Questions About Framing A Ground Level Deck


I need to frame a ground level deck. The sliding doors are 6.5" from the ground. Can I frame with 2x6? Is 2 x 6 against code?

Rot city.

Don't know your location, but a wood deck won't breath and won't have a long life.

Forget about composite because most are not rated for that kind of ground clearance. A synthetic board is really the best choice. Make sure whatever wood you put under it is at least .60 treated or better.

Re: Questions About Framing A Ground Level Deck


What about a concrete "patio" instead?

I don't see any way to do wood unless you take out some dirt. I suppose you could use 4x4 PT deck joists at 24" OC, each one supported by piers at 6.5' (I calc'd that). But you're begging for rot trouble. You need more clearance to ensure that gophers and other critters don't pile dirt up against those joists.

Timbertech assured me that the reliaboard would be ok with this minimal clearance. Are 2 x6 against code?

Its all about span for code compliance. In NJ we are allowed 600 sqft with out frost protection but a low deck that can twist with heave is better with beams and footings.

I have done 6x6 beams sunken beams over footings with 2x6 joist over the beam then earthwood planks with no issues. I did maintain a good gravel bed and allowed for vents in the fascias. That was the only way I could keep the platform low.

No particular wood violates code as long as it calcs. You could use cedar poles for joists if you wanted so long as bending, shear, and deflection criteria are met. And also whatever you use must meet the "decay and rot" portions of code which are about adequate ground clearance and / or treatment with preservative.

Will (or have) they assure you in writing? They can suddenly develop amnesia with a warranty claim.

FWIW, my vote goes with Greg Di.

Of course, at home you can take chances. I have a 2x6 framed PT deck set directly on an old flagstone patio outside my back door. It's been a few years so far with no problems. But I wouldn't chance it with a client.

Good Luck
Dave

I am telling you it's NOT OK.

Here's what WILL happen. The deck will look good for a while. The homeowner will undoubtedly neglect the deck and not wash it enough. You will get mildew on the top. Meanwhile, even if you clean the mildew off the top of the boards, the bottom will be riddled with it. Eventually, there will be an issue.

If you must build the deck this low, use PVC, otherwise, don't do it.

Hell, pour a heavily pitched pad funneling water to a perimeter drain.

Use Bisons or tapered sleepers to keep the deck level.

Lack of air is a killer.

Agree with Greg, pour a sloped pad and use Bisons. Use enough of them and you can go with 2 x 4 frame.

Re: Questions About Framing A Ground Level Deck


We might lose some jobs because of it, but it does not make sense to build a deck that low, unless there are circumstances that require it. It's probably much cheaper to go with almost any other paving material, and less worry.

Re: Questions About Framing A Ground Level Deck


I would be leaning toward a patio. Stamped concrete is good, but you could use brick, flagstone, concrete pavers.... It will probably cost more initially, but it will last a lot longer, and maintenance will be minimal.

Synthetic decks still look a little Playschool to me. Even the "good" ones. But, that's not for me to decide.

Right, but this guy's final deck height is on 6.5" off grade. Totally different situation. Looks to me like you might have been lucky enough to get a drop girder under that one. LOL

Fester

There is a big difference between 12-14" and 6 1/2" off of the ground, in my book.
