TL;DR: What happens to a (rent-controlled) tenant if a landlord has to have mold in the walls remediated? How long does that process take? I have good reason to believe there is mold in the walls/ceiling at the unit I rent — the roof has leaked for over 5 years, a handyman trying to find the source of the leak once stopped working after cutting a hole in the wall because he found mold, and a lab found mold in an air sample I had tested. The sample didn’t find black mold fortunately, but I’m trying to get pregnant and the kind the lab did find may present concerns for a pregnant woman. I’m trying to figure out my next steps. The landlord knows about the first two things and has no intent to remediate or investigate further, so it’s on me to determine whether I want to push the issue. Since the issue is behind the walls, and based on where I know water has traveled through the ceiling, I can’t imagine this is an easy thing to remediate. How would this work in practice? My understanding is it would require opening up the walls down to the studs. Some questions I have: Would I have to leave while this work is being done? (From what I’ve read, it appears the answer is yes.) Would I have to move my belongings out? How long would this be expected to take? My lease provides that I’m entitled to pro-rated rent if I have to leave for any repair, so financially that issue is covered. This is an L.A. RSO-specific question, but I also worry that my landlord may be able to refuse to remediate until an order is issued by the city, and then will be able to use that order as the basis to evict me. I can’t find guidance on how such evictions work when the uninhabitable conditions can be remedied. I found a reference to the government being able to order that the unit be returned to the previous use, but I didn’t find anything yet on the tenant side for that — whether I’d have the right to move back in when the work is completed. Not directly relevant, but the building is also for sale. That’s the main reason I’m worried my landlord might see this as a legal way to evict me so it can be sold with a unit vacant (there is otherwise no way for the current landlord to evict me). Long story, but I’m not convinced the landlord is in any rush to sell, but I know the realtors are and might have influence. Ultimately, if I find the risk from the mold to be unacceptable, I have to do what I have to do, but I want to have as much info as possible before I proceed. (It’s uncertain whether the leak has been fixed, but at least some of the sources of the leaks have been fixed. Need to wait for the next heavy rainfall to say for sure whether the problem has been completely fixed, but I can no longer wait to deal with the mold.) Thank you!
