Wink Does deck foundation need footing?

About to build a new deck. When I check this popular site:

http://www.decks.com/articles.aspx?articleid=15

It is asking for a footing. I helped others doing the foundation. never remember we put a footing before pouring down concrete into the 12" cylinder that is 3 feet deep.

The deck is just 4 feet maxumum above the ground.

Any suggestions? Thanks.

The deck needs footings. At 4' above grade, your local bldg. dept. probably requires a permit for it as well. Check with them BEFORE you start. And it'll have to have railings.

How large (in diameter) the footings need to be depends on how far apart the footings are and how you are attaching the deck to the footings. How deep they need to be depends on if frost is an issue where you're building the deck. How far apart the footings are is determined by the size of material that you are using for the beam(s), and the spacing of the beams is determined by the size of joists you'll be using and their spacing.

Thumbs up

Thank you.

I already submitted the permit. they did not say anything about this layout: (obviously overbuilding.)

It will be a 16'x18' deck.

2 rows of beams across the 18' side , parallel to the house.
(7' between the 2 rows)

Beams: 2x10 doubled

3 columns on each row with about 7' in between.

2x8 joists at 16" OC from the house
