Frequently Asked Questions

Do Dundas secondary suites require a separate independent electrical panel?

While the ESA does not explicitly mandate a secondary physical breaker panel for all conversions, installing a dedicated 100-amp sub-panel for the basement is standard practice. This isolates the circuits, prevents total capacity overloads from shared cooking appliances, and provides tenants with direct access to their own breakers.

What are the structural requirements for building a separate basement entrance?

Adding a separate side or rear walkout entrance requires engineered drawings. The excavation must extend down below the frost line (typically 4 feet in Ontario) to prevent frost heaving, and it mandates reinforced poured concrete retaining walls, integrated footing drainage tied to a sump pump, and structural lintel support above the new concrete wall cutout.

Is an independent ventilation system mandatory for a basement apartment?

The OBC permits a shared forced-air heating and ventilation system only if it features automated duct smoke detectors connected to the furnace fan control to kill circulation during an emergency. To avoid trading air and cooking odors between units, installing an independent heat recovery ventilator (HRV) or ductless mini-split units is the superior technical path.
