I can't give legal advice, but every time I have something come up, it goes into my lease. A tenant destroyed a garbage disposal with a shot glass- the next thing in my lease was tenant payment for repairs not coming out of security deposit and specific terms for hourly labor charges.
Next, I had a tenant leave my unit filthy including grease all over the oven which took an hour of serious scrubbing. I made sure that there was a clause for move-out cleaning being paid at an hourly rate on top of costs for cleaning products.
At the moment, I have some noisy neighbors (I'm house hacking a 4-unit condo-style building). After that, I specifically wrote into my lease that if your neighbor can hear you and asks you to be quiet, you are required to comply! A series of complaints gets the tenant kicked out.
It may seem strict, but we are covering costs associated with what tenants leave behind. Bed bugs could get pretty costly. A while back I heard a news story about an apartment complex in a neighboring city getting condemned by the city for a bug problem! Granted, the owner was a total slumlord and refused to repair anything, but I'm confident that a large part of the issue with the bugs was caused by the tenants themselves.
I'm all for putting it in the lease!
