Does a window air conditioner need its own outlet in a Metrotown condo?

A window AC unit does not always need a dedicated circuit by code, but in a Metrotown condo the practical answer is almost always yes, and the electrical room situation makes it more complicated than in a house.

Here is why. Most window AC units draw 7 to 15 amps depending on their BTU rating. The BC Electrical Code requires that a single appliance drawing more than 50 percent of a circuit's rating be on a dedicated circuit, and a larger unit (12,000 BTU and up, typically 10 to 15 amps) will often cross that threshold on a standard 15-amp circuit. Even a smaller unit sharing a circuit with a bedroom's lighting and outlets can trip the breaker repeatedly under load, which is a sign the circuit is being pushed, not just an inconvenience.

The strata layer is what really shapes the answer here

In a Metrotown high-rise, your in-suite panel is typically 60 to 100 amps, fed from an electrical room on your floor. Before any new circuit is added, an electrician needs to do a load calculation to confirm there is capacity in your suite panel. If the panel is already loaded with baseboard heaters, a dishwasher, a microwave circuit and in-suite laundry, adding a 15-amp AC circuit may require a service upgrade at the electrical room level, which is common property under the Strata Property Act. That means strata council approval and likely an alteration agreement before work starts, regardless of what the electrical work itself costs.

The circuit itself, if the panel has room, typically runs $400 to $900 for a new dedicated 15 or 20-amp outlet in a condo, though finished walls, concrete construction and a long run from the panel to the window wall can push that toward the higher end or beyond. If a load calculation reveals the in-suite panel needs upgrading, add $1,200 to $2,500 for a sub-panel or service change, and factor in strata coordination time.

Because this is in Burnaby, the electrical permit and inspection go through the City of Burnaby's own electrical department, not Technical Safety BC. Your electrician pulls the permit from Burnaby, and Burnaby's electrical inspector signs off on the work. Make sure any contractor you hire knows this, confirms the permit is included in their quote, and has their Technical Safety BC contractor licence, which you should verify directly on the Technical Safety BC website before hiring.

For a smaller window unit under 8,000 BTU on a lightly loaded circuit, plugging into an existing outlet is often fine in practice, but if the breaker trips or the outlet feels warm, stop using it that way and call an electrician. A warm outlet or a breaker that trips under AC load is a real fault, not just a nuisance.
