Can you use it for constructions?

I used an Alaskan Sawmill to mill 6x6, 4x12 out of white oak. I used them on our 16 x 20 pavilion.
Had I had the sawmill earlier, I would have milled the beams for the cabin build.

So i guess the question is can you legally use it to build habitable construction.

Depends on whether or not the building authority wants to see a grading stamp on the lumber. The AHJ may also be happy with doing a visual inspection to see if the stock looks to be good enough for where it is used. What you get from the sawyer will depend a lot on the sawyer's knowledge and integrity.
Not every stick that is milled can pass to be grade #2 which is the usual normal construction grade. The main place to watch for knots that are too plentiful, too large, too loose, or too close to the edge is for joists or beams. Stud grade is lower than #2.

My friend in oregon, where code requires a stamp, hired a guy to come and grade his lumber. He estimated about 60% of the lumber got a grade and the other 40% was not gradable.
The stamper charged 450/half day of work, with the half day being the minimum. So if it takes 2 hours, you get a half day bill. If it takes 6 hours, you get a full day bill...etc.
Those extra expenses, waste and grading, just about evorpated the savings on the milled lumber.

In a mill those ungradable get to be utility grade, pallets, or whatever.
FWIW, the highest paid worker in a mill is the grader.
And also, FYI, it is easy to turn a grade #2 2x6 or 8 into two utility grade pieces simply by ripping it. Depends where the knots and other flaws are located.

He had to go back and cut the 40% plus another margin of 40% that will get rejected. Then he has to pay the guy again to come and grade it, not to mention his time and expenses.
If your county requires a grade stamp...it's cheaper just to pay for already graded, planed, dried lumber at a store.
Considering he rejected 40%, imagine all the lumber being used that is not of great quality. Scary.
Like the old saying goes...it's too expensive to be cheap.

A friend was a grader in a mill in Oregon many years ago. He showed us how he would look at the 2" thick slabs as sawn off the logs and make decisions on what widths and where to cut a long sawn slab to different lengths. Cutting out a knot and discarding it can result in two pieces of a better grade. Lots of variables and there are many small sawyers who know too little about grading, or don't care, maybe even don't believe. All in a matter of seconds. Now computers do a lot of the grading
