In San Francisco & Oakland, breach of quiet enjoyment in bad faith if proven can triple damages.Good luck & maybe do an inspection every 6 months and call it Spring & Fall seasonal checkups and write those into the lease and get them to initial, sign off on it - and give the right written notice would be a compromise until you get more comfortable with your ability to vet and place good tenants.  

If you act in good faith according to the agreement you have with them, and as required by law, you'll fare much better should this go sideways and land in court.Standard disclaimers: I'm neither a lawyer nor licensed in CA, so feel free to disregard everything I've said!

In my state, leases are pretty easy for them to break, but, nonetheless, it shows good faith on your part.  

If they leave earlier, you are obligated to make a good-faith effort to find a new tenant.

If the tenant decides to cross the line and use the "mold" word for safety concerns, you send them a notice telling them they must vacate immediately and rent abates until repairs are completed to protect themselves as a gesture of good faith.   

The Stay of Execution If the eviction was not your fault or you cannot in good faith find a place to live, you may be able to convince a judge to grant you a Stay of Execution, allowing you to stay in your apartment for up to six months.

I had a real life faith experience in 1991.

Let me tell to you...THE SKY IS THE LIMIT if you TAKE ACTION, WALK BY FAITH and LET GOD DO THE REST (My personal testimony).

I'm 27 years old and recently decided to take the leap of faith and quit my job in order to focus 100 percent on Real Estate and making it a real career for myself.

In CA, if you keep any of the deposit in bad faith, you can end up having to reimburse the entire amount, plus up to three times the deposit in punitive damages, if I remember correctly - twice the deposit for sure, maybe three times.
