What kitchen requirements apply to a legal basement suite in BC?

A legal secondary suite in British Columbia must have a fully functional kitchen with cooking facilities, a sink with hot and cold water, adequate counter space, storage, and the electrical circuits to safely power all appliances — and the kitchen must comply with BC Building Code, electrical code, and plumbing code requirements. The kitchen is one of the defining features that distinguishes a legal suite from a mere finished basement, and inspectors pay close attention to it.

The cooking facilities must include either a full-size range (stove with oven) or a cooktop with a separate oven. A microwave alone does not satisfy the cooking requirement. The range or cooktop needs a dedicated electrical circuit — a standard electric range requires a 40-amp or 50-amp 240-volt circuit with the appropriate receptacle. If you are installing a gas range, which is common in Metro Vancouver homes with natural gas service, you need a dedicated gas line installed by a licensed gas fitter and inspected by Technical Safety BC. A range hood or exhaust fan vented to the exterior is required to manage cooking fumes and moisture — recirculating range hoods are generally acceptable under BC Building Code, but exterior venting is strongly recommended in Vancouver's humid climate.

The electrical requirements for a suite kitchen are substantial and must be done by a licensed electrical contractor. At minimum, you need two 20-amp small appliance circuits serving the countertop receptacles, a dedicated circuit for the refrigerator, a dedicated circuit for the range, and a dedicated circuit for the dishwasher if one is installed. All countertop receptacles within 1.5 metres of the sink must be GFCI-protected. Receptacles must be spaced so that no point along the countertop is more than 900mm from an outlet. For a basement suite kitchen, all of this electrical work must be inspected and approved by Technical Safety BC before the walls are closed up.

The plumbing requires a kitchen sink with hot and cold water supply and a drain connected to the home's waste system. The drain must be properly vented to prevent sewer gas from entering the suite — an AAV (air admittance valve) may be acceptable in some situations, but a traditional vent through the roof is preferred. If the kitchen drain is below the level of the sewer connection, a sewage ejector pump may be needed, adding $2,000 to $4,000 to the project. A dishwasher connection requires its own drain and an air gap or high-loop to prevent backflow.

Counter space and storage must be sufficient for food preparation. While the BC Building Code does not specify exact counter dimensions for secondary suites, municipal inspectors expect a functional kitchen layout. Most successful suite kitchens in Metro Vancouver use either a galley layout (counters on two opposing walls) or an L-shaped configuration to maximize efficiency in the typically compact space. A minimum of 1.5 to 2.0 metres of counter length with at least 600mm of depth is a practical target, though more is better for tenant satisfaction and rental value.

The kitchen must also have adequate lighting — general ceiling lighting plus task lighting over work surfaces. Under-cabinet LED lighting is an inexpensive addition that dramatically improves the functionality of a small suite kitchen. The kitchen area needs smoke detection — a smoke detector must be located near but not inside the kitchen to avoid nuisance alarms from cooking.

In terms of costs, a complete suite kitchen installation in Metro Vancouver typically runs $8,000 to $20,000. On the lower end, that covers basic flat-panel cabinetry, laminate countertops, a standard range, refrigerator, basic plumbing, and the required electrical circuits. At the higher end, you get shaker-style cabinetry, quartz countertops, a dishwasher, higher-end appliances, and premium fixtures. Spending more on the kitchen is one of the best investments in a suite — it directly affects rental rates and tenant retention.
