We are having a deck and porch installed as part of an addition to our house. The deck and porch combined are about 32′ x 18′.
The architect and structural engineer have recommended that the deck and porch be supported by a set of sonotube footings of various sizes. Some of these footings are two feet from the foundation wall on the house. The deck and porch attached to the foundation wall by means of a ledger board, with the ledger board being fixed to the masonry foundation wall either by means of sleeve anchors or through-bolts.
The roof over the porch and house is not supported by the deck and porch sonotube footings, but rather by 16″ x 16″ masonry pier footings which are about 8′ to 12′ feet away from the foundation wall.
Our contractor would prefer to get rid of some of the deck and porch footings and have more of the deck and porch load carried by the house foundation. He is particularly concerned about having some deck and porch footings only a couple of feet from the foundation wall.
Is one method preferable over the other? We are interested in your recommendations and experiences.
