Question

Is it legal in CA for a landlord to change the locks and charge the tenant after move-out if the landlord has the keys?

Answer

Yes, if the landlord has any reason to be concerned that the tenant kept any copies of the keys. The landlord can't rent a property to a new tenant when the old tenant may have keys to the place.
