Legal Question in Landlord & Tenant Law in California

It would seem to me that it definitely is a reduction of services; I am not familiar with Hollywood's rent control laws but I would assume that is illegal and a significant reduction in services. Your problem is likely not that the management company has changed but rather the ownership has. I also assume that you have not signed a rental agreement for years but rather are on a month to month tenancy, so the prior written contract only applies to show what was done in the past but any changes in the oral agreements are permissible as long as their is mutual agreement. If the landlord offers something in addition to what was originally not covered in the written agreement, then when the next oral renewal of the rental agreement occurs that term is added to the contract. If a year after you had first rented you had to change from unit #1 to #3 and lived in the latter for 10 years, would they argue you have to move back into #1?

The parole evidence rule does not apply [you can not introduce evidence of oral changes to the written contract because to do so would mean that no written contract would be binding] because you are not dealing with one written contract that has existed for 9 years, you seek to show a change in the contract made before the last contract, and the behavior of the management company acting as the obstensible agent of the owner ratified by their actions the addition of terms to the later renewed contract.
