Leave the ridge in place and rip the bottom if it extends down below the underside of the rafters. Your ridge beam can be tucked up tight to the underside of your rafters. Use some strap ties to connect the rafters to the new ridge. You will need posts at each end of the new ridge beam. At 24'...
When choosing 16" vs 24" oc, its not just about insulation. You must also consider the wall sheathing. At 16" you can use 1/2" plywood or osb. At 24 you should go to 5/8" thick material.
Then 5/8" sheathing thickness messes with window and door jamb depths.

I was referring to your diagram showing vertical studs located at the intersection of the 8' high ceiling joists and the 12:12 pitch roof rafters. If you do that without a "slip-clip", the studs become load bearing and then transfer loads to the floor...
I built a garage with a very similar section to yours (minus the lean-to). Your 12:12 pitch should carry completely on the header in the exterior wall and transfer no loads, zero, nada, nothing, zilch to the floor joist framing. You show a wall or stud in your diagram.
I tripled up my rafters...
As others have said, I would not attach to the bottom chord of the existing trusses. Trusses in "pole barns" are designed to the bare minimums. Often the bottom chords are designed for dead loads only and zero live loads.
If those 2 - 1 3/4" x 14" lvls were working by themselves and spanning...
Thanks to all who have thrown out the welcome mat. I have updated (slightly) my profile and will add some photos when I get a chance.
Any of you folks needing any help with the design of your garage...let me know.
Hello All -
I'm just a guy like all of you who like garages and all the stuff you can do with them. My favorite building type for sure, especially when people get creative and use them for more than just parking a car or two.
I think I will lurk awhile. Hopefully later I will post a few photos...
I have petitioned for variances many, many times and was unsuccessful only once. Here is a little background and maybe how I would approach things. All info is based on how it is generally done in the suburbs of Chicago.
You are seeking a variance from a Zoning Code. Make sure you have read it...
