- Yes, a range hood is required in all kitchens that contain a cooking appliance with a surface area of 300 square inches or more, including gas stoves.
When it comes to kitchen ventilation, understanding building codes is crucial. In British Columbia (BC), specific regulations govern the installation of range hoods. This article delves into the intricacies of these codes, answering the question: “Is range hood required by code in BC?”
Building Code Requirements
According to the BC Building Code, a range hood is required in all kitchens that contain a cooking appliance with a surface area of 300 square inches or more. This includes gas, electric, and induction cooktops, as well as ranges.
Exceptions to the Rule
There are a few exceptions to this requirement:
- Kitchens smaller than 10 square meters: In these small spaces, a range hood may not be necessary if there is adequate natural ventilation.
- Kitchens with other ventilation systems: If a kitchen has a mechanical ventilation system that provides a minimum of 10 air changes per hour, a range hood may not be required.
- Kitchens with open ceilings: In kitchens with ceilings that are open to other rooms, a range hood may not be necessary if there is sufficient cross-ventilation.
Types of Range Hoods
The BC Building Code does not specify the type of range hood that must be installed. However, there are various options available, including:
- Under-cabinet range hoods: These hoods are mounted beneath the kitchen cabinets, directly above the cooktop.
- Wall-mounted range hoods: These hoods are installed on the wall above the cooktop.
- Island range hoods: These hoods are suspended from the ceiling above a kitchen island.
Ventilation Requirements
The BC Building Code also specifies the minimum ventilation requirements for range hoods:
- Airflow rate: The range hood must provide an airflow rate of at least 100 cubic feet per minute (CFM).
- Ducting: The range hood must be ducted to the outside of the building through a minimum 6-inch duct.
- Makeup air: If the range hood exhausts more than 400 CFM, makeup air must be provided to prevent negative pressure in the kitchen.
Installation Considerations
When installing a range hood, it is important to follow the manufacturer’s instructions carefully. Some general guidelines include:
- Height above cooktop: The hood should be installed at a height of 24-30 inches above the cooktop.
- Ductwork: The ductwork should be as short and straight as possible to minimize airflow resistance.
- Electrical: The hood should be connected to a dedicated electrical circuit.
Penalties for Non-Compliance
Failure to comply with the BC Building Code requirements for range hoods can result in penalties, including fines and stop-work orders. It is essential to ensure that your kitchen meets all applicable codes and regulations.
