, but since thc span of the joists above is only 11 feet and 4 inches, I believe that the single jack stud is acceptable. In the library and dining room, there arc 7-1'001- 4-ineh openings for windows in walls that support thc floors above that have IS-foot spans. With those combinations of faclors, [can not interpret the Code as allowing single jack studs. [ believe they need doubles. In the master bedroom, there is a [O-foor- 6-ineh, 3-ply L VL across an opening supporting the roof above that has a 20-fool span. As 1 intetprel dle Code, that could have been framed with 3,2 x lO's with single jack studs; so that I believe that is within dle Code requiremenL'. Richard 0 Albright, Inc., dba RLchard 0 AlhrlghL. P.E. Nov 04 05 12:11p HRQuest 317-581-8856 p.2 ,/ November 4,2005 . Page 2 In my opinion the window openings in the back wall of the nook, in the lihrary, and in the dining room should have douhle jack studs. The other openings are satisfactory.
