Does my in-law suite need a separate kitchen under Ottawa's zoning bylaws?

In general, yes. What turns extra living space into a separate dwelling unit is that it is self-contained, and a self-contained unit has its own kitchen. The CRA, for example, defines a secondary unit for the Multigenerational Home Renovation Tax Credit as a self-contained housing unit with a private entrance, kitchen, bathroom and sleeping area, and says a room without a kitchen does not qualify. Exactly how Ottawa's zoning by-laws define and treat secondary units is something to confirm with the City for your property. Ottawa currently has two zoning by-laws in effect (2008-250 and 2026-50) while appeals are resolved.

The good news is the kitchen does not need to be large. A compact kitchenette along one wall, with a sink, a cooking appliance, a refrigerator, and some counter and storage space, can give the occupant the ability to prepare meals independently. Your designer will confirm what the City expects to see on the drawings.

The kitchen adds real scope to the project. Plumbing needs hot and cold supply to the sink, a drain tied into your home's drain-waste-vent system, and ideally shut-offs so the suite's water can be isolated. If the suite is far from your existing plumbing, running new lines costs more, so ask for that to be itemized. Plumbing is a compulsory trade in Ontario, and you can check a plumber's authorization on the Skilled Trades Ontario Public Register.

Electrical work for appliances, receptacles and lighting needs an ESA notification or permit, done by an electrical contractor licensed by ESA. Your electrician will size the circuits for the appliances you choose and confirm protection requirements near the sink.

Plan ventilation from the start. Ask your designer what exhaust the kitchen needs and how the duct will reach the exterior, because routing it is much easier during framing than after the walls are closed. If you want a gas range or cooktop, the gas line must be installed by a TSSA-certified gas technician, and you should ask where carbon monoxide alarms are required.

The City always requires a building permit for a secondary unit in a house, and the drawings must show the fire separation between the two units. Permit fees are $12.75 per $1,000 of construction value.

If you skip the kitchen, you may end up with a guest suite rather than a separate unit, which affects what you can do with the space later. Before deciding, ask the City how your plan would be classified. You can compare itemized quotes from contractors in the Ottawa Construction Network directory.
