Bought A House From A Company That Was "renovated." They Broke Codes And There Are Numerous Safety Violations.

Location: Detroit, MI

So as you may know, a lot of investment companies have been renovating homes in Detroit now that the city is rising from the ashes. Unfortunately, the company that renovated this home before I bought it apparently did the renovation under the radar. It's clear they didn't pull any permits to ensure the work was done correctly, and seems the crew that did the work had no knowledge or skill on how to properly renovate a home. The major issues I'm seeing weren't caught on the inspection (I'll explain why), and I'm looking at essentially needing to renovate the entire home myself just to fix the problems, probably costing me well over $100k. I already paid a premium on this house, much higher than others in this area, because the renovation looked great at first glance. Essentially I'm at a major loss on what to do... If there even is anything I can do. Here are some of the issues:

1) We started having trouble with some of the recessed lights shorting out. I hired an electrician to investigate and discovered that those lights were not wired properly. They have these boxes you need to run the wires into through grommets on the side, but they instead just wired them through the part you can open and pinched it shut on the wires. Not only that, but the lights were wired with 16 gauge lamp cord which is a major code violation. More issues started happening upstairs, so we ended up deciding to vacuum out the attic insulation to be able to see all the wiring and replace any issues (this is why this wasn't noticed on inspection - the wiring was hidden underneath the blown in insulation which is normal). Turns out they used lamp cord to run all the lights and everything was installed improperly which caused shorts and electrical hazards. We started replacing wiring which required us to start replacing wiring going into the rooms below. Come to find out they used lamp cord to connect the outlets and switches, which is incredibly dangerous since lamp cord can't handle much power load that an outlet should be able to handle. Turns out this was done all throughout the 2,400 sq ft home. I was told the entire home would need to be rewired. I got multiple opinions which also confirmed this (although that should have been obvious with the circumstances). Multiple quotes ranged from $16-20k to rewire the home. That's not including all the extra cost with needing to redo or patch drywall through the entire home and repainting ($7-20k quotes depending on how bad they need to tear up the walls). They also mudded over the junction boxes with live wiring inside them instead of leaving them accessible (huge code violation). We only discovered this because it looks like a smooth ceiling from inside the room, but found the junction boxes up in the attic. We had to cut them out from above and go back into the room to chisel out the drywall and mud that was packed into the live wires.

2) The tub in the bathroom was draining incredibly slow. The inspector stated it was probably full of construction dust/minor debris, since there was drywall dust in the tub. Makes sense. Anyways I later got around to trying to unclog the tub. When I removed the drain cap I discovered the tub wasn't even hooked up to a drain properly. Looks like the plumbing underneath wasn't installed far enough out (the actual drain in the floor is almost 2 inches to the right), so instead if fixing the issue they installed the tub anyways and chiseled out the gasket to allow water to overflow through that tiny gap and eventually make its way into the drain. I haven't pulled out the entire tub, but I'm assuming it's probably spilling all over under the tub, all over the floor, before falling into the drain hole and making it's way into the main drain. I haven't gotten a quote for this yet, but it would involve ripping out the tub, ripping up the tile floor, redoing the plumbing, and reinstalling the tub if it can be saved. I also found out the shower wasn't tiled correctly. We had to open up the walls behind the shower for an unrelated issue and found there's basically no support on the back of the tiles, so these will likely end up falling down at some point. The plumbing back behind the tiles was installed like a toddler did it as well. Oh, and in the attic, we found out the rain down shower heads were held up with drywall screws into a shim, so hardly holding onto anything.

3) The basement bathroom wasn't plumbed in properly, so a huge mold issue developed. We had to have the bathroom gutted and found 3 different plumbing leaks in the walls. The entire house needed to be fumigated to kill all the spores which ended up being like 300x higher than safe levels, along with an incredibly high level of black mold, all because we had to rip out the walls to access the plumbing. This was incredibly expensive.

There are a plethora of other problems but I'll stop there. To keep this as short as possible, it appears we need to practically gut the entire house to redo everything since nothing was done properly. What in the world do I even do in this situation? I talked to a real estate lawyer but he acted like it would be hard to actually win a case, even considering all the evidence. I can't afford to fix all these hazards and code violations.

Any advice or direction on what to even do in this situation would be great.
