ledger attachment


I'm building a covered deck and plan to attach to house using a ledger.
I pulled off a piece of sheathing to show what I'm up against as far as how it was originally built. As you can see, the rim joist is non-existant. The sill plate is 4x8 cedar and the studs are nailed to the sill plate. There's a 1x between the floor joists and the studs.
What is typically done with this? The deck I tore down simply had the ledger nailed through the shingles and sheathing. The only good thing about this is that it came off very easy.
I was thinking of notching out the studs to fit in a dummy rim joist and build the deck as prescribed in the Prescriptive Deck guide. Does that sound reasonable?

#1 Why a ledger?
Make it a free standing deck and the will be 0 chance of the wall rotting out.
That deck needs to be at least 4" minimum below that slider !!!
And siding needs to be a minumium of 6" above the decking or it's going to rot out from the splash back.

I've thought about free standing but, the reason I've decided on ledger attachemnt is because it will be roofed and the roof will be attached to the house as well.

Another Illustration of what I'm thinking if my articulation wasn't clear.

Edit: Slight problem with the illlustration... I forgot the sheathing between the ledger and stud wall.

I came across this thread where this building scenario was answered.
How to attach ledger with no rim joist
Essentially there's no need to notch the studs, just add blocking between.

I would just cut some spacers to fit between the studs and screw the spacers to the 1x8, then use lag screws through the 1x8 and through the sill for your ledger.

I was going to suggest to add blocking between the studs. You may also want to be aware that in order to meet current building codes, you need to install lateral resistance brackets between the ledger and floor joists in at least two locations in the deck.

“FIGURE R507.2.1(2) PLACEMENT OF LAG SCREWS AND BOLTS IN BAND JOISTS

R507.2.2 Alternate deck ledger connections. Deck ledger connections not conforming to Table R507.2 shall be designed in accordance with accepted engineering practice. Girders supporting deck joists shall not be supported on deck ledgers or band joists. Deck ledgers shall not be supported on stone or masonry veneer.

R507.2.3 Deck lateral load connection. The lateral load connection required by Section R507.1 shall be permitted to be in accordance with Figure R507.2.3. Where the lateral load connection is provided in accordance with Figure R507.2.3, hold-down tension devices shall be installed in not less than two locations per deck, and each device shall have an allowable stress design capacity of not less than 1500 pounds (6672 N).”

Excerpt From: International Code Council. “2009 International Residential Code.” ICC.

Sometimes it pays to involve an engineer, he can come up with a great workable option and the building department won't really have much to say since it's engineered.
