Hey Woody.
Chiming in here again as Deluks has raised this thread on my behalf as he will be on top of the ladder in this project, so to speak.
The wall is wobbly because the entire garage was originally a carport, which the owners enclosed at some point some time ago by building up with cement blocks.
The long wall opposite the main house has been tied into the original carport posts, so with the existing joists running back to the house, that assembly is sturdy.
With the main double garage doors occupying 90% of the span on the one end, it is the short wall at the back of the garage that is the focus here, as it is built up to the UNDERSIDE of the joists and spans about 80% of the width of the garage, the balance of the span being a single door with no lintel (or similar) tying it into the long opposite wall - so almost free standing as such.
Addressing this "wobbly wall" is purely a common sense type of requirement as it will never be touched, bumped or pushed once the inner shell has been built (this inner shell is an entirely seperate concern and place for discussion/debate - but for the sake of creating a logical picture, it will ultimately be the same as erecting a timber shed inside the garage, so not touching ANY part of the exisiting garage besides the floorslab, with a 4" gap all the way around between this inner shell structure and the exisiting garage walls).
I have permission from the landlord to put up a more substantial roof structure (OSB and Felt) in place of the plastic sheets that are cracked and riddled with holes etc - and it just makes sense not to be giving a structurally unsound end wall a wide berth whilst doing any of the work.
Landlord gets a better roof for free and I get to keep rent down by not trying to engage landlord in any of the issues that arise.
@posters who may be fed up with my "annoyance" in previous post - no arrogance intended - just that not every story has to fit into the same cover and there are vast areas of exceptions to the rule.
Peace.
