Overlap Wall Sections with Sheathing

[vtjon]

I am building my garage wall in sections. They are being built on the floor including sheathing then stood up. My first wall is 16' long. It will have a double bottom plate and a double top plate. The sheathing will be attached to both.

Do I need to overlap my wall sections with the OSB sheathing? I have 3 rows of sheathing. The bottom row is 2 8' pieces, the second row is a 4'-8'-8' (or 4' depending on the answer), the third row is 8'-8'. My next section will be another 16' wall.

While I understand the advantages overlaping the sheathing between walls, the 4' piece hanging over the middle of the row will effectively create a sail on my first wall while I wait to build the next section. It could be a week or more before I get the next section up. It also make it hard to put the housewrap on the section.

Thoughts?

That’s a big wall to stand up fully sheathed. Do you have a machine?

I’m not sure in code but yes it should overlap so it helps tie both walls together. The whole wall will be a sail so just brace it well.
I found the overlap on the bottom row helps guide the next wall in place. I am not an awesome framer so I only sheathed the bottom of the next wall and some of the next row if it did not overlap. I kept mine so one row overlapped four feet and the next had no overlap. Trying to raise a 16 foot puzzle piece required a little trimming for me so I just sheathed after it was up. Harder yes but it goes quick

Your second top plate should overlap the joints in your first top plate as well.

I've stood 30'+ walls fully sheeted but I had a crew of 4 including myself to do it. if you have a pair of wall jacks you can do the whole thing in one piece wit some extra hands to throw the braces on once its in place. now to answer your question although it may have some benefit to overlap the sheeting its not a requirement. up here in Canada its common practise to frame and sheet the walls on the ground before standing. as mentioned previously overlap the top plates to tie the walls in together and overlap the corners with sheeting to tie the corners together as well. even if there is a **** joint once the walls are up and you string the top plates to brace and remove the crowns in top plates you will be fine.
hell if you want to get adventurous tyvek the wall while its laying down as well.
