If your landlord requires that only one person maintains a renters policy for the apartment, you both won’t need renters insurance. That said, whoever is the policyholder will only have coverage for their own personal property. A renters policy won’t cover both of your belongings from damage unless you both have insurance or are on the policy.
While it may not be a requirement, it’s typically recommended that each roommate maintain their own policy. Renters policies typically only cost $6 to $30 a month for at least $20,000 of protection for your personal property, often making it well worth the cost.
