I need a little input for putting storage above my garage. I have a 3 car garage 22x22 with a wall separating a 12'6 x 22 single garage. The joist are 2x8's in the 22x22 garage and 2x6's in the 12'6 garage. Joist run parallel to the length on both garages with the 2x6s spanning the 12'6" distance. I dont think I can do anything with the bigger garage but thought it wouldnt be too hard to beef up the smaller garge with the shorter span. My thought was to sister 2x8s to the 2x6's or get some engineered 2x6's and sister those together so I wouldn't have to remove the strongback. Getting the 2x6's in would be a lot easier. Ok any one have some input?
