Renter's Insurnace when there are multiple tenants

[David Tang]

What are people's thoughts around tenant's Renter's Insurance in Chicago? We recently signed a lease with tenants (2 people - Person A & B) where they have 1 renter's insurance. Person A has the renter's insurance while Person B does not, but Person B's belongings is "mostly covered" by Person A's Renter's Insurance. I think it is fine as long as their belonging are covered under someone's renter's insurance, but would most people request each individual tenant's have their own Renter's Insurance?
