I am curious about the separate function AND ownership requirement for an addition to a non-certified building. We have several projects where we are adding to an existing building, and often the new addition is a wing or similar with the same function as the existing. Does this mean we essentially cannot submit it for certification? I have not had any experience where we're adding a new addition to a building and the addition has a different owner. We are doing as much as we can to differentiate the certified wing from the non-certified, but the "ownership" distinction is difficult for me to fathom. Any thoughts? Or is CIR always warranted?
