Hi All, As part of a small deck project I need to construct a decked landing area outside of my back door which will end in stairs that descend to the main deck area. We previously had crumbling concrete block steps that I had taken out when we re-did our driveway recently (see pic attached). The problem is that, because the way the old additions were constructed, the landing would have to be partially constructed on top of a concrete slab. I can run a ledger board on the right hand side under the door, but the other side is just the 2x4 framed wall of the garage. I would like to use anchors to either secure some posts or run something (2 2x12’s?) horizontally, but I can’t seem to find any information on whether this is to. Frost heave obviously isn’t an issue and I believe that the slab is at least 6” thick. The decked section would be fairly small: max area roughly = 10’x4.5’; 2’ or less high. I suspect my building office (NJ) will need to be sold on the idea before they approve my plans – any comments or suggestions (especially references to the IRC) would be helpful. Thanks!
