Sorry for my poor drawing skills, but i havent figured how to use a proper design program.

Is this roughly the proper way to frame the joists on a wrap around deck with a 45 corner and not a 90 ? . I havent done a corner like this before where the stairs will be located.. thanks.

Looks good to me....are you mitering your boards in the center of the stairs, or both sides? some people like having the boards parallel to the rim all the way around. In that case you would hang the cripple joists off the last common like a hip/valley.

i love these wrap around stairs, but depending on the height of the deck the stair becomes 50+% of the deck which is a bad thing
better deck i did
what makes these wraps sweet is the continus flowing rail there is a calculation for it, if anyone knows can you please post. i have done this style 3 times and forgot all times

Thank for god for MS paint or else I would be scanning my graph pad :blink:

Just straight down stairs on that 45 portion of the deck to the drivewave/yard. Correct decking will 45 around the corner also so its parallell with the stairs

Where the yellow lines are are you suggesting i run a strip of decking there like that so the mitred angles don't have to butt up?

I would change the framing so the joists are perpendicular to the stairs. IMO when framing for a deck I try to frame for the neatest nailing pattern.

Loneframer is exactly right, your boards won't match up, but if you miter in the middle, you still have long angles running at the rim joist.....It's all a matter of preference.

one more option..... you could widen the 'hip' angle (of the deck boards not the framing) to correctly bisect the angles..... the nailing pattern gets screwy without additional blocking, takes longer to lay out, and adds some complicated cuts.

The problem I see with the OPs drawing is that by framing the deck in that manner, the miters can't be aligned using full width boards on the angled portion of the deck. On a 5.5" deck board, the 45 degree miter will have a diagonal of just over 7.77"

One option would be to rip the decking on the 45 degree section to 3.89" giving the miter angle of the narrow boards a length of 5.5". Framing would need to be tightened up on centers and perpendicular to decking.

Another option would be to picture frame the perimeter and run the decking into the perimeter board and miter into the "hip" joist at that intersection.

Mark how is that 4x4 attached to the house? Is it resting on that corner board, I cant quite see that.
Heck if I know. I just found the pic in my collection.:whistling

Normally we would notch it to fit the ledgers on each side and either bolt through or lag into the ledger and house rim. In this case it looks like a downspout is in the way, so we must have lagged it on one side only. I think that it is a 6x6, by the way.

Thanks for asking:no:

Is there one step down from the top left section of the drawing? i wouldn't put the strips where the yellow lines are. I think someone said to put a strip down the center( where the center of the stairs is, but up on the deck) I'm not sure i'd like to see all those cut edges along the deck stairs but not much else you can do.

good luck and post some pics when you get it framed.
