I usually break it down into 5 pillars of asset protection (though in reality there are many more...)1st pillar is avoiding unnecessary and risky activities (don't drink and drive, insurance generally won’t cover your poor decisions) and take good care of your investments - these simple steps will help you prevent lawsuits before they even occur.2nd pillar is a good insurance policy as that cover the majority of your exposure.

Unfortunately the lease does not  clearly state what should occur in a situation like this.  

I dont see any harm in meeting with tenants you are inheriting.

Were you implying my comment was harmful?  

This is interesting while investing in a state with a high income tax.While California will allow you to utilize the losses from rentals as you occur them.

So what happens if there is an incident (fire, for example) that originates in and/or harms someone in an illegal unit?

It's currently not one of those 'boom' times; and I don't intend on counting on that to occur in the future either...so I'm treating it like a nice bonus if it does.

I continue to do the things I enjoy, but only as long as I am good at them, and I'm not causing myself harm in the process.  

To be frank, I know several property managers here who wouldn't manage properties there - too little rent income for them for the amount of trouble that can occur. 

If the average of the initial and follow-up short-term tests is less than 4 pCi/L, consider testing again sometime in the future.In certain instances, such as may occur when measurements are performed in different seasons or under different weather conditions, the initial and follow-up tests may vary by a considerable amount.
