What is the minimum kitchen size for a secondary suite?

The Ontario Building Code doesn't specify a minimum kitchen size for secondary suites, but it must include specific appliances and meet functional requirements. In Ottawa, your secondary suite kitchen needs a sink, cooking facility, and refrigerator space, along with adequate counter and storage areas.

Kitchen Requirements for Secondary Suites

While there's no mandated square footage, your kitchen must be functional and safe. The Ontario Building Code requires adequate ventilation (typically a range hood vented to exterior), proper electrical outlets (GFCI protection near water sources), and sufficient lighting. Most successful secondary suite kitchens in Ottawa range from 40-80 square feet, depending on the layout and overall unit size.

Ottawa Unit Size Minimums

Remember that your entire secondary suite must meet minimum sizes: 28 square meters (301 sq ft) for a bachelor unit or 37 square meters (398 sq ft) for a one-bedroom. The kitchen is part of this total calculation. In practice, this means your kitchen will typically be 8-12% of your total unit size - so roughly 25-50 square feet in most Ottawa secondary suites.

Practical Design Considerations

Galley-style kitchens work well in secondary suites, maximizing efficiency in minimal space. You'll need at least 36 inches of walking space, and your counter should provide adequate prep area. Many Ottawa secondary suites use apartment-sized appliances (24-inch ranges, compact refrigerators) to maximize space while meeting code requirements.

Permits and Inspections

Your kitchen design will be reviewed as part of your building permit application with the City of Ottawa. The inspector will verify proper electrical, plumbing rough-ins, and ventilation before approving occupancy. Plan for electrical upgrades - most older Ottawa homes need panel upgrades to support a secondary suite's electrical load.

Next Steps

Before finalizing your kitchen layout, consult with the City of Ottawa Building Code Services (613-580-2424) to confirm your specific requirements based on your property's zoning and existing structure.
