Where can I find laws for private home rentals?

I've contacted the city, county and LA Housing Department and 2 other agencies - they say that their laws only cover minimum 2 unit rentals and apartment buildings but not private 1 unit residential rentals. I've wanted to evict my terrible tennants more than once and even the lawyer I went to was going by the housing authority, forcing me to give them a 3 day pay or quit after they hadn't paid for 60 days and i was stuck with them paying and staying on. Where can I find the law for actual landlord renting their home to a 3rd party?? Please help!Where can I find laws for private home rentals?
