Do I need a permit to add a kitchen island?

In most cases, no — a basic kitchen island does not require a permit in Ottawa. However, whether you need one depends entirely on what's connected to the island.

A freestanding or furniture-style island with no plumbing, gas, or electrical connections is simply considered movable furniture under the Ontario Building Code. You can purchase it, place it, and use it without any permits or inspections. This covers the vast majority of kitchen islands homeowners add.

Where it gets more complicated is when you want to add services to the island. If you're planning to include a sink, a gas cooktop, or electrical outlets (including a dishwasher connection), then you're now dealing with trades work that requires permits and licensed professionals:

• Plumbing (sink or dishwasher): Requires a plumbing permit and must be done by or inspected through a licensed plumber. Running drain lines and supply lines to a centre island also involves cutting into your floor, which is a more involved job than most homeowners expect.
• Electrical (outlets, lighting, appliances): Any new circuits or outlet additions require an ESA (Electrical Safety Authority) permit in Ontario. This isn't optional — it's a legal requirement and protects your home insurance coverage.
• Gas (cooktop): Must be performed by a TSSA-licensed gas technician. No exceptions. This also requires a permit.

From a practical Ottawa standpoint, the cost of a simple freestanding island ranges from $500–$5,000+ depending on materials and size. A fully plumbed and wired custom island built into your kitchen renovation can run $8,000–$20,000+ when you factor in cabinetry, countertop, trades work, and permits. The permit fees themselves are relatively modest — typically $150–$400 depending on scope — but the trades work is where the real cost lives.

For DIYers, installing a freestanding island with no connections is a completely reasonable weekend project. The moment you're running water, gas, or new electrical to it, you're in licensed-trade territory. Unpermitted plumbing or electrical work can void your home insurance and create serious problems when you sell your home, as buyers' lawyers and home inspectors will flag it.
