Re: Tenant Calling Code Enforcement
If it was me, I would tell the complaining tenant that you have investigated the situation and do not have anything to prove their complaints. As such, there is really nothing you can do (which is entirely true) but should they have any proof of their claims, be sure to give you a call.
Short of terminating the other tenant's lease/rental agreement, if you can without cause because so far you do not have enough to terminate a lease for cause, there is really nothing you can do about this.
the one thing I find odd is:
they are complaining of body odor? Either there is a really stinky person in there, there is some other source of an odor that may need to be investigated, or they need their smellers checked. Odors are not easily disguised or removed. Have you noticed any odors?
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
