I am thinking of installing some posts under the deck, along the deck edge where it connects to the side of the house. Then I will literally cut away the deck from the house, leaving an open space between the house and deck for the leaves and water to go. Does this present any problems, and will a permit have to be pulled for this?
Do you need a permit for this? I would say so, check with your local building dept.
However, I don't see this as a feasible plan, as it would not be as simple as "cutting the deck away".
The issues of water penetration lie with the way the deck was attached to your home, the flashing ,the pitch, the weather sealing, the drainage, etc. What about your roof - gutters above that area? Is the deck properly pitched away? Is there a door near it that could be allowing moisture to enter?
There are other factors to look at.
I would not suggest to anyone, to simply "cut a deck away" - supports under it, or not - as a plan to stop water penetration.
IMHO: All you would really be doing would potentially be allowing a pathway for more water to enter your home.
If you feel you need someone to come in and look at this issue, contact some local contractors to look at the area and give you some "free" evaluations about how the water is getting in and what should be done to correct it. You could also bounce off of them, your "cutting the deck away from the house" to "stop the water infiltration idea" and see what they say. Tho, don't be surprised with the responses.
