Splitting a renters policy sounds like the same logic as splitting rent, one bill, divided evenly. In practice, a shared policy usually protects less than two separate ones would, and in California, a lease requirement can complicate the "just get one policy" plan in ways that are worth knowing before you sign up for one together.
Renters insurance is written around an individual's belongings and liability, not a household's. Most insurers won't add a roommate as a fully covered policyholder, only as an "interested party" at most, which isn't the same as having their own property and liability protected. If one roommate causes damage or a liability claim, it can affect the whole shared policy. Each roommate carrying their own policy avoids that entanglement entirely.
State law doesn't mandate renters insurance in California. Landlords, however, can and often do require it as a lease condition. That distinction matters more than it seems: a legal requirement would apply to the property, but a lease requirement applies to whoever signed the lease.
This is where a shared-policy plan tends to fall apart. If a landlord requires proof of renters insurance and only one roommate's name is on the lease, that requirement is technically satisfied by that person's policy alone. It does nothing for the other roommates' belongings or liability. Anyone not named on the lease who's relying on someone else's policy to cover them isn't actually covered, whether the group intended to share one policy or not.
The appeal of one shared policy usually comes down to cost. Renters insurance premiums tend to be modest enough that the "savings" from combining into one policy often aren't worth what you'd give up: individual claims history, individual coverage limits, and not having your policy affected by a roommate's claim or a roommate's decision to cancel.
This is the quiet advantage of separate policies. When a roommate moves out, their policy leaves with them, and nobody else's coverage needs to change. A shared policy means renegotiating who's on it, what's covered, and how the premium gets split every time the household changes, which tends to happen more than once during a lease.

Most insurers won't add a roommate as a fully covered policyholder. They may be listed as an interested party at most, which doesn't extend full property or liability coverage to them.
No, state law doesn't require it, but landlords can require it as a condition of the lease.
No. Renters insurance covers the named policyholder's belongings and liability, not everyone living in the unit.
If each roommate carries their own policy, nothing changes for the others. A shared policy typically needs to be updated or renegotiated whenever the household changes.
