California Code, Business and Professions Code - BPC § 22592

(a) If you are a tenant who is listing a room, home, mobilehome, condominium, or apartment, please refer to your rental contract or lease, or contact your landlord, prior to listing the property to determine whether your lease or contract contains restrictions that would limit your ability to list your room, home, mobilehome, condominium, or apartment. Listing your room, home, mobilehome, condominium, or apartment may be a violation of your lease or contract, and could result in legal action against you by your landlord, including possible eviction.

(b) You should review any restrictions on coverage under your homeowners' or renters' insurance policy related to short-term rental activities to ensure that there is appropriate insurance coverage in the event that a person sustains an injury or loss for which you are responsible, a person damages or causes loss to your personal or real property, or a claim or lawsuit is made against you or otherwise arises out of activities related to this hosting platform.
