Absolutely Require. Renter's insurance benefits you too. And S*** happens to everyone, eventually. Require you/your company be listed as additional insured. Unfortunately saved me 2x in last year - both for water damage in 1 bathroom apartments, required move-out. These things take way more time and money to resolve than you think! 1st, good tenant, didn't want to ditch but only option for me was either evict (at Christmas) or figure out temporary lodging. Her renter's insurance covered remediation of her belongings, move into storage and renting an RV that was delivered to the property for her to stay in during repairs. 2nd otherwise good tenant decided to play plumber blew out shower valve. His insurance also covered his lodging, ended up filing for water damage with my insurance but they pursuing his liability through his insurer. In both cases they continued to pay rent, which maintained cash flow. Other than deductibles, and of course insurance rate increases, was best possible outcome. Check agreements in your state for appropriate language that makes clear it's a condition of the lease, and lease can be terminated for non-compliance.
