Is a range hood exhaust fan required to vent outside?

Monday, May 18, 2020

A range hood fan is not required to vent to the exterior as long as the kitchen has other mechanical or natural ventilation (such as a window), and it is rated to be ductless. Here is how it is stated in both the International Residential Code (IRC) and the Residential Edition of the Florida Building Code at M1503.1: “Where installed in accordance with the manufacturer’s instructions, and where mechanical or natural ventilation is otherwise provided, listed and labeled ductless range hoods shall not be required to discharge to the outdoors."
