Yes. As a precaution, you, your contractor, or kitchen designer should consult your city’s codes. A range hood is a type of ventilation system, which can be a safety issue. Though most building codes don’t require installing a range hood, there are rare occasions when you do have to consider it as part of your renovation. In addition, if you choose to install a range hood, there may be requirements that need to be followed, such as height requirements above the cooktop or how high a hood’s CFM must be for a given setup.
