Our almost completed house is on post & pier and has the 4 corners poured concrete and the rest on pier blocks. My question pertains to the 4 corners and the pony walls(shear walls) under the house do they have to be sheeted with 1/2" plywood or be left open? Of course they have the plywood on the outside already covered by vinyl, it's just the one's under the house I'm not sure of and my plan doesn't say anything about covering them.

Hey Lee, I could not find any reference to the inboard side of your 4 corner shear walls within the county code. From what I've read about UBC codes 1997 states to be sure that the plywood being used is at least a 5 ply 1/2" fir and the nailing detail is very specific along with the correct fasteners (strong-ties) along the path to the subfloor. I thought you used a partial perimeter concrete wall? But I guess what your saying is you used a poured in place footing with a cripple wall the height of your posts. MHO is that if in doubt and no one answers your question I'd add a 5ply sheathing to the inside following a retrofitting guideline. over strengthening a cripple wall shouldn't cause harm. Take a look at this site
www.abag.ca.gov/bayarea/eqmaps/fixit/manual/PT11-Ch-6.PDF it is very goog info and can also be used by others. Hopefully it is helpful

Good morning Lee, I looked over my plans and find nothing that says to add siding to the inside of the pony wall. I'm going to be calling Trojan sometime this AM and will try to remember to ask them. The idea of "over building" with an interior wall may be a good idea but I would be adding some kind of longterm chemical to keep the termites out. I think that would be the last place I would want them "dinning"!
By the way Lee, did you paint any boric solution to the "fresh" cuts while you were building?

Talked to the building inspector this morning and he said if it is not on the plans then it is not necessary but it would add more strength so we will put it on but don't have to have it done for the final. My friend is going to help me with the stairs and railing on Sunday so we very close now. To answer Royall's question we did not put Hi-Bor on cut lumber but we did have the concrete slab for the carport and all the pier blocks sprayed for termites when we started.

My plans call for the plywood inside.

Royall, We are putting HiBor solution on every cut ,as per the lumber manufacturer & HiBor's recommendatio. We cut a milk jug top off leaving the handle for carting around, filled it part way with solution & set it up by our chop off saw, dip the ends into the solution when you cut. (added bonus has been that the few drops left in the jug have become a giant coachroach killer!) After seeing what the termites did to the little bit of lumber (even treated stuff) that was in this house, we are proceding with due diligence. Be forwarned that even pressure treated HiBor wood is not to be left out as this treatment does leech out. In house hunting, we have seen a couple of houses that had a delay in sheathing that do have infestation damage. I don't know how prevelant this is, but once you see the damage these buggers can do, you gain a whole lotta respect for them. Aloha, Carey

Thanks Carey for the Hibor reply. I'm hoping that when our house start to go up the weather holds a little so we don't try to rush things because of the rain. I will get some Hibor and try to get all the ends coated at it goes up.

You probably are OK at that elevation, there is much more rain up at the top of the subdivision.

Hey John, plan to come down when we start the framing. It would be nice to see you again. I would like to introduce you to Jerry, my builder, and see if we can convince him into buying in Hawaii.

If he needs to be convinced then he is brain damaged!
Puna is still very cheap and I expect those low prices to go up much higher.
