Is my deck ledger board secure enough?


W

Wayne

Hi,
I attached my ledger board to my house but I have a concern as to the
fasteners. My local code requires 1/2" x 6" lags, 16" on center, my
house joists are 18" on center. I discovered this after tacking the
ledger to the house an drilling the pilots. The bottom row of lags are
in the sill and fine but half or so of the top row I had to use 1/2"
carriage bolts.
the concern I have is that the carriage bolts that are only in the
sheathing may not be good enough?
I did cut the siding away so the ledger is flat against the house
(should only have shearing force?)

The deck is only 28" off the ground.
Any opinions?

Thanks,
Wayne

In a previous post Wayne says...

Wayne:

If there was no rim joist, then your concerns are justified. This the
kind of problem that is a little difficult to diagnose long distance, so
you might want to consider hiring a local expert to have a look.

In cases like that I ask myself.... " is it going
anywhere"... nahhh. its not going anywhere.. just think what
force it would take to rip out just two of those 6" lags. The
building inspector will not be splitting hairs on that issue
if he even knows the code on it.

It's kind of odd not to have a rim joist across the ends of the
joists.

- Nehmo -
That's right. The ends of the joists just sit on the sill?

The way my house seems to be set up is every 5 feet or so there is a
cement pier on top of the foundation. If you took the house off the
foundation you would have something that looks like a castle wall.
Other than that, the joists just sit on top of the sill.

I have my footings inspection tomorrow so I'll ask the inspector to OK
the Ledger then BEFORE I get everything framed up.

Thanks for all the feed back everyone!
