New Owner of Duplex in Los Angeles - HAVE QUESTIONS!

[Daniel Howard]

Hi Investor, 

I am a new Landlord/Homeowner in Los Angeles and have purchased property that is rent controlled. Fortunate for me, I received the property vacant and have received EXCELLENT rent from my occupied unit. I am occupying the second unit, currently. 

As a previous renter, I would receive a one time fee that was passed on to me  from the owner. I am curious to know, what fee's can I pass on to my tenants by the city of Los Angeles? Or any other fee for that matter? 

May someone please help and advise? 

Thanks,
Dan
