Deck construction support
Hello - I am in the process of designing a deck for my house. As I have a walk out basement and want the deck off the main floor, the deck will be one story above grade. The back of my house has a 3 season porch protruding out about 12 feet. My idea is to have the deck also protruding out from the house, next to the porch. I know I will need a ledger board on the back of the house, and a number of posts on the fasr end of the deck supporting the weight there. My question is, do I also need to connect the side of the deck to the porch in any way? Basically, I am getting at the folowing:
| |
| house |
-------------------------| |-----|
X| |
deck here X| Porch |
X| |
X----------------
Do I need to connect the deck to the porch where the Xs are?
Thanks!
