Do I need builders risk insurance for a kitchen remodel
I see no reason for you to insure yourself during this project. I would advise you to be sure the individual subcontractors you hire carry contractors liability insurance. If for some reason a contractor makes a mistake that causes a major problem, you can litigate against that contractor and their insurance company. Example: carpenter drives a nail through a wire, gas  or water line that causes collateral damage, fire or water damage.  Ask for a copy of the contractors insurance binder sent directly from the insurance company to you.  Insurance companies do this at no charge and assures you the policy is in effect and current.
