The BC Step Code, explained for homeowners.

The five steps of the BC Energy Step Code in plain language — what each level means for construction, comfort and operating costs, and which step your municipality requires.

Every new home in BC is built to a numbered energy 'step' — and that number quietly decides your comfort, your utility bills and your resale story for the next fifty years. Here's the whole system in plain language.

Each step is a measured whole-building efficiency improvement over the base building code, verified by an independent energy advisor with a blower-door test — not a checklist.

The Step Code doesn't tell builders how to build — it tests the finished house. Airtightness, insulation, windows and mechanical systems can be traded against each other, as long as the blower-door and energy model hit the step's targets. Most Metro Vancouver municipalities now require Step 3 or higher for new homes, and Vancouver pairs it with low-carbon heating requirements — which in practice means heat pumps.

What each step feels like to live in

1–2Code-minimum envelopeDrafts near windows, uneven rooms, higher bills
3Better insulation & airtightnessQuieter, steadier temperatures, lower bills
4High-performance windows, thick envelopeRooms hold temperature for hours; HVAC barely runs
5Net-zero-ready envelopeAdd solar and the home can produce what it uses

Our default: we build Step Code-ready envelopes as standard, not as an upsell — because the cost of doing it during construction is a fraction of retrofitting it later, and the comfort difference is the first thing owners mention at handover.
