Hi,

Looking to build a freestanding deck approximately 20x14’ a little under two feet high.

A lot of the area is covered by large patio pavers that used to be the floor of an enclosed porch.

I was wondering what you guys think about the possibility of just using some Simpson type post brackets directly on these to support the deck beams instead of removing the concrete and digging footers? They seem very solid and I was thinking if I space them about 5 feet apart it may be ok.

The deck will be using double 2x10 as beams (3rows) and 2x8 joists (12”oc) will sit on top of the beams.

I’ll still need some regular footers placed where there is no existing concrete so some of the beams will be anchored to the ground regardless. (I plan planning to use those Titian deck footing anchors that screw into the ground with an impact wrench instead of digging for footings. Iif anyone has good or bad experience with those I’d love to hear before I place the order).

Would have to know your location to venture an opinion.


In my part of the world code allows them to built on top of the ground with no underground support. Up North things are very different.

A lot depends on your local codes. Some may have exceptions for freestanding, low decks that are less than X sq ft... But in most cases you cannot just set a deck on pavers, no.

Unfortunately I’m in The suburbs of NYC (Long Island). I’m not even going to try to get a permit From my town as it is an incredible long process that just frustrates everyone that tries to do anything. That said, still want to make sure it is safe and built above code.

Even if no permit, pavers crack easily enough so aren't good for supporting concentrated weights. Everything diy, I would make min 4" thick concrete (vs masonary mix pavers) blocks.

Put a deck block on top of the paver and plant your post on that.


I did 6 supports like that for my 16x20 deck that's ~36" off the ground. 3 other blocks ended up on existing poured concrete.



I'm up here between the 48 and 49th parallel on the west coast. Frost hasn't done it any harm.

U2 means a few of these: https://www.lowes.com/pd/Common-7-i...5-in-x-10-375-in-Concrete-Deck-Block/50113084


It will hold a 4x4 vertically or any 2x joist.


My deck, 12x18 was built in 1995 using 3 or 4 of them set on compacted clay to support the beam and it has not moved. That is /was to code here. We do not have the freeze heave cycles of the North.
