I want to build a free-standing deck (no ledger board) which is only about 6 inch over the ground. The deck size is 22 X 14. After that I'm planning to put a metal permanent patio cover (20 X 14 x 10) with fiber panels on top . The metal construction of the patio cover will be attached directly to the wooden deck. The local code for the deck is 8 inch wide and at least 36 inch deep for the footings.
My questions are:
Do I need to do the concrete footings required by the code to install free standing ground deck?
Do I need to do the concrete footings for an extra support for the deck since the patio cover will be installed on top of the deck?
