Her only option was to evict them which I think would be the better option then having them arrested.

What are the obligations of a California SFH family of owners who rent the attic (which is one big finished bedroom with private bath) out to a single man who went missing the 2nd of the current month we now find out he was pulled out of his rental car and extradited from California to New York on a warrant out for his arrest for a DUI accident that happened 2 years ago.Details of the accident not that have a keen interest but for what its worth will share his story: victim, a retired man, who sustained a brain injury 2 yrs ago from that incident, has apparently taken the turn for the worst and decided to press new charges for new medical costs and decline in mobility/quality of life, stress, anxiety etc for the accident 2 yrs ago which insurance paid out but victim wants the settlement amount (175k) a second time over? 

Assuming the claim won, does anyone ever able to collect money from tenant either through their pay check deductible, debt collector, get arrest warrant for non-payment ..... etcI guess tearing up the carpet, put a new floor/carpet on, cleaning fee, wall damage, I am also planning to charge her for breaking the lease (charge 2 months, is it reasonable?)

years later tax bills are coming and  the latest is a ticket asking for her arrest due to that property is  riddle with junk..    

How much of that 50K would need to be spent simply to arrest the downward trajectory of the business as it presently stands?

Third, I would let the guy know that stealing utilities is a crime (everywhere I know of in the US) and any further attempt at doing so you will simply contact the utility company, who can get a citation or arrest issued to the guy. 

I just talked a to a cardiac surgeon who teamed up with a real estate agent and a financial services expert to raise money for multifamily investments in Berkeley.

They were later arrested.
