   not sure what you are saying...are you ADDing another 5 feet? Are you speaking of an interior wall, exterior corner?

   If it is an interior wall and you want to add aperendicular wall to it you would use a Stud "T" method.  In an exterior wall you have al sort of obstacles including roof lines.

   Hello. Sorry if i'm not clear. This is a exterior wall (through wall) and is load bearing. This is an addition to my home. Lets see if this helps, if I want to extend the length of my home by 20' how would I tie into the exterior walls without being able to lap the top plates since there is a roof on the house already?

    

   Thanks

   Simpson makes a tie plate that satisfies the tie-in requirements for bearing walls. We often use them liberally instead of the old lap system. I think the codes required 4 nails in each wall where I framed. The simpson plates had holes for a dozen in each side of the joint but overnailing is as bad as undernailing.

   Thanks Jim. If I understand correctly I would have to lap the top plate by 4' since it is a broken wall. Is this correct? Is that what a broken wall means? When both plates are not continuos?

   Thanks Again.

   The codes are funny in that they recognize the need to lap the second plate by 4' to provide "better" construction. It makes sense. The ironic thing is that they will allow a plumber to chop BOTH plates out and add a tiny metal plate to "mend" the plates. I can't adequately comment on your exact situation without a plan view. Sometimes, even if you meet code, you still aren't going to be happy with the results. Common sense has to prevail.Can you post a simple diagram? Bob's next test date: 12/10/07

   Thanks Jim for your help. I drew up something simple using "Paint".  I can scan the actual print when I get home and post it.

   In order for me to do it by "code" I would have to remove some of the roof and rafters in order to be able to overlap the old exterior wall top plate with the new exterior wall top plate.

   If I use ties I would assume that I would need to use one on the outside, inside, and top of the plate to tie the old/new wall together. Do they make a "cap" that would go over the old/new plates that would tie them together?

   Nope.You'd only have to put one mending plate on the inside face to meet the code. Remember, it's would be stronger than a hole cut by the plumbers for a vent stack...so don't fret. You also will nail the studs tight together and if you want, put three more plates on them. Bob's next test date: 12/10/07
