Handy man, you are correct. I planned on adding 2x8 rafter ties. So I could NOT add the ties above that 4 ft. line? The door will come into the space near the point where the vaulted ceiling will flatten out.
The problem is that if I put in a regular (6'8") door, when you open it, you could be staring at 3-4 inches of ceiling. If I raise the ties, I get outside of that 1/3 rule.
My option are to shorten the door (not sure inspector would approve of that)
Lower the ties so they are exactly at 80", keeping most of the tie in the lower 1/3 but also having a portion in the upper 2/3 (if that makes sense). Also, not sure if inspector would like that option either. Any idea of that would still suffice?
