Ledger and piers ??
Hi everyone.
I'm starting to design my high level deck. It will be 16ft W by 12ft L by 7ft H.
My question is how to attach the ledger board to the existing wall. that it is brick. what kind of fasteners do I need to use? The basement is already finished.
What is the recommended diameter for the piers? 8 or 12''?
I will use 2x8 for joinst, beams
Post are 6x6
Thanks!!!

Don't use a ledger board. Make it a free standing deck. The posts should continue above the level of the deck & be used as part of the railing. Hang the beams between the posts & the joists between the beams, using joist hangers. I built a second story deck using that design & it survived Hurricane Sandy, in NY.
Use 12" footings, double 2x10s for beams & 2x8s for joists.

Free standing is always a better way to go. Especially since you have a finished basement. Any fasteners you use for an attached deck, must not only penetrate the lumber, but must go through the brick and penetrate the frame banding of the house. Here's some reading for your deck knowledge. Ask away, we're here. http://www.awc.org/publications/DCA/DCA6/DCA6-12.pdf

Hi, thanks all for your response. I was initially not thinking in free standing deck because I am not sure if the holes close to the house can affect the foundation.
How deep the holes should be? (the hole has to be 4 feet deep? I was initially calculating 4 feet for the other holes)
How far can I dig the holes from the home?
Thanks in advance..

The foundation shouldn't be affected. The depth of the holes depends, on the frost line. The center of the holes near the house can be about a foot way. How far away from the neighbor's deck will yours be?

Thanks Pulpo!!. I live in a townhouse, so from the neighbor's I have no more than 3 ft between windows.
In the photo you can see the neighbor's deck is almost inside my living room

Any footings you have will need to be cored through your patio to a depth that meets local frost line requirements. In addition:
"DECK FOOTINGS CLOSER THAN 5'--TO AN EXTERIOR HOUSE FOUNDATION WALL MUST BEAR AT THE SAME ELEVATION AS THE FOOTING OF THE HOUSE FOUNDATION." Section 10
So free standing deck footings must be at the same level within 5'.
Section 15 prohibits deck attachment to or through a brick veneer.
