First before I give my opinion, check with your local building department and see what you can legally build and what permits are required and whether you can use deck piers or if footings will need to be dug.

Welcome to the Forum!

The main factors are the size of the deck and whether it is attached to the dwelling. Also are you located in a frost protected area.

A call to your building official will provide the answer to your question without guessing.

With that said decks installed at or near grade tend to have issues with the joists twisting. This is due to the fact wood absorbs moisture causing it to expand. The top of the joist is exposed to sunlight which causes it to shrink. One side shrinks the other expands. If it were me I'd go with a nice patio, but it is your project.

Good luck!

You might think about updating your profile with basic geographic location.

In some locales, decks not attached to the house are free game and beyond the pervue of you building department. More responsible places do bring them under code and inspection. I am not sure whether you can get away with just simple piers as deck support or not.

Do heed the advice about low decks. 15" to the surface leaves your deck joist structure just 6" from the ground. Why not consider other option like concrete finished by an artisan. Maintenance will be lower than a wood deck and nicely done one can have much more wow factor. Not my fave concrete look but for example to help you explore.
