Annoying apartment owner

I made a custom apartment in sims 2, apartment life, and the bald owner of the apartment complex keeps coming into one of my renters' apartments and putting trash in their compost bin.

The door is locked but he keeps getting in. I've tried forcing an error and deleting him, but he just comes back in the morning, and I have to do it all over again. 

Can someone tell me how to fix this issue (without getting rid of the compost bin though, because they need their Zen garden).

Thanks in advance.
