Technically you can make an excuse like check smoke alarm batteries, replace furnace filter, etc., but a determined tenant could push back on that too and say that they will tend to those things. 

Otherwise, they'll have an excuse for any mold that may occur in there.As far as the other stuff - If they break the vanity drawer, that's damage.  

Any excuse to get into the property and see how things are going.

Get a good lawyer immediately.California hates landlords and loves poor tenants with personal problems.Yes,she can sue you and probably will win a settlement from you after driving you insane first.Doubt she can prove that air conditioning had anything to do with his condition but,California judges like to look for any excuse to favor tenants.Good luck to you.

You can make excuses for them, but I think that is a bad idea.

I've gotten tired of the excuses.  

Either way, it seems like answer to your problem unless you aren't charging an application fee in which case taking that money out of pocket for an excuse to reject them seems silly.

She already knows you have a problem with her and you are looking for an excuse to get her out.
