The 5/8" Type X drywall needs to be between your steps and the house framing. Your framer installed the steps first, and I assume the drywall contractor just worked around it vs removing the steps, applying the drywall, then reinstalling the steps.
Appears you have a breach in your fire rating.
Appreciate you pointing this out. I have zero faith in the drywaller contractor actually removing the steps to apply drywall all around. They drywalled over a central vac port, a light switch, and our sewage cleanout access point. Thankfully, I have hundreds of pre-drywall photos to prove the screwed up and got them to fix all of these.
probably doing it just because . I kind of like that wall there tho. maybe a sheet of ply attached in it's place would give you the "more room you need" & keep a barrier between the stairs & sink.
Interesting idea on adding a thin barrier. I will do that if I don't like the look after removing the wall.
Seems like a lot of work to gain 3" of usable space. Why not just keep the wall but turn the sink 90 degrees? That would get you triple the additional room.
It is a lot of work for such a small gain. The issue is the lack of size of the 2-car portion of my garage and using that space for parking two vehicles. A diagram of what I am working with is below. I have to angle my car in order to create enough space for my wife to get her truck doors open without putting dents in my car which puts me really close to the sink.
The only feasible way to get water lines and drainage to the garage was to put the sink next to the stairs. With the sink set where it is now, I have a five inch gap between the left side of my front bumper and the sink (see the 2nd image). That extra three inches will help reduce my fear of smashing my car into the sink (I have a ball on a string hanging from the ceiling but more space would be nice). I tried turning the sink 90 degrees (3rd image) as you suggested but that only gets me to an eight inch gap. The issue here is the shape of the front bumper and the middle of it sticking out farther than the left side so the space gained is minimal as well. This also creates an issue with squeezing by to get to the sink. The tight fit will be annoying and I am sure I will scrape against the car when trying that.
Also - sorry about the terrible lighting in the photos. Builder only put in three 100-watt light bulbs for a 3-car garage as they thought that would be adequate. Hoping to get some time to upgrade the lighting later this month.
