Attaching ledger board...

Good day all. I'm new here

I will be installing a deck this summer and was reading about ledger boards this morning. I was lucky enough to find a picture I took a while back without the siding showing how the house was built, exposing the rim joist:

Is it me or it looks like plywood or pressed wood?
The floor is framed with I-joists...

Any advice? Should I use lag bolts?

I will be framing in 2"x10".

PS: Sorry for posting a link to the photo. Uploading here didn't work :\

I'm always traveling thru and looking for sticky points.
This will help too in the future... http://www.doityourself.com/forum/electrical-ac-dc/534445-how-insert-pictures.html

Can't help you much with your ledger attachment to flakeboard there.... not much strength.

Your ledger is most likely LVL (Laminated veneer lumber) which is produced as a very strong product. It is not simply OSB. Ideally you will use carriage bolts through your deck ledger, and the house band, secured on the inside with washer and bolt. Note, if you use a 1/2" carriage bolt, you should use a 3/4" washer on the head side as well to prevent pull through. However lag bolts with washers are acceptable. See figure 14 in the light reading below

Thanks. Anyway I can know for sure what it is?
I don't have access to the inside of the house. The basement's ceiling is closed...

The band is there. It would not be a single sheet of OSB. Even if it were not LVL, there is dimension lumber running along that band. I am not sure why you need to know more than is necessary. Are you putting up a deck? Use the information in the PDF I referred you to, or ask questions here.

Since you don't have access, the use of lag bolts is adequate as per Figure 14 in the PDF.

My 2 would be to skip the ledger board and build a free standing deck instead. Why punch a hole in a perfectly good wall which is keeping all of the elements outside like it's supposed to be doing?

Thanks. When I go get my building permit, I'll ask the clerk and/or inspector.
It may be different in Canada.

Thanks for the input. For some reason, I always thought free standing decks were less solid. Especially if it's 5 feet high...

The only problem I see with a free standing deck is the posts next to the house must be on footers as deep as the house footing......big hole. I agree with free standing not allowing water to infiltrate an otherwise non leaking wall, BUT if it is built correctly and flashed properly, water can be diverted and the deck will be more solid. With a free standing deck, you would brace and cross brace all the vertical and horizontal members and it would be rock.
