Here’s a post one another forum. Since that forum doesn’t see many builders, they won’t get good answers. But y’all will have a useful perspective.
“We are in the design stage and getting ready to build. Before we contract with someone to build our house, I would like to see some discussion of what needs to be in the contract. What are the things that you builders want to make sure are covered? Those of you that have had your homes built, what do we need to look for and make sure that is covered?”
