Most of the laws we have are for the protection of the tenant.
For example rent control is different than not rent control... What type of lease do you have? Was the building built after 1987? (no rent control if built after 1987) etc. etc.
Call the city and they should give you direction.
Just to let you know, many (if not most) laws are there to protect YOU the tenant.

What city is the property in?
Is it a single family home or an apartment building...two or more on a lot?
Was the rental unit built before 1978?
Yes, they can raise the rent when your lease is up...but to what extent...the above questions need to be answered.
No, they can not ask you to leave because you called the city.
Call the Housing Authority for the City of Los Angeles 1-866-557-RENT if your property was built before 1978 and there are 2 or more units on the property...and you reside in the City of Los Angeles. There is a Rent Stabilization Ordinance that you may be covered under.
All the best,
