Black mold in newly leased space, guidance or are we stuck?
EDIT: Luckily our landlord got back to us this morning, I may have jumped the gun posting before I got an answer. It's better to be over informed than not enough. And Reddit is the best place for it. The contractor didn't repair it, and painted over it which was not what they were supposed to do, and the landlord is taking care of it. So luckily no testing or fighting on it! Thank you to everyone who responded, and for the advice. Very helpful, and I absolutely appreciate it!

We recently signed into a lease on a new commercial building for us. One of the things on the walkthrough we noticed was black mold and drywall bowing out in the walls of the office. The unit next door is in much worse shape with the office ceiling caving in and we are 99% certain it is a leak in that unit that has seeped into ours. We had asked about that getting repaired and didn't get a straight answer on it. We looked over the lease and under the work letter it does not state that it is an issue they are going to repair and resolve. We already signed the lease and I'm pretty sure we are boned and need to repair it ourselves since it isn't in writing. I know for residential dwellings there are clauses in the state of Nevada that landlord needs to repair that. Under NRS 118c, there are no provisions for the landlord maintaining a habitable premises, only the obligations that doors, windows, fixtures, and the roof need to be maintained. No provisions for mold repair or relief. If we have to repair it ourselves, oh well. I was curious to see if anyone has had a similar issue in the state of Nevada, or has some guidance about navigating this since we are still in the initial 10 days to submit an acceptance of the premises letter.

If the water is coming through the roof it is the landlord's responsibility, if it is coming through the neighboring suite through the roof ditto and otherwise say a drippy air conditioning system it seems to me it should be the tenant next door or the landlord if that space is vacant.", "replies": [{"id": "gw89azj", "text": "That's a good question, I made mention to them that the damage probably came from the unit next door. Both of these units have been vacant for about 8 years so there's been a good bit of rehab already. Luckily and I'll edit my post the landlord give you back to me today and said they will take care of it, that the contractor was supposed to have that done already.
