This will depend on your employment contract with the aforementioned company.
However the general rules are as follows:
Shared Accommodation: New Cabin Crew are expected to live in company provided, shared accommodation. The apartments are fully furnished and utility bills are paid by Emirates (however, you’ll have to pay for TV, phone and internet services).
Married Persons Accommodation Allowance: If you’re married you can choose not to live in shared accommodation. Instead, you’ll receive monthly accommodation allowance.
So they have an allowance if you want to stay with spouse. It will depend on your contract how much that is. That's pretty much it.
Good luck!
