All ducts, air handlers, filter boxes, and building cavities used as ducts shall be sealed. Joints and seams shall comply with Section M1601 3 of the International Residential Code or 603.9 of the International Mechanical Code Duct tightness testing shall be conducted to verify that the ducts are sealed. A signed affidavit documenting the test results shall be provided to the jurisdiction having authority by the testing agent. When required by the building official, the test shall be conducted in the presence of department staff. Exceptions: 1. Duct tightness test is not required if the air handler and all ducts are located within conditioned space. 2.
