I also agree. I think it depends on whether the hvac system is sized to handle a small extra room. Usually it is, and adding a duct will not be a problem. You could also add a return duct in the lanai. It is interesting that the building code may not allow adding a duct, unless you also raise the floor level and add electrical outlets. However, you can add a separate split system to the lanai. But, the contractors are using a loophole by calling the split system a "dehumidifier" instead of what it really is. The split system is actually an hvac unit, but, if they refer to it as an hvac system, they are violating the code, unless they raise the floor and add electrical outlets.
