I've carried E&O Insurance since 1986. Never had a claim. Think its a great relaxer to help me sleep better at night. I've never marketed it to realtors, clients, etc like "Use me cause I have a big E&O Insurance policy". IMHO, I think anybody doing that deserves to get sued a few times. I see many other inspectors do this as an advertising gimmick (and many of them get get sued regularly over petty BS). No other profession in my states (Missouri or Kansas) requires E&O or anything similar for a license. That statement includes engineers, architects, realtors, doctors, lawyers, termite inspectors, lead or asbestos inspectors, septic inspectors, appraisers, nurses, etc, etc. I think every inspector should be required to carry liability insurance (your ladder falls over and lands on the sellers car and damages it), before setting foot on someone elses property - but making E&O Insurance mandatory is dumb and prejudicial if other professions are not required to carry it to get a license.
