Hi,

I am replacing my collapsing front porch. I am making it bigger and adding on a deck. I have no building department to ask my questions to. The only approval I needed from the town was for zoning to make sure I am not too close to a sidewalk. Please do not answer my questions with "go ask your building inspector".

I am trying to figure out how many peers and footings I need. I am probably going to use the Sonna tubes.

Foot print will be 12 by 30 with a 18 long 6 wide extension around to the side door.

12x18 of it will be walled, roofed and insulated, to act as kind of a mud room. Leaves 12x12 deck and the little wrap around part.

One side of course is going to be anchored to the house. I will pay to have the footings done, and doing the rest myself, so I'd rather spend a little more on larger lumber instead of more on labor for additional footings.

If I go with 2x10 12 foot long, would I have enough footings parallel to the house if I put them every 10 foot. This would give me 4 posts.

Other thoughts were also 5 footings, spaced every 7.5 foot, and 6 footings, spaced every 6 foot.

I do not mind over building, but I don't' want to way over do it either.

Joists would be 2x10 12 foot 16 on center. Doubled up rim joists, and doubled up where it will switch from mud room to deck.

thoughts?
