A California Roommate Agreement for Apartment Co-Tenants is a legally binding agreement between two or more individuals who will be living in the same apartment. This agreement defines the rights and responsibilities of each roommate and outlines the obligations of the parties. It is important to note that this agreement should be signed by all the roommates and is legally enforceable. The agreement should include provisions related to rent and security deposits, responsibility for utilities and other services, rules for visitors, rules for common areas, rules for noise levels, and rules for sharing of personal items. The two main types of California Roommate Agreement for Apartment Co-Tenants are the Standard Roommate Agreement and the Roommate Contract. The Standard Roommate Agreement is typically used when the parties do not wish to make any changes to the terms of the agreement and simply wish to acknowledge their agreement. The Roommate Contract is more comprehensive and allows the parties to make changes to the agreement as needed. This agreement should also include provisions regarding termination of the agreement and must be signed by all the parties.
