Total height of low level ground level deck
I am building a 10'x12'deck (not attached to a ledger board). My plan was to pour concrete footings, then run doubled up 2"x8" beams setting on the footings with simpson strong ties brackets, and then have 2"x8" joists setting on the beams. Basically, I have about 15" to 17" from ground level to top of decking.
The total height is too high from top of decking to ground level for my doorway. I don't want to dig down and make the concrete footings below the ground level.
Option 1: Go with 3 rows of doubled up 2"x8" beams (3 footings each row) and then run 2"x6" joists with hanger brackets 16" on center. This option may still be a bit high over all.
Option 2: Same as Option 1 except use "2x6" beams so I can increase concrete footing height up out of ground.
Which of these is an acceptable plan for compensation of height? What other options should I consider?
To save the most height the 2x6 beam with 2x6 joist hangers is best. Keep in mind that most code officials generally frown upon 2x6s as joists but for a small project it should be fine.
Also, full disclosure as I would also point you to a product I invented called the Titan Deck Foot Anchor which works very well for setting beams as low as 2" above grade. You can two 2x beams in a 4x4 saddle or three 2x beams in 6x6 post saddle. Then use joist hangers to set joists flush with the top of the beams.
This gives you a very low profile deck. But I would recommend that you download me Ultimate Deck Foot Anchor Eguide
to see all the illustrations and tips laid out.
