re: Framing House with Rough Cut Lumber

I would not use green lumber to build anything. The odds of you seeing significant movement from the lumber is almost 100%, since it will be under a load and the cull rate on softwood, like pine, is higher than you might imagine to begin with. You probably won't see much movement for months and probably even more than a year.

Also, if there are no building codes in the area, they almost certainly require graded lumber. Not sure about insurance.
