Renter’s insurance - is it legal to require

[Peter Z.]

I incude in my lease agreements a provision disclosing I don’t carry renters insurance and advising tenant to obtain a policy. I’d like to start requiring renter’s insurance as part of the lease agreement. Can I legally do so (California)? If so, how do I get a tenant to maintain a policy year after year? If more than one occupant (e.g. BF/GF or roommates) do each one carry individual policies? Thank you for the input.
