Tenant started a daycare business

[Mark W.]

It's come to my attention that one of my tenants has started a daycare business. I've looked into this and found out she became certified by the state earlier this year. So she's "legit"...however, my concern is liability.

My plan is to notify her that I am aware of the business and require her to obtain general liability insurance and add me as a named insured. If she refuses, I plan to kick them out (they are on a month-to-month agreement.)

Any other landlords have experience with this? Does this sound like a reasonable plan? I hate to kick this couple out with their two children, they are long-term tenants, but this makes me nervous. Even more so that she didn't tell me.
