I am having a new house built in Flat Rock, Michigan. Our blueprints specified 2 x 6 construction and our builder agreed to that type of construction. The blueprint is also filed in the city as 2 x 6 construction. After the first wall was put up we noticed that the builder was using 2 x 4 's instead of 2 x 6's. We immediately called him and informed him of the situation. He told us it was his house not ours. Now a complete shell is up using 2 x 4's. We went to the city inspectors and they told us it was a problem between us and the builder and that they could do nothing? We chose the lot because it is next door to our daughter. Do we have any recourse?
