Hi, Welcome to JustAnswer.com, I am glad you are here! My name isXXXXX built 200 sf. in Dillard GA and were not required to pull a permit. I am going to refer you to a great Forum called "Small Cabin Forum" that has a lot to say about exactly what it is that you desire to do.
I realize that I have not answered your question directly however, so do not feel obligated to accept my answer unless the information or link I have provided actually turns out to be of some help to you!
Hello, and thanks for your question! My name is XXXXX XXXXX I am happy to assist you today!!
Here is the problem your going to face.
#1, is this on private property where nobody can get to it and sleep?
#2, Are you going to invite people over to use it or just you and your familly?
On a structure that large, yes they probably will because its big enough that if it fell it would hurt or kill anybody it landed on. If your out in the sticks (I can say that because Im from louisiana) and have no building department to just "check"things out, then most times they dont have a problem with a person building a shed to keep things in on a temporary basis. I have built several and can tell you that it will greatly depend on the area you live in.
But if your out far enough away that your hunting then your probably not going to have anybody just drop by to look unless you have a person that turns it in .

Charles ps. What and where do you hunt?
Very good, I have 10 acres in la in the middle of the woods. Love the deer! never could have a garden though! the things breed faster than rabbits now, lol
I would use 2x10s running in the 12ft length minimum if its flat with snow loading if you get snow. If you do get snow then 16" centers and minimum 5/8" sheeting. Im not sure if you get snow at that location, but as an engineering contractor I tend to overkill because of unforseen issues. If you get snow and have the roof pitched at at least a 5/12 pitch then you could do 2x8s at 16oc.
If the area get minimal snow if any, then 2x8 flat roof is ok with 5/8sheeting and 24oc. I would be sure to give the roof at least a 3 to 4 inch drop thiugh for drainage.
2x4 walls are fine at 16oc.
6x6 in the corners and in 2 more in the middle on simpson post anchors in18x18x18 footings if the soil is stable. If not then 24x24x24 this way you dont have to worry about it when your not there. Do not direct bury the wood in concrete, they dont like that.
The floor joist, 2x8 at 24oc is ok if you use 3/4" t&g sheeting with suport beam running down the middle.
Thats how I would start.
Is there a house on the property now?
