Heres an update pic... id be done if it wasnt for all the dang overtime
I hate to put it this way, but a lot of that 'depends on the loading' of your counter.
However if you have L brackets like the picture that are about the full dept of the overhang, 4 of them on a 4 foot wall should be sufficent. I might get some smaller ones and put them on the other side to improve rigidity. - but then I'm from the 'when in doubt over build' school
Cut it. Go to the next full joist in either direction of the opening and double it up (either side of the joist, whichever is convenient). Cut the joist out and then box it in with 2 more members per side. Here's how it should look. You may have more than one cut joist in the opening, I only drew one.
Grey - Walls
Green - Existing joists
Red - New framing
Blue - Optional blocking to make the opening the size you want. May need to double up if trimming the hole with moulding wider than 1.5"
The rof slopes down right there but there is room to crawl up and opens wide once your upIn the photo, it looks like the rafter above the fan does not leave much headroom. Do you know if there is enough headroom there to meet your fire code?
So the existing joist only need to be doubled up the width of the hallway correct?, not he full length of the joist?
