IMO it makes no sense to remove seats. One mistake and your @$$ is getting sued big time!
Another thing I refuse to do is remove/re-install baby seats. Big no-no for me and my guys. If they want under them seats cleaned they can unbuckle them and re-install themselves.
I dont know why you'd want to do that. Say someone sues you, they're also naming your home owners insurance company in the lawsuit and maybe a lawyer can argue some kind of lien on your property. Who knows what kind of down the road affects that will have on your premiums, policies, etc. And then of course you're running the risk of tying up your home into a lawsuit.
General Liab for my business is about $600/year and I'm required to name my landlord as additional insured covered to $1M. Of course, your local rates will vary, but it shouldn't be outrageous to insure your business separately from your home.
