We are building a new home in Northern Kentucky and the builder has determined (at the end of the build) that they need to build a retaining wall between the driveway and the backyard. The grade is too steep. The wall is 31" away from the driveway, but is over a 6-foot drop. I can't find any details about the code for retaining walls.
Is the builder required to have a barrier - natural or manmade?
