Can the new management change anything from old contract?

Unfortunately, you have not provided enough information to really give an answer to your question. If you are on a month to month tenancy, then the terms may be modified with 30 days? notice. However, if you are on a lease for a specified term, then generally, the terms of the lease can?t be modified until the end of the lease term. A review of your specific paperwork would need to be done to really know where you stand.

If the old contract has no provision for its termination or changes being made, then the new owner is bound by the all contracts and their terms already in existence. Most contracts in California have a provision for ending the employment under certain grounds or time frame.
