Kitchen Requirements for In-Law Suite Additions in Vancouver

The BC Building Code requires a secondary suite to have cooking facilities, but it does not specify a full-size kitchen — a kitchenette with basic cooking, refrigeration, and sink facilities satisfies the legal requirement. That said, what counts as adequate "cooking facilities" has practical minimums, and the City of Vancouver's development permit process may influence what your final kitchen looks like.

Under Section 9.37 of the BC Building Code, a secondary suite must include a food preparation area with a sink, a means of cooking, and a means of food storage (refrigeration). The code does not prescribe a minimum number of burners, a minimum counter length, or whether you need a dishwasher, oven, or full-size refrigerator. A compact kitchenette with a two-burner cooktop, an under-counter fridge, a sink, and a few feet of counter space meets the letter of the code.

In practical terms, most in-law suite kitchenettes in Metro Vancouver include at minimum a 24-inch or 30-inch range or cooktop with two to four burners, an under-counter or apartment-size refrigerator, a standard sink with hot and cold water, 6 to 10 linear feet of cabinetry, and enough counter space for basic meal preparation. This configuration fits comfortably in a galley layout as narrow as 7 feet wide and 8 feet long — roughly 56 square feet of dedicated kitchen space.

Ventilation is where many homeowners trip up. Regardless of whether you install a full kitchen or a kitchenette, the BC Building Code and City of Vancouver require exhaust ventilation over the cooking surface. A range hood or over-the-range microwave vented to the exterior is the standard solution. Recirculating (ductless) range hoods do not satisfy the code requirement for principal exhaust in a secondary suite. The exhaust must terminate outside, which means planning the ductwork route during the design phase — not as an afterthought.

From a cost perspective, a kitchenette in an in-law suite addition typically runs $8,000 to $18,000 depending on finishes and appliance quality. A basic setup with stock cabinetry, laminate countertops, a compact range, and an under-counter fridge can come in under $10,000. Upgrading to stone countertops, soft-close cabinetry, a full-size refrigerator, and a dishwasher pushes the cost toward $15,000 to $25,000. The plumbing rough-in cost is essentially the same whether you install a kitchenette or a full kitchen — you need hot and cold supply lines, drain, and a vent stack regardless.

One practical consideration that many families overlook: your in-law suite's kitchen design should match how the space will actually be used. If elderly parents will be living independently and cooking daily meals, a kitchenette with a two-burner cooktop and a bar fridge may feel frustratingly cramped within months. If the suite is more of a guest accommodation where the occupant shares meals with the main household most of the time, a compact kitchenette is perfectly adequate and saves valuable floor space in a smaller addition.

The City of Vancouver's guidelines also address suite livability in ways that go beyond the building code. While not prescribing a minimum kitchen size, Vancouver's planning staff review secondary suite applications for overall habitability, and a cooking area that's clearly inadequate for independent living may draw questions during the permit review. This is particularly relevant for suites that will be rented to tenants, where the Residential Tenancy Act creates additional expectations around habitable space.

For gas cooking, be aware that running a new gas line to the suite addition requires a gas fitter and a separate permit from Technical Safety BC. Many builders in Metro Vancouver now default to electric or induction cooktops in secondary suites to avoid this additional permit layer and cost. Induction cooktops are also safer for elderly occupants — no open flame, automatic shutoff, and the cooking surface stays relatively cool.
