Basement Suite Wiring Toronto
Basement Suite Wiring Toronto
Toronto · Basement Suites
Basement suite, second unit and multiplex wiring across Toronto — capacity for two households, interconnected alarms and Toronto Hydro coordinated.
Toronto permits second suites in most houses, garden and laneway suites on many lots, and since 2023 up to four units on most residential properties. Every one of those units is another household on the electrical service — and the service is usually the first thing to check, because changing it involves Toronto Hydro and can set the schedule.
A panel inside the unit, accessible to the people who live there.
Smoke alarms that sound in every unit together.
Capacity for two or more households, with Toronto Hydro coordinated.
Options for metering units separately where it makes sense.
Three requirements shape most suite projects.
A second kitchen, a second laundry and separate heating or cooling add real load. A load calculation decides whether the existing service can carry both units.
If the service has to grow, the upgrade involves a Toronto Hydro disconnect and reconnection. Lead times of around a month are common, so it belongs at the start of the schedule.
Smoke alarms are interconnected across the units so a fire in one alerts the other, with carbon monoxide alarms where fuel-burning appliances are present.
What both units will draw, and whether the service carries it.
Panel location, alarms, metering and Toronto Hydro booked.
ESA inspections at rough-in and final.
