The contractor takes on the liability, just like any other job. As part of our quality standards, all work needs to be up to code. We ingest the local code standards and include those in our quality controls. The controls are pretty rigorous, down to the specific materials used in jobs, including tracking the purchase, pickup, and usage of those materials.
